Abstract

The prevalence of yeasts in mammary glands of dairy cows and teat cups of milking machines was studied in Chinju area. The rate of subclinical yeast infection in 330 quarters was 3.6%. Of 12 isolates from the milk, 4 Candida pseudotropicalis, 3 C tropicalis, 2 C krusei, 2 C albicans and 1 Rhodotorula spp were identified. The 91.7% of the isolates belonged to the genus Candida and C pseudotropicalis was the predominant species. From 20.5% of 200 teat cups tested, 51 strains of yeasts were isolated. These were 13 C pseudotropicalis, 9 C guilliermondii, 7 C tropicalis, 5 C krusei, 5 C parapsilosis, 3 C albicans, 2 Torulopsis glabrata, 2 Geotrichum candidum and 5 unidentified yeasts. C pseudotropicalis was most frequently encountcred.
