Plain-English summary

A cat with ongoing diarrhea was found to have a mixed infection of two types of parasites called Cryptosporidium muris and Cryptosporidium felis. Despite several treatments, the diarrhea did not improve, indicating that this infection can be challenging to resolve. This case highlights the need for more research on how these parasites affect cats and how common they are.

Abstract

To date Cryptosporidium muris has been identified by microscopy and genotyping in cats in two studies. We report morphological and genetic evidence of a mixed C. muris and C. felis infection in a cat and provide the first histological, immunohistochemical, in situ hybridisation and genetic confirmation of a C. muris infection in the stomach of a cat. The cat suffered persistent diarrhoea after the initial consultation, which remained unresolved, despite several medical interventions. Further studies are required to determine the range, prevalence and clinical impact of Cryptosporidium species infecting cats.
