A female domestic shorthair cat recently adopted from the shelter was brought to her new veterinarian for a routine check-up. Fecal flotation revealed the egg below (shown in two different planes of focus). What parasite is this?
Case and photos provided by veterinarian and NCVP graduate resident Dr. Alice Lee, Cornell University.
Aonchotheca putorii eggs have characteristically deep striations on their shell surface. The adult worms are found in the stomach and small intestine of mustelids, raccoons, bobcats, and other mammals. Infection of domestic cats appears to be confined to the stomach and may cause gastritis.
