In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Division of Clinical Microbiology at Mayo Clinic, is joined by Elitza Theel, Ph.D., director of the Infectious Diseases Serology Laboratory at Mayo Clinic, for a timely discussion on tick-borne diseases. Topics covered include:Observations from this year's tick season as we approach the end of July — a peak month for tick-borne disease transmission — along with trends in reported tick-borne pathogens over the past two decades.Algorithms developed by Mayo Clinic to guide clinicians in selecting the right tests for tick-borne and mosquito-borne diseases. The emergence of rare and esoteric infections and the challenges posed by vectors that carry and transmit multiple pathogens in a single bite.Shotgun metagenomics' growing role in the diagnosis of vector-borne infections.More resources Read "Update on North American tick-borne diseases and how to diagnose them" in the Journal of Clinical Microbiology for more insights from Drs. Pritt and Theel. You can also explore tools and information from Mayo Clinic Laboratories, including region-specific details, algorithms, prevention tools, and more.
Fluoroquinolones (FQs) are valuable given their broad-spectrum activity against Gram-positive and Gram-negative bacteria and their high penetration into various tissues. Yet FQs have also caused concern, with some market withdrawals, important and sometimes long-lasting adverse drug events, and substantial collateral effects on the microbiota. In this episode of Communicable, hosts Emily McDonald and Thomas Tängdén invite Staffan Tevell (Karlstad, Sweden) and Bernadette Young (Oxford, UK) to weigh in on the pro-con debate of FQ use, especially for periprosthetic joint infections (PJIs), which can entail longer treatment durations. They review the standard of care for PJIs, including FQs in combination with rifampicin vs other antibiotic combinations, the impact of the OVIVA trial advocating for early oral switch strategies, the long list of rare but important side effects, and how best to preserve FQs for clinical indications that most need them. This episode is a follow-up from Tevell and Young's recently published systematic review of the role of FQs in PJIs [1]. It was edited by Kathryn Hostettler and peer reviewed by Ljiljana Lukić of University Hospital for Infectious Diseases in Zagreb, Croatia. The executive producer of Communicable is Angela Huttner.

The adaptability of fungi to warmer temperatures is an obvious consequence of climate change. Perhaps less obvious is the role climate change has played on fungal pathogens emerging as a global health concern. While humans are mostly protected from fungal infections by our immune system and body temperature, a warming global climate could subvert the status quo. Some fungi are already adapted to warmer temperatures and causing invasive acute infections in humans: Candidozyma auris, Cryptococcus neoformans, and Aspergillus fumigatus, to name a few. In this episode of Communicable, Angela Huttner and Josh Nosanchuk invite Arturo Casadevall, a Bloomberg Distinguished Professor at Johns Hopkins and this year's recipient of ESCMID's Excellence in Science Award, to discuss the world of fungi and their pathogenic potential in a warming world. Other topics include how to prepare for their emergence as a health threat, how fungi can be harnessed for applications that can benefit us, and ultimately answering the question Casadevall himself posed in the title of his recently published book, What if fungi win?This episode was edited by Kathryn Hostettler and peer reviewed by Robin Aerts of University Hospital Antwerp, Belgium.

Bacterial vaginosis (BV) was long considered not to be a sexually transmitted infection (STI), and treatment was only for women to bear. That was the convention at least until Catriona Bradshaw and her team at the Melbourne Sexual Health Centre published their groundbreaking clinical trial results earlier this year, demonstrating that treating male partners of women with BV prevented recurrence in those women. In this episode of Communicable, hosts Angela Huttner and Annie Joseph welcome back Bradshaw to discuss her trial's design, results, and clinical implications—with some guidelines already updated to include male partners in BV treatment regimens. The conversation also explores the complexities of BV diagnosis, the challenges of trial execution in general, and future research directions.This episode was edited by Kathryn Hostettler and peer reviewed by Arjana Zerja (Mother Theresa University Hospital Centre, Tirana, Albania)ReferencesVodstricil LA, et al.

Fungal diseases are becoming more common, more dangerous, and more difficult to treat. There's concern that they may cause the next global pandemic. Rising global temperatures, better survival rates for vulnerable patients, and increased medical interventions contribute to the rise in fungal infections. Access to effective diagnostics and treatment remains limited, with significant disparities between high and low-income countries. Treating fungal infections is becoming more challenging as they build resistance to the drugs used to treat them. New therapies are being developed, including treatments that disrupt fungal DNA replication or interfere with essential proteins, offering some hope for long-term control.Contributors: Adilia Warris, Professor in Paediatric Infectious Diseases, University of Exeter, UKRita Oladele, Professor of Clinical Microbiology, University of Lagos and Lagos University Teaching Hospital, NigeriaArturo Casadevall, Professor and Chair of Molecular Microbiology and Immunology, Johns Hopkins Bloomberg School of Public Health, USMichael Bromley, Professor in Fungal Disease, University of Manchester, UKPresenter: Tanya Beckett Producer: Louise Clarke Researcher: Maeve Schaffer Editor: Tara McDermott Technical Producer: Richard Hannaford Production co-ordinator: Tammy Snow(Image: Aspergillus fumigatus, seen under an optical microscope.

There are many challenges in the microbiology laboratory. As a leader, you have to deal with things like validations, verifications, and knowledge of regulations among other things. As a microbiologist in a non-leadership position you need to be familiar with some of these as well. With so much information out there, where do we go? In this episode Luis is joined by Dr. Rebekah Martin, author of the “101 Topics for Clinical Microbiology Laboratory Leaders” book. This book was made in order to bring all of this information to one place. In the episode Dr. Martin discussed the process of writing the book, what type of content it has, and more.

Picture this, you wake up one morning with nausea, body aches, abdominal pain, and despite sleeping all night, you are exhausted. You then find yourself running to the restroom with watery and somewhat explosive diarrhea. You think to yourself – what could this be? Well, if the year was 2023, in the summer and you happen to live in Texas, chances were somewhat high that you had probably had cyclosporiasis. And today, we are going to talk about this particular parasite and focus in on what our options are for detecting it given that it is not routinely picked up on O&P exams. And while there are molecular panels out there that include Cyclospora as a target, as our speakers will share, there is an easier and cheaper approach we can consider to quickly ID this pathogen.

Rising anti-vaccine sentiment and dissemination of misinformation are threats to public health. In the US, calls to revoke certain public health mandates have been proposed by likely members of the incoming administration, among them vaccination against polio. The fourth instalment of the Nightmare Series is both a cautionary tale and an effort to preserve and share clinical expertise on how to diagnose and manage polio and rubella in a world where, until now, few doctors have had to face these illnesses in the clinical setting. Host Angela Huttner welcomes Professor Emeritus of Infectious Diseases Bernard Hirschel at the University of Geneva and Dr. Kerrigan McCarthy of the Centre for Vaccines and Immunology at South Africa's National Institute for Communicable Diseases (NICD) for that discussion.
