Parasite Wonders: A parasitologist’s view of the world

August 29, 2017

a collage of images of unidentified parasites from the Parasite Wonders blog

This week's case involves a parasite whose appearance differs depending on the stains and preparations of the slides. These images — all from stool — are shown at 1,000 times original magnification, and the treatments are:

  • A - Wet preparation
  • B - Iodine-stained wet preparation
  • C - Trichrome stain
  • D - Wright Giemsa
  • E - Modified acid fast
  • F - Modified safranin

What is it?

Every week, Dr. Bobbi Pritt, a Mayo Clinic microbiologist, posts a new case, along with the answer to the previous case. Read Dr. Pritt's blog, Creepy, Dreadful, Wonderful Parasites, and submit your answers, comments and questions. Learn more about Dr. Pritt's work, and enjoy science!
