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.
진주근교에서 효모균에 의한 젖소의 준임상형 유방염 발생상황과 이들균의 유두컵내의 오염상태를 조사하였던 결과는 다음과 같다. 총 검사분방 330개 중 12분방으로부터 효모균이 분리되어 이로인한 준임상형 유방염의 발생율은 3.6%이었다. 분리균 12주는 Candida pseudotropicalis 4주, C tropicalis 3주, C krusei 2주, C albicans 2주 및 Rhodotorula spp 1주로 동정되었으며, 분리균의 91.7%가 Candida속 균이었다. 유두컵 200개 중 20.5%로부터 C. pseudotropicalis 13주, C guilliermondii 9주, C tropicalis 7주, C krusei 5주, C parapsilosis 5주, C albicans 3주, Torulopsis glabrata 2주, Geotrichum candidum 2주 및 미동정 효모균 5주가 분리되었다.
