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.

SARS-CoV-2 Sequencing for Clinical Care and Infection Control (JCM ed.)

Editors in Conversation is the official podcast of the American Society for Microbiology Journals. Editors in Conversation features discussions between ASM Journals Editors, researchers and clinicians working on the most cutting edge issues in the microbial sciences. Topics include laboratory diagnosis and clinical treatment of infectious diseases, antimicrobial resistance, epidemiology of infections, multidrug-resistant organisms, pharmacology of antimicrobial agents, susceptibility testing, and more.

The podcast is directed to microbiologists, infectious diseases clinicians, pharmacists and basic, clinical and translational researchers interested in the microbial sciences. A particular emphasis is on basic, epidemiological and pharmacological aspects of infectious diseases, including antimicrobial resistance and therapeutics.

Rhodococcus infections are uncommon, however they can cause serious disease in certain patients. There are a number of challenges though when dealing with Rhodococcus infections, including the fact that much of what we know around their susceptibility profiles and the clinical management of infected individuals actually comes from a number case series and in some situations, from the veterinary literature.  So today, our two guests are going to tell us about their experiences with Rhodococcus over a 10-year period and bring us up-to-speed on things like:    Which species of Rhodococcus are most commonly isolated and associated with clinical disease What is the recommended approach to susceptibility testing for Rhodococcus and what sorts of susceptibility trends do we see at both the genus and species levels And also, of course, we’re going to talk about the clinical manifestations and outcomes of clinically significant Rhodococcus infections  Guests:  Adi S. Shah, M.B.B.S., Mayo Clinic Nancy L. Wengenack, Ph.D., Mayo Clinic  Related article: Rhodococcus infection: a 10-year retrospective analysis of clinical experience and antimicrobial susceptibility profile | Journal of Clinical Microbiology  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.

10 Years of Rhodococcus: Clinical Trends and Susceptibility Profiles

Phage therapy has gained a lot of traction but the challenges created by this approach have not been properly assessed at a big scale. We often read about therapy successes on isolated cases but, rarely, we read or hear about failures. AAC recently published a case series of patients who failed phage therapy. Today, we will discuss this topic with the principal investigator on the research. Topics discussed:  Phage therapy as an approach for MDR bacteria. The challenges of phage therapies. Issues that can influence the success of phage therapy  Guest:  Saima Aslam, MBBS. Director, Solid Organ Transplant Infectious Diseases Service, Professor of Medicine, University of California, San Diego.  Article: Pseudomonas aeruginosa ventricular assist device infections: findings from ineffective phage therapies in five cases https://journals.asm.org/doi/10.1128/aac.01728-23 Questions Answered:  How are we doing with phage therapy at this point? What are the challenges to deploy phage therapy in clinical settings? The 5 cases of failure of phage therapy in patients with LVADs summarized What factors did Dr. Aslam identify that were related with the failure? How do you develop neutralization against phages and how can you prevent it?   Bacterial isolates with varying phage susceptibility, how can this be detected? What did Dr. Aslam learn? Future research  This episode is brought to you by the Antimicrobial Agents and Chemotherapy journal available at aac.asm.org.

Why Phage Therapy May Fail

The protozoan Lophomonas has been reported to be a pathogen of humans in a large number of case reports and case series. Most of these case reports describe infections of the respiratory tract. Editors in Conversation is joined by two experts to discuss this possible parasite.  Some of the questions addressed include:  What are the characteristics of the species in the genus Lophomonas? What are the laboratory and morphological data that suggest that Lophomonas species cause human infections? What are the purported clinical manifestations of Lophomonas? Finally, is Lophomonas truly a pathogen of humans?  Guests:  Dr. Abhishek Mewara - Additional Professor in the Department of Medical Parasitology at the Postgraduate Institute of Medical Education and Research in Chandigarh, India. Dr. Bobbi Pritt - Chair of the Division of Clinical Microbiology and Professor of Laboratory Medicine and Pathology at Mayo Clinic.

Is Lophomonas a Pathogen?

Tuberculosis is one of the most deadly infectious diseases that still causes significant burden of disease, particularly in the developing world.  The emergence of resistance to first line agents severely limits the therapeutic options and threaten the ability to control dissemination of this disease. Fortunately, new drugs and regimens are now emerging as important alternatives against these organisms.  Today, we will discuss this topic with outstanding experts in the field. Welcome to the editors in conversation. Topics discussed:  The burden of multidrug-resistant TB. New drugs and regimens for MDR TB. The current and future pipeline for TB  Guests:  Kelly Dooley, MD Ph.D.  Professor and Addison B. Scoville, Jr., Chair in Medicine, Director, Division of Infectious Diseases, Department of Medicine, Vanderbilt University Medical Center.

Treatment of Multidrug-resistant Tuberculosis

A new generation of B-lactamase inhibitors is likely to reach the market in the upcoming year. These broad-spectrum inhibitors exhibit activity against the most feared class B metallo-B-lactamases maintaining the inhibition of other enzymes. Recently AAC has published three papers that describe the mechanistic bases of taniborbactam resistance among metallo-enzymes. This knowledge is crucial to understand the limitation of these compounds in clinical practice. Today, we will discuss this topic with some of the authors of the mentioned papers. Welcome to the editors in conversation. Topics discussed:  The activity and chemical basis of new generation B-lactamase inhibitors with activity against metallo-B-lactamases. Taniborbactam as an example of novel B-lactam, B-lactam inhibitors Mechanisms of resistance to taniborbactam and other inhibitors  Guest:  Robert Bonomo, MD.  Director of the VA CARES Center and Distinguished Professor at Case Western Reserve University (CWRU) School of Medicine.
