The distribution and characterization of group B streptococci in New York State.
Group B streptococcal isolates from bovine mastitis were classified according to the Lancefield typing scheme. Three types were found in New York State dairy herds; Ia, II and III. The distribution within these types varies from area to area, however, on a state-wide basis Ia is the most prevalent (69.6%) followed by type II (16.7%) and type III (10.1%). Within a single herd one type predominants with only slight incidence of other types. Attempts to determine distinguishing characteristics between isolates of human and bovine origin resulted in no entirely consistent differences.
