Popis: The role of non-specific bacteria in the infertility of clinically normal repeat-breeder cows is reviewed, and data are presented from a recent study in which bacteriological and histological samples were taken from the uteri of dairy cows at intervals during the non-gravid period. The evidence does not support the view that endometritis is an important cause of this infertility. In the absence of accurate counts of the bacteria present in the uterus at the time of service and during the subsequent oestrous cycle, it is impossible to determine whether pathogenic bacteria cause the infertility by injuring the gametes or the developing conceptus. A comprehensive quantitative study is needed of the microbiology of the uterus of the repeatbreeder cow at service and during the subsequent oestrous cycle.
