The disk method with Ericson and Bauer's solid nutrient media were employed to ascertain the drug resistance of a total of 54 strains of Escherichia coli, 25 strains of Staphylococcus aureus, 11 strains of Streptococcus pyogenes, 7 strains of Corynebacterium pyogenes, 7 strains of Streptococcus uberis, 2 strains of Streptococcus agalactiae, and 1 strain of Streptococcus disgalactiae isolated from utero-cervical exudate and milk samples of sows with clinical symptoms of mastitis-metritis-agalactia (MMA). It was found that gentamycin only suppressed 100 per cent of the strains. So far as the other chemotherapeutic agents were concerned the organisms showed a varying extent of resistance. After determining the sensitivity of the strains to drugs two groups of pigs (from which the strains referred to were isolated) were subject to treatment. All 20 sows of the first group were treated with oxytocin only, while the 446 animals of the second group were treated with gentamycin in combination with oxytocin. It was found that effective therapy in the case of MMA was impossible with the application of preparations on the base of the hind lobe of the pituitary only. It is necessary to use chemotherapeutic means tow which the isolated organisms are susceptible.
采用埃里克森和鲍尔的固体营养培养基纸片法，对从患有乳房炎-子宫炎-无乳综合征（MMA）临床症状的母猪子宫颈渗出物和乳汁样本中分离出的54株大肠杆菌、25株金黄色葡萄球菌、11株化脓性链球菌、7株化脓棒状杆菌、7株乳房链球菌、2株无乳链球菌和1株停乳链球菌进行耐药性测定。结果发现，庆大霉素仅能抑制100%的菌株。就其他化疗药物而言，这些微生物表现出不同程度的耐药性。在确定菌株对药物的敏感性后，对两组（从中分离出上述菌株）猪进行治疗。第一组的所有20头母猪仅用催产素治疗，而第二组的446头动物用庆大霉素与催产素联合治疗。结果发现，仅使用垂体后叶制剂治疗MMA是不可能取得有效疗效的。有必要使用分离出的微生物敏感的化疗手段。
