Every week, Mayo Clinic microbiologist Bobbi Pritt, M.D., posts a new case, along with the answer to the previous case. Read Dr. Pritt's blog, Parasite Wonders, and submit your answers, comments, and questions. Also, visit her new website ParasiteWonders.com, which hosts an archive of classic images from cases Dr. Pritt has posted going back to 2007 (in an easy-to-search "A through Z" format) and also offers a flashcard feature.

Dr. Pritt started her blog after she completed her fellowship at Mayo Clinic in clinical microbiology. She attended the London School of Hygiene and Tropical Medicine to study parasitology for one year. During that year in England, Dr. Pritt saw some amazing cases, which she shared with her colleagues back at Mayo through her blog. Through word of mouth, people from all walks of life around the globe have become interested in Dr. Pritt’s “case of the week,” and her readership continues to grow.
