Creepy, Dreadful, Wonderful Parasites

Case Studies

Mayo Clinic microbiologist Bobbi Pritt, M.D. started a blog, Creepy, Dreadful, Wonderful Parasites, 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. 

Every week, Dr. Pritt posts a new case, along with the answer to the previous case. Readers can submit answers, comments, and questions. The blog hosts an archive of classic images from cases she has posted going back to 2007 (in an easy-to-search "A through Z" format) and also offers a flashcard feature.
