Biliary Coccidiosis in a Ferret ( <i>Mustela putorius furo</i> )

Abstract

This report documents the first case of biliary coccidiosis in the ferret. Multiple life stages of a coccidian parasite, including meronts, gametocytes, and oocysts were present in the epithelium of hepatic bile ducts and the gallbladder. Based on morphologic characteristics, the organisms were identified as Eimeria sp., most likely E. furonis.
