Abstract
Yeasts were isolated from 18 (11.3%) of 158 quarters with clinical mastitis and 14 (12.7%) of 110 quarters with subclinical mastitis. Three genera; 5 species and 18 strains (C. krusei, D. hansenii, etc.) were isolated from the former 18 quarters. Their count level was 10-1.4×104 per ml. Three genera, 5 species and 14 strains (C. tropicalis, C. rugosa, ect.) were isolated from the latter 14 quarters. Their count level was 10-7.2×103 per ml. Yeasts were isolated with Staphylococcus aureus, Streptococcus spp. from clinical mastitis, but not from subclinical mastitis. The isolated Yeasts were quite sensitive to Clotrimazole in Vitro.
