A total of 455 streptococcal cultures from bovine intramammary infection in 72 herds were studied to determine their sensitivity to 17 antimicrobial agents. More than 90% of the cultures were sensitive to carbenicillin, chloramphenicol, erythromycin, and penicillin. Gentamicin, neomycin, nitrofurazone, polymyxin, and streptomycin were ineffective in the in vitro inhibition of streptococci.
对来自72个牛群的455份牛乳房内感染链球菌培养物进行了研究，以确定它们对17种抗菌剂的敏感性。超过90%的培养物对羧苄青霉素、氯霉素、红霉素和青霉素敏感。庆大霉素、新霉素、呋喃西林、多粘菌素和链霉素在体外对链球菌的抑制作用无效。
