[Relationship between infections of the genitalia and udder in cows]

It was found that the pathogenic and occasionally pathogenic bacteria were readily transmitted in cows, originating from the genital tract, and more specifically from the uterine and vaginal discharge to the udder through the lactogenic route. The study of a total of 183 metritis-affected cows for the presence of Streptococcus uberis revealed that the pathogen could be found in the genital tract and in the udder in 20.7 per cent of the investigated cows, and it could be isolated simultaneously from the two organs in 82.6 per cent of the cases. In another group of cows also affected with metritis the study for the presence of different bacterial agents established coincidence in their simultaneous isolation from the uters and the udder in 61.2 per cent of the cases.
