Ep 66Updates on Testing for Vaginitis/Vaginosis (JCM ed.)
As many of you are likely aware, May is recognized as Women's Health Care Month by the National Cervical Cancer Coalition, and this year, the CDC has identified the week of May 14th as National Women's Health Week. So, what better way to recognize these national events on the podcast than to talk about diagnostics for a number of extremely common and uniquely female issues – of course, I'm talking about infectious causes of vaginitis and vaginosis. Classically, diagnosis of these infections has been done at the point-of-care using wet mount microscopy and assessment for various clinical criteria, all approaches associated with some interpretive subjectivity, and let's say imperfect performance characteristics. As a result, molecular solutions for detection of the various pathogens associated with vaginitis and vaginosis are now increasingly available for use in clinical laboratories, and also at the point-of-care, and as is the post-COVID trend, a number of these assays, including the one we are going to discuss today, can be performed on both clinician and patient self-collected samples Guests: Dr. Rebecca Lillis - Associate Professor of Clinical Medicine at Louisiana State University Health Science Center and the Medical Director of the LSU-CrescentCare Sexual Health Center in New Orleans. Dr. Barbara Van Der Pol - Professor of Medicine and Public Health at the University of Alabama at Birmingham Links: Clinical Evaluation of a New Molecular Test for the Detection of Organisms Causing Vaginitis and Vaginosis This episode of Editors in Conversation is brought to you by the Journal of Clinical Microbiology and hosted by JCM Editor in Chief, Alex McAdam and Dr. Elli Theel.

Ep 64Susceptibility Testing for Piperacillin-Tazobactam (JCM ed.)
Susceptibility testing for piperacillin-tazobactam has undergone rapid evolution, largely driven by some surprising results from the MERINO trial, which compared the efficacy of piperacillin-tazobactam and meropenem for treatment of patients with ceftriaxone-resistant E. coli or Klebsiella pneumoniae bacteremia. We discuss how the results of the MERINO trial led to reconsideration of breakpoints for pipercillin-tazobactam at the Clinical Laboratory Standards Institute, or CLSI, how the breakpoints were changed, and how well commercial platforms perform piperacillin-tazobactam testing using FDA or CLSI breakpoints. Spoiler alert: the news isn't great. If you are interested in beta-lactam/beta lactamase combinations, you should check out the previous episode of this podcast, hosted by our friend Dr. Cesar Arias, the Editor-in-Chief of Antimicrobial Agents and Chemotherapy. Cesar and the guests did a great review of recent developments in this fast-moving area.

Ep 62Avoiding HIV False Positives (JCM ed.)
We can probably all agree that any false positive test result is bad, but I think it's safe to say that some false positives, like a false positive HIV test for example, is much more anxiety provoking than others. And when it comes to HIV, there have been a number of key advances in the field over the past decade, include the development of improved diagnostics and optimized algorithmic approaches, all of which have allowed for earlier detection of infected patients, and particularly those with acute HIV. Among these advancements has been the development of 4th and 5th generation serologic assays, which offer multiple benefits over prior assay versions, but unfortunately, are not immune to the possibility of false positive results. So, confirmatory test remain a necessary – the challenge though is that depending on the institution and environment, the turnaround time for such confirmatory testing can be prolonged, leaving patients and clinicians in a kind of diagnostic limbo. So, is there a way to minimize the risk of false positive first-tier HIV serologic results? And that is the question will be the focus of our discussion today.

Ep 60Molecular Testing for Periprosthetic Joint Infections (JCM ed.)
The applications of large multiplex panels for detection of pathogens have greatly expanded in the past several years. Initial tests were for detection of respiratory viruses, and the first such test was labor intensive and vulnerable to frequent contamination. Since then, additional sample types have been added, such as cerebrospinal fluid and positive blood culture broths, and tests are easier to perform and reasonably reliable. We discuss a research use only multiplex PCR assay for detection of pathogens in joint infections, and learning how it compares to targeted metagenomic sequencing and culture for detection of pathogens in periprosthetic joint infections. Guests: Dr. Marisa Azad - Assistant Professor of Medicine in the Division of Infectious Diseases at The Ottawa Hospital and an Associate Clinical Scientist at the Ottawa Hospital Research Institute. Dr. Robin Patel - Co-Director of the Bacteriology Laboratory at the Mayo Clinic, where she is Professor of Medicine and Professor of Microbiology.

Ep 58The Best Clinical Microbiology Papers of 2022 (JCM Ed.)
As we enter into the holiday season, many of us look forward to celebrating long-standing traditions with family and friends, which is no different from us here on the podcast! While not necessarily as long-standing as some of the other classic holiday traditions, after 2.5 years on air, we on this podcast have established our own end-of-year tradition, which is to take a look back at some of our favorite papers or more intriguing manuscripts published in the Journal of Clinical Microbiology over the past year. And so as you'll see, thanks to the different areas of expertise and general interest among our panel today, we've selected quite a variety of papers to discuss, ranging from evaluation of new blood culture systems to use of metagenomics for infective endocarditis and to the potential application of interferon gamma release assays for detection of Histoplasma infections. And so, suffice it to say, there will be something of interest for everyone listening. But, for those watching today, you are clearly getting an extra special treat as you get to see us do this episode wearing our best holiday gear and accessories. Guest: Dr. Trish Simner.

Ep 57How Can Clinical Microbiology Labs Contribute to Antimicrobial Stewardship? (JCM ed.)
Deciding how extensively to work up and report respiratory cultures is the worst. There are useful guidelines on how to approach this. But, in my experience, very few laboratories strictly follow these guidelines. That can be because of concerns about under-reporting pathogens or about over-reporting microbiota, or it can be the result of pressure from clinical staff to report more organisms than the guidelines suggest. Today, we'll be talking with two guests about their study on how over-reporting of organisms from respiratory tract cultures can lead to over treatment with antimicrobials. Guests: Dr. Sarah Parker, pediatric infectious disease specialist at Children's Hospital Colorado and the Medical Director of the Antimicrobial Stewardship Program. Dr. Andrea Prinzi, infectious disease medical science liason with bioMerieux.

Ep 55Machine Learning and Artificial Intelligence in the Clinical Microbiology Laboratory (JCM ed.)
The idea of applying machine learning and digital pathology platforms to everyday workflows in the clinical microbiology laboratory has become increasing intriguing and appealing, especially as labs continue to optimize efficiency in the midst of workforce shortages. The promise of this new digital frontier is multifold, including decreasing turnaround time and potentially cost, and freeing up technologist time to focus on higher yield activities in the lab. Many labs have now taken the initial leap into automated culture and imaging systems, but what's next? Are the digital pathology AI algorithms ready for prime-time in clinical microbiology labs? Is the future now?

Ep 54How Proposed Change to US Regulation Could Impact Clinical Microbiology Labs (JCM ed.)
There are a number of regulatory proposals under consideration which could have important effects on clinical microbiology labs, and clinical labs more generally. First, the VALID act would change how clinical tests are regulated with particularly important implications for laboratory-developed tests. Second, the Centers for Medicare and Medicaid Services has proposed changes to the educational requirements for lab directors under CLIA and additional changes that would increase the fees that clinical labs pay to CMS. If you have been waiting for someone to explain these changes and how they could affect your lab, you've come to the right podcast.

Ep 52The Inoculum Effect of Antibiotic Susceptibility Testing (JCM ed.)
The inoculum effect of antibiotic susceptibility testing is often discussed at playgrounds and infectious diseases conferences, but many of us don't really have a clear definition of what it is or a good understanding of its importance. We'll be talking about the inoculum effect and susceptibility testing of Staphylococcus aureus with cefazolin. Some of the questions we'll discuss are: • What exactly is the inoculum effect and how is it measured? • Does the inoculum effect have clinical significance? • How common is the inoculum effect with Staph aureus and cefazolin?
Ep 51Diagnosis and Treatment of Monkeypox (AAC ed.)
As July 26, the world has documented 19,188 cases of monkeypox, with 3,591 cases in the US alone, making the US the country with the most known infections amid the global outbreak. The WHO has declared monkeypox a public health emergency. Although this disease has been known for years, certain features suggest that we are facing a unique outbreak of monkeypox with the potential for worldwide spreading. In this special podcast edition of Editors in Conversation we will discuss the diagnosis and treatment of monkeypox with experts in the field who have dealt with significant number of cases in the US.

Ep 46Prevalence and Mortality Associated with Bloodstream Infections (JCM ed.)
It is estimated that anywhere from 575,000 to 677,000 bloodstream infections occur annually in North America, with approximately 40,000 of those directly linked to patient mortality in the United States, making bloodstream infections the 11th most common cause of death in the US according to the Centers for Disease Control and Prevention. The detection of bloodstream infections and subsequent identification of the etiologic agent or agents is an essential role played by all clinical microbiology laboratories, day-in and day-out for routine patient care. So, today, we are going to dive into a recently published study in JCM, looking at organism-specific bloodstream infection prevalence rates and their individual mortality risks relative to patients with either negative blood cultures and in those for whom blood cultures were not ordered. Guests: - Dr. Nick Daneman - senior author on the manuscript, is a Clinical Scientists in the Division of Infectious Diseases at Sunnybrook Health Sciences Centre at the University of Toronto, and a Adjunct Physician at Public Health Ontario. - Dr. Kevin Brown is a Scientist at Public Health Ontario and Assistant Professor at the University of Toronto This episode of Editors in Conversation is brought to you by the Journal of Clinical Microbiology and hosted by JCM Editor in Chief, Alex McAdam and Dr. Elli Theel.

Ep 45Consensus on B-lactamases (AAC ed.)
This episode is dedicated to the memory of the late George A. Jacoby, who was a pillar in the B-lactamase research community and a leader in the field of antimicrobial resistance. Assigning names to b-lactamase variants has been inconsistent and has led to confusion in the published literature. The common availability of whole genome sequencing has resulted in an exponential growth in the number of new b-lactamase genes. In November 2021 an international group of b-lactamase experts met virtually to develop a consensus for the way naturally-occurring b-lactamase genes should be named. Topics discussed: The inconsistencies in B-lactamase nomenclature Guidelines for publication of new alleles and newly discovered B-lactamases Future needs of consensus among the b-lactamase community Guests: Patricia Bradford PhD., Antimicrobial Development Specialists LLC Karen Bush PhD, Professor of Practice, Biotechnology and Interim Director, Biotechnology Program, Indiana University.

Ep 44Multiplex PCR for Predicting Antibiotic Susceptibility (JCM ed.)
Antibiotic susceptibility testing is too slow. Faster identification of microorganisms is now common, as many laboratories use MALDI-TOF or molecular technologies for quick and definitive identification of bacteria. Improvements in susceptibility testing have lagged, as we continue to use tests that take a day for results, and which have not significantly changed in decades. Rapid phenotypic testing has can only be done on limited sample types, using a dedicated platform, and it has not been widely adopted. Tests for rapid genotypic testing usually include only a few genes and require confirmation by phenotypic testing. What are the prospects for fast susceptibility testing? Guests: Dr. Trish Simner. Trish, Associate Professor of Pathology at Johns Hopkins Medicine, where she is also Director of the Medical Bacteriology and Infectious Disease Sequencing. Dr. Dan Rhoads. Dan is the Section Head of Microbiology at the Cleveland Clinic, where he holds The Belinda Yen-Lieberman, PhD, and James M. Lieberman, MD, Endowed Chair in Clinical Microbiology. Trish and Dan are first and last authors on a paper in press at JCM. The title is "Multicenter Evaluation of the Acuitas AMR Gene Panel for Detection of an Extended Panel of Antimicrobial Resistance Genes among Bacterial Isolates." Topics of Discussion • Scope of the AST problem • Conventional AST – how long does it take? • General approaches to reducing the time for AST – targeted genotypic (PCR), whole genome sequencing, and faster phenotypic methods. What do you see as potential for each? • What is the Acuitas AMR Gene Panel and how does it work? • Study design • Summary of results • Discrepant results • Workflow • Where do you see this fitting into current laboratory testing Links • Multicenter Evaluation of the Acuitas AMR Gene Panel for Detection of an Extended Panel of Antimicrobial Resistance Genes among Bacterial Isolates. https://journals.asm.org/doi/10.1128/JCM.02098-21 This episode of Editors in Conversation is brought to you by the Journal of Clinical Microbiology and hosted by JCM Editor in Chief, Alex McAdam and Dr. Elli Theel.

Ep 42COVID-19 Associated Pulmonary Aspergillosis - The Other CAPA (JCM ed.)
When most of us hear the word 'CAPA', these days we more than likely immediately start thinking about SARS-CoV-2 variants, trying to remember how important this particular one was in the grand scheme of the COVID-19 pandemic. But, that is not the 'kappa' we will be talking about today. Instead, we'll be discussing the other CAPA, or COVID-19 Associated Pulmonary Aspergillosis, and we will cover a few areas on this topic, including: - Defining what CAPA is and how prevalent it is among ICU patients with COVID-19 - Discuss why identification of invasive aspergillosis in patients with COVID-19 differs compared to other at-risk patients - Review two recent publication in JCM that discuss specific assays and diagnostic approaches for optimal detection of invasive aspergillosis in patients with COVID-19.

Ep 40Testing for COVID-19 During the Age of Omicron (JCM ed.)
In less than two months since it was discovered, the omicron variant of SARS-CoV-2 has become the dominant variant of the virus, causing an unprecedented rise in the number of cases of COVID-19 in the U.S. and elsewhere. The emergence of this variant has quickly led to some surprising claims about diagnostic testing for omicron and a renewed appreciation of the importance of sequencing the viral genome for typing purposes. We will address several questions about testing for omicron, including: • Are rapid antigen tests sensitive for detection of omicron? And should people swab their throats to increase the sensitivity of these tests? • How does the emergence of omicron change our use of polymerase chain reaction tests for SARS-CoV-2? • How can we definitively identify the omicron variant and do we have the needed capacity for this?

Ep 39Best Clinical Microbiology Papers of 2021 (JCM ed.)
As we round out yet another year of this pandemic, clinical microbiologists have not slowed down. We have not slowed down in our response to the pandemic or other day-to-day testing needs, despite the constant reagent backorders and personnel shortages, and equally as important, we have not slowed down in publishing high quality, informative and clinically relevant papers, which have really spanned the gamut of clinical microbiology - from antimicrobial susceptibility testing, to next generation sequencing assays and AI, to evaluation of new high throughput assays for a variety of pathogens, the field continues to expand at an impressive pace. Three Journal of Clinical Microbiology (JCM) editors discuss some of their favorite and most impactful papers published in the Journal in 2021. Welcome to Editors in Conversation. This episode is brought to you by the Journal of Clinical Microbiology, available at https://jcm.asm.org and on https://twitter.com/JClinMicro and is supported by the American Society for Microbiology, which publishes JCM.

Ep 37SARS-CoV-2 Sequencing for Clinical Care and Infection Control (JCM ed.)
Is sequencing the SARS-CoV-2 genome useful for patient care? What about institutional infection control? And if clinical labs decide to perform SARS-CoV-2 sequencing, how should they do it? How should they report the results? And will they get paid? Until recently, sequencing of SARS-CoV-2 genomes has mainly been done in public health or research laboratories. Now, there is increasing interest in sequencing the viral genome in healthcare settings for uses in patient care and infection control. We'll be talking about a new guideline that can help clinical labs and institutions decide whether to perform SARS-CoV-2 sequencing.

Ep 34Testing for COVID-19 Infectivity (JCM ed.)
How can we determine whether someone who has COVID-19 can transmit the virus to other people? Tests in routine clinical use, such as reverse-transcription polymerase chain reaction and antigen tests, are designed to determine whether SARS-CoV-2 is present or not, but many people have proposed that these tests be used to determine whether a patient is infectious. Furthermore, tests for SARS-CoV-2 that are not routinely used in clinical laboratories, such as viral culture and detection of sub-genomic viral RNAs, have also been discussed as indicators of infectivity. But how accurate are any of these tests for determining whether someone is infectious?

Ep 33Treatment of VRE Infections (AAC ed.)
Enterococci, particularly vancomycin-resistant isolates tend to affect the most vulnerable and immunocompromised patients and are one of the most difficult bacteria to treat. In absence of robust clinical data, we will discuss therapeutic approaches for these recalcitrant organism.
Ep 32Advances in Serologic Testing for COVID-19 (JCM ed.)
Tests for antibodies, or serological testing, for SARS-CoV-2 have come a long way since the early days of the COVID-19 pandemic. There are now several commercial tests available and some laboratories have developed tests for specific purposes. Tests can determine whether a person has had COVID-19 in the past, or whether someone has had an antibody response to vaccination or even whether someone has antibodies that can neutralize the virus, preventing it from infecting host cells. Guests: - Dr. Elitza Theel, Director of the Infectious Diseases Serology laboratory at Mayo Clinic in Rochester, Minnesota. - Dr. Alex Greninger, Assistant Director of the Clinical Virology Laboratory at the University of Washington Clinical Virology Laboratory, where he is also an Assistant Professor of Laboratory Medicine.

Ep 28Staphylococcus argenteus: another coagulase positive Staphylococcus (JCM ed.)
In addition to Staphylococcus aureus, there are a small number of other coagulase-positive staphylococci. We have become increasingly aware of these due to improvements in identification methods used in clinical laboratories. Staphylococcus argenteus is a coagulase-positive Staphylococcus that, until now, had mainly been detected in Australia, the Pacific Islands and Thailand. It was thought that the species might be geographically restricted, however a paper in the June issue of the Journal of Clinical Microbiology describes a large number of isolates collected from patients in North America. We'll be talking to two of the authors of this paper. Guests: Dr. Julianne Kus, Dr. Audrey Schuetz
β-lactam/β-lactamase inhibitor combinations (AAC ed.)

Ep 26Reconciling Genotypic and Phenotypic Susceptibility Tests (JCM ed.)
Our options for susceptibility testing have greatly increased in recent years. In addition to classical phenotypic susceptibility testing by disk diffusion and measurement of the minimum inhibitory concentration, genotypic tests are increasingly available. Genotypic tests range from tests for a single organism and one resistance gene to tests for 20 or more organisms and multiple resistance genes. But what should the clinical microbiologist do when the results of phenotypic and genotypic are in conflict? Welcome to Editors in Conversation. This episode is brought to you by the Journal of Clinical Microbiology, available at jcm.asm.org and on twitter @JClinMicro. I'm JCM Editor in Chief, Alex McAdam.

Ep 24Pandemic Built Environment (mSystems ed.)
During the pandemic researchers who focus on the microbiology of built environments suddenly found themselves at the center of attention. Understanding how SARS-CoV-2 may be spreading indoors became incredibly important to ensure we can operate indoors in a safe manner. We now know that SARS-CoV-2 transmits through the air in droplets and as particles, and this information has helped us to provide comprehensive advice on how people should manage the indoor environment. Last year my guests published a review in mSystems: 2019 Novel Coronavirus (COVID-19) Pandemic: Built Environment Considerations To Reduce Transmission. This is published with co-authors David A. Coil, Mark Fretz, and Jonathan A. Eisen. This paper was the most downloaded article for mSystems in 2020, and was in the top ten most downloaded articles across all ASM journals. This is maybe not surprising based on the topic covered.

Ep 21Optimizing Blood Cultures with Dr. Eric Ransom and Dr. Valeria Fabre (JCM ed.)
Blood cultures for bacteria and yeast are among the most clinically important and high-volume tests performed by clinical microbiology labs. Because these cultures are so important to clinical care, we want to make sure that blood cultures are performed as quickly and accurately as possible, and that they are ordered, collected and utilized appropriately. We are going talk about two recent papers. The first is about diagnostic stewardship for improving utilization of blood cultures and the second is about reporting blood culture results more quickly. Guests: Maria Valeria Fabre, M.D., Eric Ransom, Ph.D. Some of the questions we'll discuss include: • What steps can be taken to reduce the number of inappropriate blood cultures ordered in non-neutropenic adult patients? • Can the final results of blood cultures be reported earlier than the canonical 5 days?

Ep 19Susceptibility testing for Staphylococci Other Than S. aureus (JCM ed.)
Susceptibility testing for staphylococci other than S. aureus, or SOSA, has become increasingly complicated, as more laboratories use MALDI-TOF to routinely identify these bacteria to the species level. In particular, accurate identification of methicillin resistance has become more complex as the different species are distinguished by the accuracy of different susceptibility testing methods and breakpoints for interpreting MICs and zone sizes. Some of the questions we'll discuss include: What is the gold standard for detecting methicillin resistance in SOSA? How will the recommended breakpoints for detection of methicillin-resistant SOSA change? Why should we call these bacteria SOSA instead of coagulase-negative staphylococci? Guests: Dr. Romney Humphries, Dr. Lars Westblade Links mentioned: Evaluation of Surrogate Tests for the Presence of mecA-Mediated Methicillin Resistance in Staphylococcus capitis, Staphylococcus haemolyticus, Staphylococcus hominis, and Staphylococcus warneri The End of Coagulase-Negative Staphylococci?
