摘要
对湘西北地区某猪场患病的仔猪的粪便及病变的脾脏、肝脏、淋巴结、肺脏、肾水肿液进行病原菌分离鉴定,并用Kirby-Bauer法测定分离菌株对15种抗菌药的敏感性。结果表明,患病仔猪分离到大肠杆菌和猪葡萄球菌两种细菌。其中大肠杆菌对庆大霉素、头孢呋肟、丁胺卡那霉素、四环素、先锋必素敏感,对氯霉素、氧哌嗪青霉素、先锋五号、头孢曲松钠、新霉素中介,对羧苄青霉素、强力霉素、青霉素、氨苄青霉素、红霉素有较高的耐药性。葡萄球菌对先锋霉素Ⅴ、丁胺卡那霉素敏感,对头孢曲松钠中介,对其他抗生素耐药。其中大肠杆菌对药物敏感率、中介率、耐药率均为33.33%;葡萄球菌的敏感率为13.33%,中介率为6.67%,耐药率为80.00%。
The pathogen were isolated and identified on feces of sick piglets and disease of the spleen,liver,lymph nodes,lung,kidney edema fluidin a pig farm in Hunan northwestern region.Susceptibility of 15 kinds antimicrobial drug was determined with the Kirby-Barer for isolated strains.The results showed piglets were infected with E.coli-based and Staphylococcus.Escherichia coli was sensitive to gentamicin,cephalosporins latter skin,Amikacin,tetracycline,cefoperazone sodium,to chloramphenicol,piperacillin,pioneer V,ceftriaxone,neomycin was intermediate,to carbenicillin,doxycycline,penicillin,ampicillin,erythromycin had a higher resistance.Staphylococcus was sensitive to pioneer V,Amikacin,to ceftriaxone was intermediate,on the other antibiotic was resistance.Which was 33.33% the rate of drug sensitivity,intermediate and resistance to E.coli.Which was 13.33% sensitive rate,intermediate rate was 6.67%,resistance rate was 80.00% to Staphylococcus.
