The results of antibiotic tests on bacterial pathogens freshly isolated from avian tissues and bovine milk are presented. Coliform isolates from the avian species showed an increased resistance to antibiotics while those which produced bovine mastitis had remained generally more sensitive. The staphyloccoci and streptococci isolated from bovine milk showed an increase in resistance to most of the antibiotics tested. The indiscriminate administration of antibiotics to livestock and poultry has no doubt encouraged the development of resistant forms of bacteria and has made treatment with such products less effective.
本文展示了对从禽类组织和牛乳中新鲜分离出的细菌病原体进行抗生素测试的结果。从禽类分离出的大肠菌群对抗生素的耐药性有所增加,而导致牛乳腺炎的菌群总体上仍更敏感。从牛乳中分离出的葡萄球菌和链球菌对大多数测试抗生素的耐药性有所增加。对畜禽不加区分地使用抗生素无疑助长了耐药菌的产生,也降低了此类产品的治疗效果。
