Creepy, Dreadful, Wonderful Parasites

Every week, Mayo Clinic microbiologist Bobbi Pritt, M.D., posts a new case, along with the answer to the previous case. 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. Note from Dr. Pritt: All opinions expressed here are mine and not my employer's. Information provided here is for medical education only.
