[Etiology of mastitidos in dairy cows in Slovakia during 1975].
In 1975, in the veterinary institutes in Slovakia bacteriological examinations of 54824 samples of milk coming from 28737 dairy cows were performed. Bacterial germs responsible for the inflammation of the mammary gland were found in the milk of 18.91% of cows. These were: Streptococcus agalactiae (in 13.93% of cows), Staphylococcus aureus (2.86%), other streptococci (1.32%), E. coli (0.13%), Klebsiella sp. (0.13%), Corynebacterium pyogenes (0.15%), other bacterial germs (0.39%). Streptococci and staphylococci, taken together, represented 95.83% of all bacterial germs, Streptococcus agalactiae representing 73.72%. In comparison with the situation existing in 1974, a drop was found in the occurrence rate of the germs of Streptococcus agalactiae (by 2.94%) and Staphylococcus aureus (by 1.16%).
