Abstract

Sheep and goat are important production sources of meat and milk in Egypt. Diarrhea is very common and the chronic form of it may lead to deaths, so the accurate diagnosis of fugal diseases causing diarrhea is a priority. In the current study, the fungal infections causing diarrhea in sheep and goats were investigated. From 200 examined samples; 27 yeast isolates (13.5%) and 112 mold isolates (56.00%) were recovered from the mycological examinations of the collected samples from diarrheic animals, contact workers and feed stuffs. A. flavus and Rhodotorula sp. were the most prevalent mould and yeast isolated from the examined samples, respectively. A. flavus and Rhodotorula sp. were molecularly identified using PCR tests. They showed clear bands at 305 bp molecular weight for A. flavus and 560bp for Rhodotorula sp. PCR is a useful method for diagnosing fungi that cause diarrhoea in sheep and goats in a direct and timely manner.
