For this post, I wanted to highlight one of the fabulous cases from Tulane University, the former lab of the Parasite guru, Thomas Orihel. I had the pleasure of putting on a Parasitology workshop last week at the ASTMH annual meeting along with Christina Coyle, Michael Libman, and Susan McLellan; Susan is an infectious disease physician at Tulane and was our host for the workshop.
The following is one of the coolest displays I've ever seen - back from the 1950s when tapeworms were submitted following treatment (often with quinacrine) to ensure that the head was expelled. On an interesting historical note, quinacrine is not thought to have vermicidal activity, but causes the head to detach so that the worm can be expelled. Its use has now been replaced by praziquantel and other more effective medications for treatment of cestode infection.
