Enzymatic activity of yeast species isolated from bovine mastitis

Fungal mastitis in cows is an increasing issue. The aim of the examination was to evaluate the species and enzymatic activity of yeast-like fungi from mastitis in cows. One hundred and twenty-six strains isolated from secretions of clinically and subclinically inflamed quarters of 102 cows were tested with the use of API 20 C AUX and then 63 strains were examined for enzymatic activity (API ZYM). Candida inconspicua (34.9% ), C. kefyr (19.9% ), C. krusei (11.1%) and S. cerevisiae (10.3%) were the mostly isolated species. Yeast from bovine mastitis showed activity of 12 enzymes, but alkaline phosphatase, valine arylamidase, acid phosphatase and Naphthol-AS-B1-phosphohydrolase were stated at the highest level.
