BulgarianNurse ,

I love it!!

I am a nursing student and i am fascinated by microbiology and infectious diseases. Thank you for having this amazing resource for free!

rhods ,

Great show. Might need a new title though

Shouldn’t a monthly show be called This Month in Parasitism?

chemimen ,

A fun part of every month

I came to this podcast as a joke I played on a friend who had a nasty parasitic infection but stayed for the wit and wisdom. I have so much fun listening and studying, I hope you have as much fun making it as I do listening
