Parasites in tissue: how to identify the structures

January 2019—Pathologists who aren’t microbiologists can provide a diagnosis of parasitic disease if they take into account parasite life cycles and tissue tropisms. Julie A. Ribes, MD, PhD, made that key point in cases she presented in her CAP18 session, “Update on Invasive Parasitic Infections for Surgical Pathologists.” Dr. Ribes added learning material to most of the cases, she said, but the cases come from parasites she has seen and known in her own professional life.

Microbiology’s shifting role in war on sepsis

August 2018—If you were casting about for the severest test of a laboratory’s capabilities, day in and day out, sepsis admissions at a pediatric hospital might fit the bill. At Children’s Hospital of Philadelphia, and at other hospitals, waging war on sepsis requires battles on multiple fronts and clinical pathways that rely on an agile and highly equipped microbiology laboratory. Three main categories of patients ensure there is no shortage of sepsis cases at CHOP, says Erin H. Graf, PhD, D(ABMM), director of the infectious disease diagnostics laboratory.

TLA in, volume up—micro labs take stock

May 2017—Rise of the Robots. Disruption. Humans Need Not Apply. “The Future of Work.” A flood of books and articles in the past several months make the argument that service industries in the U.S. hover on the brink of total automation and humans will have to figure out how to adapt. Forty-five years ago, when Michael R. Jacobs, MD, PhD, started in microbiology, people fantasized about microbiology reaching this stage.

One bug or prix fixe? Respiratory pathogen testers weigh in

February 2017—With the number of rapid, accurate molecular assays for respiratory pathogens growing, microbiology laboratories have more options than ever. They include, among others, Meridian Bioscience’s Illumigene assays for group A Streptococcus and pertussis and its newest assay, Mycoplasma Direct, as well as Alere’s assays for influenza A/B, respiratory syncytial virus, and Streptococcus on its i molecular platform. No longer are laboratories limited to inaccurate rapid antigen tests, weeks-long culture, or multi-pathogen panels.

FilmArray GI: findings from first months of clinical use

April 2016—Treating Clostridium difficile can be dreadfully difficult, even when a clinician doesn’t have to navigate ordering restrictions based on testing frequency. So when Julie A. Ribes, MD, PhD, director of clinical microbiology at UK HealthCare in Lexington, Ky., received a phone call last year from a clinician who asked for repeat C. difficile testing, she was more than sympathetic.

Cutting cultures: the move to all molecular in virology

March 2016—For laboratories performing virology testing, taking advantage of molecular testing’s superiority to traditional testing methods is a no-brainer. But leaders in the University of Michigan’s clinical microbiology laboratory have found that the push to go all molecular for virology testing must be tempered by attentiveness to clinician preferences and a collaborative approach that’s likelier to make the journey a success.

For infection control, PCR and culture compared
Plus, an in-house PCR test for HSV in CSF

January 2016—There is a reason why rigorous studies are done to prove even the seemingly apparent benefits of advanced techniques. Sometimes comparisons turn up unexpected findings, as demonstrated by two selected infectious disease abstracts about real-time PCR presented at the Nov. 5–7, 2015 meeting of the Association for Molecular Pathology. Even so, both abstracts show the value of PCR testing.
