Happy New Year! Here's a great case to start off 2022. A large structure (~25 cm-long) submitted to the Clinical Parasitology lab (found in stool). Identification?
A whole bundle of Ascaris lumbricoides. With this many, definitely there has to be females to produce that many, and this aggregate may have a majority of females and a few males mixed in. Most cases with only male, the number of round worm submitted is only one. Florida Fan
