LEVEDURAS EM CASOS DE MASTITE BOVINA SUBCLÍNICA NO SUL DO RIO GRANDE DO SUL

Abstract

Some foods such as milk plays an important role in the human diet, because it provides a number of essential nutrients. The contamination of milk by undesirable micro-organisms such as fungi, can cause physical and chemical changes in it, limiting its durability and its derivatives, as well as determining economic and public health problems. Yeasts are the etiologic agents most often related to infections of the mammary gland in dairy cattle. For this work, they collected 640 milk samples coming from the mammary glands of lactating cows that showed positive result to the California Mastitis Test (CMT). It was previously held disinfecting ceiling swab 70ºGL alcohol, samples were gathered, about 10 ml of milk and these were referred to Mycology Laboratory in UFPel Institute of Biology and seeded in Petri plates containing Sabouraud Dextrose Agar Chloramphenicol added and stored in the greenhouse for 7 days at 36 °C. In the samples in which there was yeast growth, made the identification using the Vitek 2 system. The following were identified: Cryptococcus laurentii, Candida famata and Candida parapsilosis.
