Plain-English summary

A 1-year-old male Maine Coon cat was brought in for persistent diarrhea that had lasted for nine months. After testing, the vet discovered the cause was a parasite called Enterocytozoon bieneusi. The cat was treated with albendazole for 10 days, followed by fenbendazole for 5 days, which successfully resolved the diarrhea. This case shows that certain parasites can cause long-term digestive issues in cats and highlights the importance of proper diagnosis and treatment.

Abstract

Enterocytozoon bieneusi, also known as microsporidia, is an obligate, opportunistic, and neglected intracellular pathogen that causes diarrhea in humans. Although identified in the cat feces by epidemiological studies, no association with diarrhea has been demonstrated. We demonstrated a case of chronic enteritis by E. bieneusi in a 1-year-old male Maine Coon cat, neutered with diarrhea for nine months, by histopathological analysis of gastrointestinal biopsies and PCR of feces. The treatment with albendazole (10 days) followed by fenbendazole (5 days) proved to be effective and safe after diagnosis. This description highlights the need to investigate these pathogens in cases of diarrhea due to their importance in public health since they are zoonotic agents.
