About Bobbi Pritt

I'm a AP/CP trained pathologist with a special love for all things infectious. My favorite organisms are parasites, and that is the focus of my clinical practice. I did my pathology residency at the University of Vermont (great program), and then a one-year fellowship in Clinical Microbiology at Mayo Clinic, Minnesota. I then was fortunate enough to spend a year in London at the London School of Hygiene and Tropical Medicine on a scholarship, where I got a Diploma in Tropical Medicine and a Masters degree in Medical Parasitology. My favorite things to do are teaching, writing, directing the Clinical Parasitology Laboratory, and compiling cases for an Atlas that I hope to publish in 2010. I love to collaborate with like-minded investigators, and am always looking for new parasite cases for the Case of the Week. Please feel free to write in and share your comments, questions, and cases with me!

Answer to Case of the Week 59

Answer, Part I: Trichinella spp. Although Trichinella spiralis is the most common species to infect humans in the United States, it is generally not possible to speciate based on morphologic features.
