【摘要】 [目的]为了准确高效防治牛子宫内膜炎。[方法]对30头病例的病原菌分离与药敏试验,结果从30头患畜子宫分泌物中分离鉴定出3种主要致病菌,其中疑似葡萄球菌14株,阳性率为46.7%(14/30);疑似链球菌11株,阳性率为36.7%(11/30);疑似大肠杆菌5株,阳性率为16.7%(5/30)。[结果]表明:恩诺沙星、卡拉霉素、诺氟沙星的抑菌效果明显,可视为目标场治疗子宫内膜炎的首选药物。而链霉素、青霉素的抑菌效果相对较差,可能与其长期使用这些药物而产生耐药性有关。[结论]用药时需合理配伍,不随意加大剂量,同时几种药物交替使用,以免产生耐药菌株,影响治疗效果。更多还原

【Abstract】 【Objective】Cattle endometritis is a common and frequently-occurring disease,which majorly affects the conception rate in dairy cattle farm.The objective of this study is to prevent and cure cattle endometritis accurately and efficiently.【Method】Pathogens were separated from 30 dairy cattle that suffered from endometritis and were analyzed by medicine sensitive test.The results showed that the uterine secretion derived pathogens included three major kinds of bacterias:14strains of suspected Staphylococcus aureus(positive rate is 46.7%),11 strains of suspected Streptococcus(positive rate is 36.7%),5strains of suspected Escherichia coli(positive rate is 16.7%).【Result】Based on the medicine sensitive test,it showed that enrofloxacin,kalamycin,norfloxacin may observably inhibit the growth and proliferation of pathogens and may be the primary candidate for endometritis therapy in dairy cattle farm.However,the pathogens were insensitive to streptomycin and penicillin.It suggested that drug-resistant generated and may due to long-term use of these antibiotics.【Conclusion】As a conclusion,to avoid drug-resistant and maximize the therapeutic efficacy,compatibility of medicines should be applied in a reasonable ratio and the dosage should be controlled and should not be increased casually.Meanwhile,different kinds of medicine should be used alternately.更多还原
