The agar dilution method was used to determine the activities of gentamicin, erythromycin, streptomycin, chloramphenicol, ampicillin, sulfamethazine, cephalothin, penicillin G, and tetracycline against 73 strains belonging to the genus Listeria (L. innocua, L. seeligeri, and L. monocytogenes). All strains were isolated from raw milk, cheese, the dairy processing plant, poultry, and the poultry slaughterhouse. Gentamicin, ampicillin, and erythromycin, of which the MICs for 90% of the strains tested for all three species were < or = 5.96 micrograms/ml, were found to be the most active agents studied. Most of the L. innocua strains isolated from poultry and the poultry slaughterhouse were resistant to tetracycline.
采用琼脂稀释法测定庆大霉素、红霉素、链霉素、氯霉素、氨苄青霉素、磺胺二甲嘧啶、头孢噻吩、青霉素G和四环素对73株李斯特菌属(无害李斯特菌、斯氏李斯特菌和产单核细胞李斯特菌)菌株的活性。所有菌株均分离自生牛奶、奶酪、乳制品加工厂、家禽及家禽屠宰场。庆大霉素、氨苄青霉素和红霉素对所有三个菌种90%测试菌株的最低抑菌浓度均≤5.96微克/毫升,是所研究的最具活性的药物。从家禽及家禽屠宰场分离出的大多数无害李斯特菌菌株对四环素耐药。
