Background: Candidiasis is a fungal infection that is often caused by Candida albicans (C. albicans) and in a few cases caused by other Candida species. Infection of gastrointestinal tracts including mouth, esophagus and stomach, as well as enteritis and diarrhea are the most common form of the disease in cattle. Clinical findings: In January 2015 reduction in milk production and severe watery diarrhea were observed in a dairy farm located in Varamin city Tehran, Iran. So that 57.1% of cows with high milk production efficiency and 40% of cows with low milk production efficiency involved severe watery diarrhea. Laboratory tests: in clinical examination of affected animals vital signs such as number of breathing, heart rate, as well as the quality and number of ruminal movements were quite normal. No unusual sings were seen in CBC pattern of affected animals. In stool samples of affected animals no viruses or bacteria were detected while specimens were positive for yeast contamination RapID commercial kits used to identify the genus and species of yeast and C. famata was diagnosed as the cause of diarrhea. Final evaluation: Reports of diarrhea caused by fungal pathogens in animals is very low and Candida species, especially C. albicans and C. glabrata are known as the main causes of fungal diarrhea in animals .This study is the first repot about occurrence of C. famata diarrhea in adult cattle. So that C.famata could be considered as one of the potential causes of diarrhea in cattle.
