牛病毒性腹泻(Bovine viral diarrhea, BVD)是一种呈世界性分布,并且对畜牧业造成巨大经济损失的疾病.BVDV是黄病毒科瘟病毒属的一员,可分为BVDV-1型和BVDV-2型.研究证明,BVDV会引起牛的急性感染、持续感染(Persistent infection,PI)和黏膜病(mucosal disease,MD),损害牛的生殖系统和免疫功能,引起发热、腹泻、溃疡、不孕、流产、死胎、免疫抑制等,从而造成严重的经济损失.目前研究结果表明,多种多样的临床症状都和BVDV感染存在一定的关系.即使是免疫功能健全的奶牛表现为瞬时感染,但当其他病原微生物感染的前提下,BVDV可以加重其感染的程度,并表现出明显的临床症状.

金黄色葡萄球菌是奶牛乳房炎中常见的感染性病原菌,由其引发的乳房炎给奶牛养殖业造成了巨大的经济损失.为了指导临床合理使用抗生素治疗金黄色葡萄球菌性乳房炎,该研究通过K-B纸片法从临床型奶牛乳房炎乳汁中分离鉴定了39株金黄色葡萄球菌,并进行了药敏实验.结果显示,金黄色葡萄球菌对青霉素的耐药性较强,其耐药率达到了89.5％；其次是红霉素和四环素,耐药率分别为28.9％和21.1％；对庆大霉素、卡那霉素、
