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.

Dr. Maria Eugenia Inda-Webb, Pew Postdoctoral Fellow working in the Synthetic Biology Center at MIT builds biosensors to diagnose and treat inflammatory disorders in the gut, like inflammatory bowel disease and celiac disease. She discusses how “wearables,” like diagnostic diapers and nursing pads could help monitor microbiome development to treat the diseases of tomorrow. Subscribe (free) on Apple Podcasts, Spotify, Google Podcasts, Android, RSS or by email. Ashley's Biggest Takeaways Biosensors devices that engineer living organisms or biomolocules to detect and report the presence of certain biomarkers. The device consists of a bioreceptor (bacteria) and a reporter (fluorescent protein or light). Inda-Webb's lab recently published a paper in Nature about using biosensors (Sub-1.4 cm3 capsule) to detect inflammatory biomarkers in the gut. The work is focused on diagnosing and treating inflammatory bowel disease, but Inda-Webb acknowledged that that is a large research umbrella. The next step for this research is to monitor the use of the biosensor in humans to determine what chemical concentrations are biologically relevant and to show that it is safe for humans to ingest the device. It is believed that the gut microbiome in humans develops in the first 1000 days to 3 years of life. Early dysbiosis in the gut has been linked to disease in adulthood. However, we do not have a good way to monitor (and/or influence) microbiome development. Inda-Webb hopes to use biosensors in diapers (wearables) to monitor microbiome development and prevent common diseases in adulthood. In 2015, Inda-Webb became ASM's first Agar Art Contest winner for her piece, “Harvest System.” Inda-Webb is the 2023 winner of the ASM Award for Early Career Environmental Research, which recognizes an early career investigator with distinguished research achievements that have improved our understanding of microbes in the environment, including aquatic, terrestrial and atmospheric settings. Learn More About ASM's Awards Program Featured Quotes: We engineer bacteria to sense particular molecules of interest—what we call biomarkers—if they are associated with a disease. And then, we engineer a way that the bacteria will produce some kind of molecule that we can measure—what we call reporter—so that could be a fluorescent protein or light, like the one that we have in this device. The issue is that inflammation in the gut is really very difficult to track. There are no real current technologies to do that. That is like a black box. And so, most of what we measure is what comes out from the gut, and has its limitations. It doesn't really represent the chemical environment that you have inside, especially in areas where you're inflamed. So, we really needed technologies to be able to open a window in these areas. The final device that I am actually bringing here is a little pill that the patient would swallow and get into the gut. And then they engineer bacteria that the biosensors, will detect, let's say, nitrous oxide, which is a very transient molecule. And the bacteria are engineered to respond to that in some way—to communicate with the electronics that will wirelessly transmit to your cell phone. And from there, to the gastroenterologist. We make the bacteria produce light. If they sense nitrous oxide, they produce light, the electronics read that, and the [information] finally gets into your phone. Part of the challenge was that we needed to make the electronics very very tiny to be able to fit inside the capsule. And also, the amount of bacteria that we use also is only one microliter. And so, imagine one microliter of bacteria producing a tiny amount of light. Finally, the electronics need to be able to read it. So that has been also part of the challenge. In this case, you have 4 different channels. One is a reference, and then the other 3 are the molecule of your choice. So, for example, what we show in the paper here is that we can even follow a metabolic pathway. So, you can see one more molecule turn into the other one, then into the other one. I'm really excited about that. Because normally we kind of guess as things are happening, you know, but here you can see in real time how the different molecules are changing over time. I think that's pretty exciting for microbiologist. The immediate application would be for a follow up. Let's say the patient is going to have a flare, and so you could predict it more much earlier. Or there's a particular treatment, and you want to see what is happening [inside the gut]. But for me, as a microbiologist, one of the things I'm most excited about will be more in the longer term. One of my favorite experiments that I do with the students is the Winogradsky column, and everyone gets super excited. So, we all have nice feelings for that. And it's basically a column where we asked the students to bring mud from a lake, for example, and then some sources of nutrients. And then, after 6months, you will see all the layers, which is super pretty—beautiful, nice colors. But actually, that gives the concept of how the microenvironment helps to define where, or how, bacteria build communities. And so, what I think this device is going to do is to help us identify what is this microenvironment and to characterize that. And then, from there, to know if [an individual's] microbiome is leaning towards the disease state, or if it's already in a serious or dangerous situation, to think about treatments that can lead to a more healthy state. So, I would just say it's really to have a window into the gut, and to be able to give personalized treatment for the patient. So, one application: I was thinking, I'm from the Boston area. So, one problem we have is getting a tick bite, right? After that, you could actually have to go through a very traumatic, antibiotic regime. I would imagine, in that case, you could [use the biosensor to] get the baseline [measurement], and then if you need to take these antibiotics, the doctors can follow how your microbiome is responding to that. Because one of the problems is that antibiotics changed the oxidation level [in the gut], and that really affects a lot the microbiome. To that point, for example, I get to know patients that they were athletes, and then, after antibiotic treatment, they have serious problems with obesity. Their life gets really messed up in many ways. And so, what I'm thinking is, if we could monitor earlier, there are a lot of ways that we could prevent that. We could give antioxidants; we could change the antibiotic. There are things that I think the doctor could be able to do and still do the treatment that we know. And of course, [although] we talk a lot about how much trouble antibiotics are, for certain things, we still need [them]. [The multi-diagnostic diaper] is one of my pet projects. I really love it. So yeah, basically, the issue is that the microbiome develops in the first 3 years. People even say like, 1000 days, you know. But there's really no way to monitor that. And now we're seeing that actually, if the microbiome gets affected, there are a lot of diseases that you will see in adult life. So, if we will be able to monitor the microbiome development, I really believe that we'll be able to prevent many of the diseases of tomorrow. What happens is that babies wear diapers. So, I thought it was really a very good overlap. We call that “wearables,” you know, like devices that you can wear, and then from there, measure something connected with health. So, in the diaper, I was excited because—different from the challenge with the ingested device, which was so tiny—here, we don't have the limitation of space. So, we could measure maybe 1000 different biomarkers and see how that builds over time. We can measure so many things. One could be just toxic elements that could be in the environment. I try to do very grounded science, and so, my question is always, ‘what's the actionable thing to do?' So, I'm thinking if there was a lot of toxicity, for example, in the carpet, or in the environment where you live, those are the easiest things to change, right? Then also, other things connecting more with the metabolism. [Often] the parents don't know that the kid has metabolic issues. So, before that starts to build and bring disease, it would be best if you could detect it as early as possible. From there, with symbiotics, we are thinking there are a lot of therapies that could engineer bacteria to produce the enzymes that the kid can't produce. We could also [develop] other products, like for example, a t-shirt to measure the sweat. I'm also thinking more of the milk. I'm very excited about how the milk helps to build the microbiome in the right way. And that that's a huge, very exciting area for microbiologists. And so, we could also have nursing pads that also measure [whether] the mother has the right nutrients. My family, my grandparents were farmers, and in Argentina, really the time for harvest is very important. You can see how the city and really the whole country gets very active. And at that time [during a course Inda-Webb was taking at Cold Spring Harbor] in this course, I could see that with yeast we were having a lot of tools that would allow us to be much more productive in the field. And I thought, ‘Oh, this feels like a harvest system for yeast.' Yes. So that was how it [Inda-Webb's winning agar artwork, ‘Harvest System'] came out. I really love the people. Here, [at ASM Microbe 2023], I really found that how people are bringing so much energy and really wanted to engage and understand and just connect to this idea of human flourishing, right, giving value to something, and saying, ‘okay, we can actually push the limits of what we know.' How beautiful is that? And you know, we can learn from that. That was very exciting. ASM Agar Art Contest Have you ever seen art created in a petri dish using living, growing microorganisms?

This episode was recorded while at the American Society for Microbiology's (ASM) Microbe 2023 at Houston. I go over my favorite posters, sessions and more. It was great connecting with fellow microbiologists. Great posters such as Shewanella and oysters, frogs and potential compounds, and more. Of course, as a podcaster I had to sit through an episode of Editors in conversation.
This episode was recorded while at the American Society for Microbiology's (ASM) Microbe 2023. I went over what I liked about this conference as a first timer. I also talk more about other courses I took and my experience overall. Then I was joined by great company: Elizabeth Deyett and Jon Mitchell from the Microbe Moment, They have a podcast called the Microbe Moment with the Microbigals.

Dr. Jessica Lee, scientist for the Space Biosciences Research Branch at NASA's AIMS Research Center in Silicon Valley uses both wet-lab experimentation and computational modeling to understand what microbes really experience when they come to space with humans. She discusses space microbiology, food safety and microbial food production in space and the impacts of microgravity and extreme radiation when sending Saccharomyces cerevisiae to the moon. Ashley's Biggest Takeaways Lee applied for her job at NASA in 2020. Prior to her current position, she completed 2 postdocs and spent time researching how microbes respond to stress at a population level and understanding diversity in microbial populations. She has a background in microbial ecology, evolution and bioinformatics. Model organisms are favored for space research because they reduce risk, maximize the science return and organisms that are well understood are more easily funded. Unsurprisingly, most space research does not actually take place in space, because it is difficult to experiment in space. Which means space conditions must be replicated on Earth. This may be accomplished using creative experimental designs in the wet-lab, as well as using computational modeling. Links for the Episode: Out of This World: Microbes in Space.

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.

Some bacteria have the amazing ability to orient themselves using the earth’s magnetic field, due to the presence of an intracellular organelle called the magnetosome, which are estimated to have evolved 3 billion years ago. Dr. Arash Komeili is a Professor at the University of California Berkeley who studies bacterial magnetosomes. Dr. Komeili talks about how magnetotactic bacteria were discovered, how the earth’s magnetic field orients the bacteria in the aquatic environment, whether a Martian meteorite had bacterial magnetite in it, how bacterial magnetosomes can be exploited for targeting cancer cells, and whether bacterial magnetosomes could be used to generate energy. microTalk was pleased to be joined by Dr. Marvin Whiteley (Georgia Tech) when this podcast was recorded at the ASM Microbe 2019 conference in San Francisco, CA.

What happens when a bacterium gets old? Continuous culture of bacteria without any added nutrients can reveal the dynamics of “old” bacteria. Dr. Steve Finkel is a Professor at University of Southern California who studies what happens beyond “stationary phase” in bacterial cultures. Finkel studies the Growth Advantage in Stationary Phase (GASP) phenotype, which dominates in “old” bacterial cultures, and which represents adaptive evolutionary change. Finkel talks about how studying old bacteria gives insight into aging in other organisms, whether bacteria can divide forever, how bacteria choose not to divide unless they are certain they can finish dividing, how carbohydrate modifications in old bacteria can help illuminate diabetes, how small differences in bacterial growth conditions can result in huge differences in bacterial physiology, and how building Mission Control in his kindergarten class ignited his passion for science. microTalk was pleased to be joined by Dr. Marvin Whiteley (Georgia Tech) when this podcast was recorded at the ASM Microbe 2019 conference in San Francisco, CA. The microCase for listeners to solve is about Yakov Smirnov, a Siberian lab worker who comes down with a life-threatening disease at work.

Genomics-based technologies have revolutionized science. From microarrays to next-generation sequencing, genomics technologies are having a tremendous positive impact on all aspects of human health. Dr. Joe DeRisi is a professor at the University of California San Francisco and co-president of the Chan Zuckerberg Biohub. DeRisi has been at the forefront of developing and using genomics-based technologies to address infectious disease challenges. DeRisi talks about how genomics helped solve the mystery of dying leopard sharks in San Francisco bay, how a “virochip” array helped identify the SARS virus, how genomics can help identify unknown causes of encephalitis, how the sewer may hold the key to predicting infectious disease outbreaks, how computational capabilities represent the current bottleneck to global benefit from genomics technologies, and how the early mysteries surrounding the AIDS epidemic led him into science. microTalk was thrilled to be joined by Julie Wolf, “Meet the Microbiologist” podcast host from ASM, when this podcast was recorded at the ASM Microbe 2019 conference in San Francisco, CA. The microCase for listeners to solve is about Tess Tamoni, a retired teacher who gets a nasty infection while on vacation at a tropical resort.

Bacteriophages (“phages”), or bacterial viruses, are the most abundant biological entity on the planet, and the microbial world is shaped by these predators and parasites. The ability of bacteriophages to specifically target and kill their prey is being explored as an alternate therapy to antibiotics against various bacterial diseases. Dr. Graham Hatfull is a professor at the University of Pittsburgh who studies Mycobacterium tuberculosis, the causative agent of tuberculosis, and the phages that infect it. Hatfull directs the Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) program along with the Howard Hughes Medical Institute. Hatfull talks about how the SEA-PHAGES program has allowed entering students at more than 100 colleges and universities around the country to discover thousands of new phages, how phages isolated from the program were used to save the life of a patient infected with Mycobacterium, what the prospects are for phage therapy being used as treatment for other diseases, how bacterial resistance to phage infection impacts phage therapy, and how important research experience can be for students. microTalk was joined by Dr. Jimmy Ballard when this podcast was recorded at the ASM Microbe 2019 conference in San Francisco, CA. The microCase for listeners to solve is about Buck Shott, an aging Western movie stunt double who comes down with a potentially fatal infection after filming an action scene for “The Old, the Ancient, and the Geriatric”.
