title: A contribution to the research of infection of cows and humans with Streptococcus agalactiae.
abstract: In the small area of eight alpine villages in Slovenia 159 cows and 113 persons from 34 family-farms on Streptococcus agalactiae (Str. agal.) were examined. From the milk of 35 cows (22%) from 21 farms and from the throat and urine of 17 persons (15%) from 14 farms Str. agal. was isolated. Identical serotypes of Str. agal. were established on the farms, where infected cows and infected persons were detected: in cows serotypes II and III and in persons serotypes II, III and R. In persons from the farms, where the cows were negative, other serotypes were found: Ib, Ic and II. In 12 persons Str. agal. was isolated from urine, in 3 persons from the throat and in 2 persons from the urine and throat. All positive persons were without visible clinical symptoms. We suggest, that one of the ways of infection with Str. agal. in humans is probably a direct route with infected milk or from the infected cows.
