In 1974, the State Veterinary institutes in the Slovak Socialist Republic studied the sensitivity of 4420 strains of Streptococcus agalactiae and 1056 strains of Staphylococcus aureus to eight antibiotics. The strains were isolated from milk samples obtained from dairy cows suffering from mastitis. 100 per cent of the strains of Streptococcus agalactiae was sensitive to ampicillin, 99.23% to erythromycin, 98.70% to oxytetracycline, 93.02% to bacitracin, 90.77% to chloramphenicol, 41.97% to penicillin, 12.39% to neomycin, 9.73% to streptomycin. As to the strains of Staphylococcus aureus, 98.68 were sensitive to chloramphenicol, 98.50% to ampicillin, 97.92% to erythromycin, 94.98% to oxytetracycline, 93.85% to neomycin, 92.67% to bacitracin, 87.50% to streptomycin, and 46.24% to penicillin. The results are discussed in relation to the use of antibiotics in the treatment of mastitis in dairy cows.
1974年，斯洛伐克社会主义共和国的国家兽医研究所研究了4420株无乳链球菌和1056株金黄色葡萄球菌对8种抗生素的敏感性。这些菌株是从患乳腺炎的奶牛的牛奶样本中分离出来的。无乳链球菌菌株对氨苄青霉素的敏感性为100%，对红霉素为99.23%，对土霉素为98.70%，对杆菌肽为93.02%，对氯霉素为90.77%，对青霉素为41.97%，对新霉素为12.39%，对链霉素为9.73%。至于金黄色葡萄球菌菌株，对氯霉素的敏感性为98.68%，对氨苄青霉素为98.50%，对红霉素为97.92%，对土霉素为94.98%，对新霉素为93.85%，对杆菌肽为92.67%，对链霉素为87.50%，对青霉素为46.24%。文中结合抗生素在奶牛乳腺炎治疗中的应用对结果进行了讨论。
