This is the first report documenting the presence of a high number of Cyniclomyces guttulatus yeasts in the faeces of a cat. The animal was initially presented with acute complaints of vomiting and diarrhoea. The patient responded well to oral salazosul-fapyridine but the stools remained soft and C. guttulatus yeasts were still present. After a course of nystatin (15,000 IU/kg bw q24 PO for 4 days) the stools were normal and no yeasts were found anymore (centrifugation/flotation/zinc sulphate). C. guttulatus occurs naturally in the digestive tract of rabbits, guinea pigs, chinchillas, rats and mice. It is occasionally found in massive numbers in the faeces of dogs with diarrhoea; part of these patients respond well to nystatin treatment. Recent experience indicates that the most effective dosage of nystatin for dogs and cats is 50.000 IU/kg q24 PO for 4 days.

Domestic rabbits are commercially farmed for their meat whilst gastrointestinal diseases can hinder their production. and spp. are two common rabbit intestinal parasites that can cause diarrhoea, among other symptoms, and in severe cases, death.

Laboratory confirmation of the causative agent(s) of diarrhoea in puppies may allow for appropriate treatment. The presence of potential pathogens however, does not prove a causal relationship with diarrhoea. The aim of this study was to identify specific enteropathogens in ≤12 month old puppies with and without acute diarrhoea and to assess their associations with clinical signs, putative risk factors and pathogen co-occurrence.

Cyniclomyces guttulatus, a gastrointestinal yeast of rabbits, is considered an uncommon, nonpathogenic, "pass through" organism and possible opportunistic pathogen in dogs that consume rabbit feces. This retrospective study aimed to characterize the presenting complaint, clinical findings, location of organisms, and final diagnosis of dogs in which yeast morphologically consistent with C. guttulatus were identified at a veterinary teaching hospital from 2006-2013.
