To provide hygienically correct milk it is necessary for mammary gland to be free bacteria which can lead to disorder in secretion, changes in quality and quantity of milk. One of the most significant causes of mastitis is Streptococcus agalactiae, which leads to chronic mastitis with latent clinical picture and seldom to acute mastitis. In certain percent of infected cows there are no significant changes in quality and quantity of milk and their milk meets quality standards. Animals that release bacteria with milk are reservoir of infection. We have isolated Streptococcus agalactiae from animals on four from total five farms. Average somatic cell count in infected cows was 219x10**3/ml to 1812x10**3/ml milk. Cows with findings of Streptococcus agalactiae in udder represent potential reservoir for spread of infection, because they can not be identified with additional tests for secretion disorder detection.
