Dev Mittar, Ph.D., Scientific Director of the ASM Health Scientific Unit discusses the use of metagenomic next generation sequencing to develop agnostic diagnostic technology, giving scientists and clinicians alike, a tool to diagnose any infectious disease with one single test. He also discusses how the ASM Health Unit is empowering scientists and leveraging microbial science innovations to address critical global health challenges and improve lives worldwide. Ashley's Biggest Takeaways The Division of Research, Innovation and Ventures is a small entrepreneurial arm of BARDA that takes on early-stage projects with high potential of turning into medical countermeasures. Prior to his role as Scientific Director for ASM Health, Mittar worked as a health scientist and program officer at DRIVe, where he focused on advancing high-impact science. He is particularly passionate about his work to develop agnostic diagnostics—a single test that uses metagenomic next generation sequencing to identify any pathogen from 1 clinical sample. Mittar discusses applications for this technology in surveillance (pandemic preparedness), variant detection, AMR and clinical settings (diagnosing complicated infections where etiology is not clearly defined). He also shares how a recent bout with illness emphasized the value and potential of this technology to save money, time, pain and suffering of the patient. Agnostic diagnostics can also help prevent the overuse/misuse of antibiotics, which are key factors in the spread of antimicrobial resistance. Furthermore, when this technology is coupled with the use of metatranscriptomics, it can provide information about the patient's immune profile that can be helpful in developing personalized treatment strategies, as opposed to a one-size-fits-all approach. ASM is organizing around 3 scientific units, ASM Health, ASM Mechanism Discovery and ASM Applied and Environmental Microbiology. These units will empower researchers and scientists to use science make a difference in the world and provide a forum for them to come together to shape the future of the field.

How do you react when a piece of food you're eating falls to the floor? Some people would throw it away in disgust, while others would still eat it, perhaps after rinsing it under water or blowing on it. Of course, there's those that abide by the five second rule. That's the popular belief that suggests any food is still fit for consumption as long as it hasn't been on the floor for longer than five seconds. So does the time a piece of food spends on the ground affect how likely it is to be contaminated by germs and other bacteria? Back in 2016, researchers from Rutgers University in the United States looked into the matter from a scientific approach, and published their findings in the Applied and Environmental Microbiology journal. How did they test the five second rule? What impact did the surface and food type have? So does eating food that's been on the floor make you sick then? In under 3 minutes, we answer your questions!

Melvyn Bragg and guests discuss the most abundant lifeform on Earth: the viruses that 'eat' bacteria. Early in the 20th century, scientists noticed that something in their Petri dishes was making bacteria disappear and they called these bacteriophages, things that eat bacteria. From studying these phages, it soon became clear that they offered countless real or potential benefits for understanding our world, from the tracking of diseases to helping unlock the secrets of DNA to treatments for long term bacterial infections. With further research, they could be an answer to the growing problem of antibiotic resistance.With Martha Clokie Director for the Centre for Phage Research and Professor of Microbiology at the University of LeicesterJames Ebdon Professor of Environmental Microbiology at the University of BrightonAnd Claas Kirchhelle Historian and Chargé de Recherche at the French National Institute of Health and Medical Research's CERMES3 Unit in Paris.Producer: Simon TillotsonIn Our Time is a BBC Studios Audio ProductionReading list: James Ebdon, ‘Tackling sources of contamination in water: The age of phage' (Microbiologist, Society for Applied Microbiology, Vol 20.1, 2022) Thomas Häusler, Viruses vs. Superbugs: A Solution to the Antibiotics Crisis?

With the rapid growth of new evidence from astronomy, space science and biology that supports the theory of life as a cosmic rather than terrestrial phenomenon, this book discusses a set of crucial data and pictures showing that life is still arriving at our planet. Although it could spark controversy among the most hardened sceptics this book will have an important role in shaping future science in this area.We are led to believe that modern science is free of all forms of irrational prejudice that plagued science over the centuries. In this book we document an instance when this is far from true in relation to the most fundamental aspects of biology — the question of the origin of life and its cosmic provenance. From the early 1980's evidence in favour of the theory of cosmic life and a version of panspermia, developed by Fred Hoyle and CW has grown to the point that its continued marginalisation, or even outright rejection, is a cause for serious concern. We present here the story of panspermia in which we ourselves have been directly involved…Milton Wainwright, BSc, PhD, FRAS was born in 1950 in the mining village of Fitzwilliam in the West Riding of Yorkshire. He obtained his BSc and PhD from Nottingham University, and after a short period as a National Research Council of Canada Research Fellow became lecturer in Environmental Microbiology at the University of Sheffield. Here, he taught and researched for forty-two years in the Departments of Microbiology and Molecular Biology and Biotechnology. He is an Honorary Professor at the Universities of Cardiff and Buckingham, UK, the University of Ruhuna, Sri, Lanka, and the Slavic University of North Macedonia; he is also a Visiting Professor of King Saud University, Riyadh, and one of the few biologists to be made a Fellow of the Royal Astronomical Society. He has published widely on the history of science, particularly on the germ theory, the history of antibiotics (notably penicillin) and alternative accounts of the history of natural selection and evolution. Nalin Chandra Wickramasinghe, MBE, BSc (Ceylon), MA, PhD, ScD (Cantab), Hon DSc (Sri Lanka, Ruhuna), Hon DLitt (Tokyo, Soka), FRAS, FRSA was born in 1939 in Sri Lanka. He commenced work in Cambridge on his PhD degree under the supervision of the late Sir Fred Hoyle, and published his first scientific paper in 1961 He was awarded a PhD degree in Mathematics in 1963 and was elected a Fellow of Jesus College Cambridge in the same year. In the following year he was appointed a Staff Member of the Institute of Astronomy at the University of Cambridge where he remained until 1973. He was formerly a Fellow of Jesus College Cambridge and Staff Member of the Institute of Astronomy, University of Cambridge; Formerly Professor and Head of the Department of Applied Mathematics and Astronomy, Cardiff University, UK; Director of the Buckingham Centre for Astrobiology, University of Buckingham, UK; Honorary Professor, University of Buckingham; Honorary Professor University of Ruhuna, Sri Lanka; Honorary Professor, Sir John Kotelawala Defence University of Sri Lanka; Adjunct Professor, National Institute of Fundamental Studies, Sri Lanka. He has also held visiting Professorial appointment in the US, Canada and Japan and Sri Lanka over the past four decades. Professor Wickramasinghe has published over 350 papers in major scientific journals, some sixty in the journal Nature. Together with the late Sir Fred he pioneered the theory of cometary panspermia the evidence for which has become compelling over the past few years. Finally, he is also the author/co-author of over thirty-five books.Become a supporter of this podcast: https://www.spreaker.com/podcast/earth-ancients--2790919/support.

Fungal invasions taking over living hosts is the thing of science fiction, but the humble button mushroom is taken steps to start. Often a fungi will specialize in symbiosis, invading or decomposing. But Mycena are starting to adapt to do all three. Humans, plants and fungi are in a complicated relationship where we influence the development of each other. The complex fungal toxin patulin is dangerous for humans, but can be broken down by microbes in soil. What can we learn from soil to fight back against fungal toxins and keep our fruit safe.

Oh boy. This episode may seeeeem crappy but it is certainly not a waste of your time. We're not kidding, while the episode is of course wonderful, mostly thanks to our wonderful guests, it is also certainly about poopy wastewater and what we can all learn from it. About those terrific guests: we mostly speak with Dr. Amy E. Kirby, Ph.D., MPH of the frickin' CDC (yes, that CDC) about the National Wastewater Surveillance System or NWSS. Did you know sewer water is not just a feature of teenage mutant ninja turtle habitats? Epidemiologists have been using the contents of our collectively owned chocolate waterfall to track disease since polio, but it was only in response to COVID-19 that the CDC launched the NWSS “to coordinate and build the nation's capacity to track the presence of SARS-CoV-2.” So we learn a bit about what all that means, as we talk weird waste, medication levels in the water, whether or not “silent but deadly” is flim flam, and more in this absolutely gushing sluicegate of an ep.BUT WAIT. That's not all. We got two little extra guests! First up, your ol' Dadward did a prank call on Amy Narimatsu of Shorerivers.org, so she has a fun little cameo, and we conclude with previous virology guest, Dr. Shannon Bennett, of the California Academy of Sciences to discuss what's happening with COVID these days, and why it's important to stay safe for those who still need protection.It's an absolutely bursting septic tank of an episode so… Hang on to your butts.Follow the CDC on TwitterLearn more about the CDC's National Wastewater Surveillance SystemFollow Dr. Bennett on TwitterA donation was made this week to ShoreRiversSponsors of OlogiesTranscripts and bleeped episodesSmologies (short, classroom-safe) episodesBecome a patron of Ologies for as little as a buck a monthOlogiesMerch.com has hats, shirts, masks, totes!Follow @Ologies on Twitter and InstagramFollow @AlieWard on Twitter and InstagramSound editing by Jarrett Sleeper of MindJam MediaTranscripts by Emily White of The WordaryWebsite by Kelly R.

Did you know that there are more organisms in a single teaspoon of soil than there are people on earth? On the latest episode of The Environment Edge podcast, Dr Fiona Brennan Soil & Environmental Microbiology researcher with Teagasc based in Johnstown Castle tells us all about soil health. A quarter of all life can be found in soil, so what actually lives in the soil beneath our feet and have we forgotten how important soil functions are in agriculture in relation to production, water quality, gaseous emissions and biodiversity? How healthy are our soils, are we hindering or helping our soil health and what should we be doing to get the most from our soil in a sustainable manner?

Soil microbes play an essential role in releasing nutrients from the soil in a form that our fruit trees and other plants can access. So, if your soil doesn't have a healthy and diverse microbe population, your fruit trees will not thrive. The problem is that microbes are so tiny that we can't see them with the human eye. How do we know if we have a good microbe population? According to the Soil Conservation Council of Canada all you have to do is bury a pair of 100% cotton underwear in the topsoil of your garden. Leave your undies in the ground for a couple of months. Then, when you dig them up see what they look like. If your soil microbes have been busy digesting and recycling organic matter, then all that will be left is the elastic waist band. To learn more about this process, I've invited two experts from the University of Guelph to talk about the "Bury Your Briefs Campaign" and about the role soil microbes play in keeping our fruit trees and other plants healthy. They are Cameron Ogilvie, Knowledge Mobilization Coordinator and Kari Dunfield, Canada Research Chair in Environmental Microbiology of Agro-ecosystems.

Denise Akob discusses her studies of microbial communities of contaminated and pristine environments using life science and earth science techniques. She discusses how to figure out “who’s there,” how to optimize select natural microbial activities, and her career path into government research. Julie’s Biggest Takeaways: Biogeomicrobiology straddles the life science and earth science fields. This is a growing area of research in the academic setting as well as in the private sector, where one can contribute to hydrogeology or bioremediation efforts. What happens on the surface when extracting resources like natural gases? Wastewater from hydraulic shale fracking, or fracking, can contaminate microbes. Preliminary data suggests that microbes that thrive in that wastewater can be a fingerprint for surface contamination, and this is one of the areas of active research in Akob’s lab. Additionally, microbes can respond to contaminants to remove that risk and remediate the spills. One trip to the field can provide samples for years of analysis. From one sample, scientists can conduct: Microbiome studies through amplicon sequencing to understand population structures. Metagenomics studies to understand functional potential. Biochemical studies to understand active metabolic processes. Akob asks how to make natural microbial degraders happy. For example: acetylene, a triple-bonded carbon compound, can inhibit degradation of chlorinated solvents, a potent groundwater contaminant. By studying the microbes that use acetylene as a primary energy source (acetylenotrophs), this removes this inhibition caused by acetylene and the chlorinated solvent-degraders can increase their activity. Akob studies pristine environments to understand natural microbial communities. A cave she studied in Germany was ‘ultra pristine,’ discovered while building a highway. Understanding natural processes, such as the biomineralization promoted during stalagmite and stalactite formation helps scientists imagine how to use tehse processes in other applications.

Application of Microorganisms in Environment
Viral diseases in plants offer advantageous platforms for virology work, which is why returning guest Marilyn J. Roossinck pushed her research focus in their direction. Her knowledge of virus, plant, and fungus interactions adds depth to Richard's continued collection of expert views on virus functions and habits in preparation for his book. She discusses Roles viruses have played in evolution to shape us and how evolution and adaptation have shaped viruses; Fascinating examples, such as how insects work in the transmission of plant viruses; and Surprising functions, such as how the cucumber mosaic virus results from three separate viral particles that infect together to form the genome capable of infection. Because plants are inexpensive, abundant, and easy to fit in a blender, they provide an excellent subject for virologists. Therefore, plant pathologist Marilyn J. Roossinck enlightens any attempt to understand virus behaviors. She's a professor of Plant Pathology and Environmental Microbiology at the Center for Infectious Disease Dynamics at the Huck Institute of Life Sciences at Penn State University. After introducing her motivation for embracing this field, she helps Richard along his quest for a bigger picture of virus capabilities. Through examples of symptoms of viral diseases in plants and animals, she discusses topics like the percentage of our genome that was converted from retrovirus RNA; these genes insure mammalian survival, making placental development possible. As she discusses human organisms as holobionts, listeners can get a much better understanding of the intricate beings we and all living organisms really are. For example, some fungal diseases in plants work with viruses for evolutionary adaptations such as the ability to survive heat. She mentions a virus discovered at Yellowstone that, if a fungus is present along with the virus, lends heat tolerance to certain plants. Similarly, the cholera bacteria in humans is only pathogenic when accompanied by a phage. In the midst of these interesting examples, she discusses her thoughts on virus mechanisms for entry and infection, viruses' ability to communicate or signal across cells, and the existence of "helper" viruses with different roles.

How can the intricate relationship between soil microbiota and plants be managed for improved plant health? Linda Kinkel discusses new insights into the plant rhizosphere and the ways that some Streptomyces isolates can protect agricultural crops against bacterial, fungal, oomycete, and nematode infections. Julie’s Biggest Takeaways: The soil microbiome is extremely dynamic, with boom-and-bust cycles driven by nutrient fluxes, microbial interactions, plant-driven microbial interactions, and signaling interactions. Finding the source of these boom-and-bust cycles can help people to manage the microbiome communities and produce plant-beneficial communities for agricultural purposes. Rhizosphere soil is soil closely associated with the root and is distinct from rhizoplane soil that directly touches the root. The endophytic rhizosphere are those microbes that get inside the root. Many scientists view these communities as a continuum rather than sharply delineated. Plants provide necessary carbon for the largely heterotrophic soil microbiota, and these microorganisms help the plants in several ways too: Microbes mediate plant growth by production of plant growth hormones. Microbes provide nutrients through mechanisms like nitrogen fixation or phosphorus solubilization. Microbes protect the plant from stress or drought conditions. Through a University of Minnesota plant pathology program, potatos were passaged in a field for over 2 decades to study potato diseases. Over time, researchers found fewer diseases in test crops, which led the plot to be abandoned in the late 1970s. In the 1980s, Dr. Neil Anderson planted potatoes to see if they would develop disease, but neither Verticillium wilt nor potato scab developed among the plants. Soil from the field (and on the potatoes) contained Streptomyces isolates that showed antimicrobial activity against bacteria, fungi, nematodes, and oomycetes. This discovery led Neil, new University of Minnesota professor Linda, and their collaborators to study the antimicrobial activity of natural Streptomyces isolates from around the world. Inoculation quickly adds specific microbial lineages to soil microbiome communities. Alternatively, land can be managed by providing nutrients to encourage the growth of specific species, like Streptomyces, within a given plot, but this takes longer to develop. How are soil microbiomes inoculated? Microbes can be: Added to the seed coating before planting. Placed in the furrow when the seed is planted. Distributed into the irrigation system.

The most abundant organism on Earth lives in its seas: the marine bacterium SAR11. Steve Giovannoni describes how the origins of SAR11 provided its name, and the ways that studying SAR11 have taught scientists about ocean ecology. He also discusses how the different depths of the ocean vary in their microbial compositions and what his big questions are in marine microbiology. Different depths of the ocean have different habitats, but the microbes vary continuously, based in part on light availability: Surface light facilitates photosynthesis by algal cells. These primary producers fix carbon for the entire ecosystem! Because nutrients are readily available, the cell concentration in surface waters can reach nearly 1,000,000 cells/ml. The twilight zone offers dim light. Microbes in this area mainly use carbon sources generated by the surface-dwelling microbes. Below a few hundred meters, cell concentrations drop to 10,000-100,000 cells/ml. The deep ocean has no light and the microbes that live here have significantly different biochemistries and metabolisms. SAR11 is small in both physical size and genome size (0.37–0.89 µm and 1.3 million base pairs, respectively). It is nevertheless the most abundant organism on the planet, with more than 1028 cells estimated to exist worldwide. These cells convert between 6-37% of the carbon fixed in the oceans daily. SAR11 in different niches have ecotypes with different specialties but look physically similar and have very similar genome sequences. Naturally, the most abundant cells in the ocean have the most abundant parasites: bacteriophages called pelagiphages infect SAR11 all over the world. SAR11 and pelagiphages are under constant evolution, though there doesn’t seem to be a CRISPR system in the Pelagibacter genome; these bacteria largely use other mechanisms to evade phage infection. SAR11 is like a house with the lights on all the time, in that the cells constitutively express most metabolic genes. For example, SAR11 metabolizes dimethylsulfoniopropionate (DMSP) into dimethyl sulfide (DMS) and methanethiol (MeSH), which can be produced as soon as the cells are exposed to DMSP. While this may seem energetically expensive, the cells must capitalize on their encounters with this transient resource, often found only at low concentrations, and this capitalization requires the investment of protein production. The cost of metabolic gene regulation outweighs the benefits in this particular case. SAR11 and SAR202 are the poles on the spectrum of heterotrophic marine bacteria. SAR11 is very efficient at accessing and using the organic compounds that come from the phytoplankton (also called the labile organic matter). SAR202, found in the deeper part of the ocean, specializes in hard-to-access carbon compounds that other bacteria can’t access. Links for This Episode MTM Listener Survey, only takes 3 minutes.

Many hospital-acquired bacterial infections are also drug-resistant. Amy Mathers describes her work tracking these bacteria to their reservoir in hospital sinks, and what tools allowed her team to make these discoveries. Mathers also discusses her work on Klebsiella, a bacterial pathogen for the modern era. Subscribe (free) on Apple Podcasts, Google Podcasts, Android, RSS, or by email. Julie’s Biggest Takeaways Nosocomial infections are a type of opportunistic infection: one that wouldn’t normally cause disease in healthy individuals. Once the immune system is compromised due to other infection or treatment, the opportunist bacteria take advantage of the conditions to grow to higher numbers and cause disease. How are different pathogens transmitted in the hospital? Previously, transmission was considered to occur from one patient to a second patient, perhaps via a healthcare worker. When patients from very different parts of the hospital began to come down with the same resistant strain of bacteria, without interacting through the same space or staff, researchers began to look at a different reservoir: the hospital wastewater. How does the bacteria get from the sink to the patients? The bacteria, existing in a biofilm in the pipe right below the drain, can be transferred in droplets when the water is run. These droplets can fall as far as 36 inches from the drain plate and can contaminate the sink bowl or patient care items next to the sink. Some of the solutions to decrease bacterial dispersion from hospital sinks are very simple: for example, offsetting the drain from the tap, which keeps the water from directly running onto the drain, helps decrease the force with which the water hits the drain and therefore decreases bacterial dispersion. The Sink Lab at University of Virginia couldn’t replicate the bacterial growth patterns seen in the rest of the building; in particular, there were fewer protein nutrients that promoted bacterial growth. By setting up a camera observation of sink stations used in the hospital, the team realized that the waste thrown down the sink (extra soda, milk, soup, etc) was feeding the microbial biofilm. This helps the CRE in the biofilms in the sinks thrive. Links for This Episode MTM Listener Survey, only takes 3 minutes. Thanks!

What happens to an infectious agent once it leaves the human body? Well, it ends up in our cars, airplanes, food, water, and soil. If we know how that contagion behaves “in the wild”, then we'll be able to kill it, filter it, or otherwise prevent it from proliferating, and potentially improve the lives of millions of people in the process. This is the study of Environmental Microbiology and it's a topic that today's guest has spent more than 30 years trying to understand. Dr. Syed Sattar is Professor Emeritus of Microbiology at the Faculty of Medicine, University of Ottawa. He is also a co-founder and Chief Scientific Officer at CREM CO. He's a world-renowned expert who regularly advises national and international agencies like the World Health Organization (WHO), and private-sector companies. We're also joined by Bahram Zargar, CEO of CREM CO. This is a company built on top of Dr. Sattar's extensive body of work that aims to speed the assessment, development, and promotion of innovative and sustainable strategies for environmental control of harmful microbes for a safer tomorrow. It blends engineering with environmental microbiology to enable a whole new level of scientific rigor. You'll learn: What happens to infectious agents once they leave the body? What can we do with that knowledge? How air travel and the international food market have eliminated borders in the battle against infectious disease. How engineering can support Infection Prevention and Control (IPAC) by enabling scientific rigor and validation. How this science can be used to develop new barrier technologies. What is lacking in today's IPAC efforts and where does it need to go? How disinfectants can lead to their own form of resistance (i.e. bugs resistant to cleaning) and may even contribute to antibiotic resistance. What's the biggest challenge in matching IPAC innovations with potential buyers in the healthcare system? Why we need to enable our “foot soldiers” (i.e. the cleaning staff and environmental services teams at hospitals) with proper training and tools to win this war. Why it's important for innovators and manufacturers to be more scientifically responsible (i.e. don't chase the bug of the month). Why the government needs to increase funding for research and development in IPAC. Why it's so important to stand on the shoulders of the IPAC greats that came before us and build on their work. A few key points that I'd like to highlight: There's very little money set aside by governments for research and development in IPAC. If there's no money, then the best researchers aren't motivated to go after these issues and innovation is starved. We've seen that recently in the U.S with the constant attack on the Prevention and Public Health Fund. We rely on our cleaning staff and Environmental Services (EVS) teams to do a very important job in the hospital, but we don't treat that position with much respect. “If our soldiers are not well trained and ill-equipped for battle, then how do we expect to win the war against the spread of infection?” In a world of increasing antibiotic-resistance and anti-microbial resistance, we must focus on prevention in IPAC.

Graciela Lorca studies genetic systems to find positive and negative microbial interactions that lead to disease. She talks about her discovery of chemical inhibitors for the citrus greening disease bacterium, Liberibacter asiaticus,and how a specific strain of Lactobacillus johnsoniimodulates the immune system and may help prevent development of diabetes in people. Subscribe (free) on Apple Podcasts, Google Podcasts, Android, RSS, or by email. Also available on the ASM Podcast Network app. Julie’s Biggest Takeaways Citrus greening disease, or huanglongbing, is a disease of citrus trees causing a major epidemic among citrus farmers around the world. The disease causes trees to sicken and eventually die, and is best diagnosed by PCR amplification of the bacterial DNA from the bacterium that causes the disease, Liberibacter asiaticus. Because the disease spreads through the tree at different rates, it’s important that many samples be tested for accurate diagnosis. Quarantining the disease has proved difficult, as undiagnosed roots can transmit the disease if they are used to hybridize with canopy plants. The disease becomes even harder to contain under bad weather conditions: the high winds of recent hurricanes can scatter the insect vector, the Asian citrus psyllid, leading to infection of new orchards. Although L. asiaticuscan’t be cultured, Graciela performed a screen on L. asiaticustranscription factors that were produced by E. coli. These were tested for inhibition by a chemical library, and discovered that a common treatment for gout, benzbromarone, inhibited protein activity. This discovery was confirmed using in vivoinfected plants and by expressing the gene in related bacterial species, Graciela and her team predict the protein plays a role in responding to osmotic stress. The protein target of the chemical differs widely between citrus greening disease and gout, but the protein-chemical interaction is similar enough to allow protein inhibition. Is there a link between the microbiome and diabetes? 10 years ago, Lactobacillus johnsoniican rescue animals that are predisposed to diabetes. L. johnsoniiinactivates a host enzyme, IDO, which regulates proinflammatory responses. Activated immune cells can travel to the pancreas and attack beta cells, leading to diabetes. Regulating the proinflammatory response by administering L. johnsoniias probiotics offers the opportunity to control development of diabetes in predisposed people.

Water, water everywhere but not a drop to drink or nutrient for that matter. The Ocean can sometimes be a inhospitable place with barely any nutrients to survive off. Other times it can be home to large ocean spanning algae blooms. The oceans from the Pacific to the Atlantic can hold lots of secrets (even fresh water) beneath the surface. This week we look at 3 different papers which outline strange parts of the ocean, from large algae blooms to hidden aquifers.References: Greta Reintjes, Halina E.

What happens to an infectious agent once it leaves the human body? Well, it ends up in our cars, airplanes, food, water and soil. If we know how that contagion behaves "in the wild", then we'll be able to kill it, filter it, or otherwise prevent it from proliferating, and potentially improve the lives of millions of people in the process. This is the study of Environmental Microbiology and it's a topic that today's guest has spent more than 30 years trying to understand. Dr. Syed Sattar is Professor Emeritus of Microbiology at the Faculty of Medicine, University of Ottawa. He is also a co-founder and Chief Scientific Officer at CREM CO. He's a world-renowned expert who regularly advises national and international agencies like the World Health Organization (WHO), and private-sector companies. We're also joined by Bahram Zargar, CEO of CREM CO. This is a company built on top of Dr. Sattar's extensive body of work that aims to speed the assessment, development, and promotion of innovative and sustainable strategies for environmental control of harmful microbes for a safer tomorrow. It blends engineering with environmental microbiology to enable a whole new level of scientific rigor. You'll learn: What happens to infectious agents once they leave the body? What can we do with that knowledge? How air travel and the international food market have eliminated borders in the battle against infectious disease. How engineering can support Infection Prevention and Control (IPAC) by enabling scientific rigor and validation. How this science can be used to develop new barrier technologies. What is lacking in today's IPAC efforts and where does it need to go? How disinfectants can lead to their own form of resistance (i.e. bugs resistant to cleaning) and may even contribute to antibiotic resistance. What's the biggest challenge in matching IPAC innovations with potential buyers in the healthcare system? Why we need to enable our "foot soldiers" (i.e. the cleaning staff and environmental services teams at hospitals) with proper training and tools to win this war. Why it's important for innovators and manufacturers to be more scientifically responsible (i.e. don't chase the bug of the month). Why government needs to increase funding for research and development in IPAC. Why it's so important to stand on the shoulders of the IPAC greats that came before us and build on their work. A few key points that I'd like to highlight: There's very little money set aside by governments for research and development in IPAC. If there's no money, then the best researchers aren't motivated to go after these issues and innovation is starved. We've seen that recently in the U.S with the constant attack on the Prevention and Public Health Fund. We rely on our cleaning staff and Environmental Services (EVS) teams to do a very important job in the hospital, but we don't treat that position with much respect. "If our soldiers are not well trained and ill-equipped for battle, then how do we expect to win the war against the spread of infection?" In a world of increasing antibiotic-resistance and anti-microbial resistance, we must focus on prevention in IPAC. Subscribe on iTunes Sign-up for our weekly newsletter!

Jennifer Moore-Kucera is an Associate Professor of Soil & Environmental Microbiology in the Department of Plant and Soil Sciences. She discusses soil microorganisms as key players in climate change. Her team samples soils and look at the soil stability and they evaluate the microbial community. She explains how soil stores 2 to 3 times more carbon combined by the atmosphere. 50 to 70 percent was lost but now they have a new technique to keep the carbon in the soil while increasing plant productivity and increase resilience. They are trying to seek funding to shift their management process to help mitigate climate change.

Directory of Open Access Journals Open Access to a lot of On-Line Journals. Using the search function is crude but easiest. National Center for Biotechnology Information Some Open Access. This provides info on US government-funded papers that are supposed to be public access but there are still kinks. It doesn’t have as many fermentation articles as one might like but it’s helpful. You can set up an automatic search and alert. Japan Science and Technology Information Aggregator A Lot of Open Access. A lot in Japanese but still a Lot of Good Stuff that You Can’t Find Elsewhere. Also, just because a journal is behind a pay-wall doesn’t mean, usually, that you can’t take a look at the abstract for it. If you find a couple of articles that you’re interested in, then your state library or state university library may be able to help you get a copy of the article.

Professor Milton Wainwright is Senior Lecturer in the Department of Molecular Biology and Biotechnology, University of Sheffield. This talk was given on 27th March 2014. This talk will explore Milton's work as a British microbiologist who became world famous for his claims to have found extra-terrestrial life in the stratosphere. His research interests are in Astrobiology and History of Science. He claimed that the idea of natural selection is not original to Darwin or Wallace theory. Also, he has claimed that the Red rain in Kerala is a biological entity. Wainwright has also written widely about the history of the discovery penicillin (including that Hitler’s life was saved by the drug) and streptomycin and on the theory that bacteria and other non-virus microbes cause cancer.

It holds the potential to provide a source of energy and jobs. Its extraction, however, is non-trivial and if done without proper safeguards can result in the degradation of water and air quality, and loss of land use. John Stolz, Professor of Environmental Microbiology at Duquesne University, will lead a discussion, providing an overview of the industry, the processes involved in extraction, and the environmental impacts of drilling into the Marcellus Shale. Hear the answers to questions like: What chemicals are used in the fracking process? What are the environmental concerns about extracting gas from the Marcellus Shale? Can earthquakes be caused by fracking? These questions and more are covered, including a Q&A session at the end. Recorded on April 26, 2011 at Carnegie Science Center in Pittsburgh, PA.
