Yeasts in the mammary environment of the cattle in the region of Sidi Mhammed Ben Ali, Wilaya of Relizane, Algeria

Abstract

Mastitis is one of the principal pathologies in the dairy bovine exploitation. Most of the cases are caused by bacteria, but some are caused by fungi. The objective of our study was to evaluate the occurrence of these fungi in mammary glands of 39 cows (mastitic and clinically healthy cows) belonging to two farms (four exploitations using manual milking and three exploitations using milking machine) in the area of Sidi M'hammed Ben Ali, Wilaya of Relizane and to assess some risk factors (the tubes of drug, animal excretion, goblets-milkers, the milkers' hands and the litter). For this purpose, 150 samples of milk and 94 swabs were used. Our results reveal the presence of a heavy load of fungi cells in healthy and mastistic milks, with a strong frequency of Trichosporon sp. (43, 58%) followed by Candida sp. (30.76%). The same yeasts were isolated from swabs.
