Intrapapillary deposition of 5-30 CFU into 7 lactating quarters of 6 cows resulted in clinical mastitis in all. Identical streptococci were subsequently recovered from 6 of the affected quarters. Details of milk somatic cell counts, bacterial isolation and clinical findings are tabulated. The role of GBS in human medicine and the implications of proof that the bovine udder is susceptible to small numbers of GBS from human sources are discussed.
