奶牛乳房炎病畜生鲜乳中大肠杆菌污染状况及耐药性分析

为了解奶牛乳房炎病畜生鲜乳中大肠杆菌污染状况及耐药性,于2019年从潍坊、青岛采集牛乳房炎病畜生鲜乳样品共计98份,对其中常见大肠杆菌的污染状况进行分析。结果表明,98份奶牛乳房炎病畜生鲜乳样品中,42份检出大肠杆菌,检出率为42.9%。对检出的大肠杆菌菌株进行10种抗生素的药敏试验,结果表明,检出的大肠杆菌对氨苄西林、多西环素、四环素有较高的耐药性,且多数为多重耐药菌株。综上,牛乳房炎病畜生鲜乳中大肠杆菌污染较为严重,建议相关部门进一步加强牛乳房炎病畜生鲜乳的监管,采取针对性风险监测措施。

浅析奶牛乳房炎的危害及其发生规律与防治

奶牛乳房炎作为一种比较复杂的乳腺炎症，对奶牛养殖企业可能会带来很大的经济损失，这也是目前奶牛养殖企业面临的一种最为严重的一种疾病。就目前奶牛养殖业的实际情况来看，全球奶牛养殖企业的奶牛有1，3左右均患有不同类型的乳房炎，并且我国奶牛发生乳房炎的几率还要远远高于其他国家，这对牛奶的质量以及奶牛的产奶量均有较大的危害。同时奶牛乳房疾病在治疗以及预防方面的成本也较高、难度也较大。
