Abstract
Samples of cervico-vaginal mucus from 633 animals from 110 herds were cultured and yielded the following mycoplasmas: T-strain--88: Mycoplasma bovigenitalium--79, Mycoplasma spp. (Leach Group 7)--7, Acholeplasma laidlawii--4, Mycoplasma bovirhinis--2 and one not typable. Uterine exudates and endometrial scrapings from 80 infertile cows in two herds were examined. Four animals were positive, M. bovigenitalium was isolated three times, A. laidlawii and Mycoplasma arginini once each. Sixty-five normal uterine contents from pregnant cows were examined, one yielded M. bovigenigalium and the same organism was recovered from the fetal kidney. T-strain mycoplasma, M. bovigenitalium and other Mycoplasma spp. appear to be a part of the normal flora of the cervico-vaginal region of clinically normal one and two year old bred heifers in Alberta and Saskatchewan. Although M. arginini was not recovered from the cervico-vaginal region, a single recovery was made from the uterus of an infertile cow.
