The antimicrobial susceptibility was determined for 50 Streptococcus uberis, 42 S. dysgalactiae subsp. dysgalactiae and eight S. agalactiae strains isolated from cow mastitis. Only 27% of the strains were susceptible to all antimicrobial compounds tested. Resistance to tetracycline was most frequent (particularly for S. dysgalactiae strains), then macrolide and/or lincomycin resistance. High level resistance to streptomycin and kanamycin was detected. All S. dysgalactiae and S. agalactiae strains were susceptible to beta-lactams but 44% of the S. uberis strains showed an elevated penicillin G MIC. All strains were susceptible to chloramphenicol and rifampicin.
对从奶牛乳腺炎中分离出的50株乳房链球菌、42株停乳链球菌停乳亚种和8株无乳链球菌进行了药敏试验。仅27%的菌株对所有测试抗菌化合物敏感。对四环素的耐药性最为常见（特别是停乳链球菌菌株），其次是大环内酯类和/或林可霉素耐药性。检测到对链霉素和卡那霉素的高水平耐药性。所有停乳链球菌和无乳链球菌菌株对β-内酰胺类敏感，但44%的乳房链球菌菌株显示青霉素G的最低抑菌浓度升高。所有菌株对氯霉素和利福平敏感。
