摘要
从送检的20份疑似链球菌病病死猪病料中分离出10株细菌,根据培养特性、染色特点、形态观察及生化试验鉴定为链球菌。对分离到的10株链球菌进行了18种抗革兰阳性抗菌药物的药敏试验,结果A猪场4个分离菌株对复达欣、多黏菌素、头孢噻吩高度敏感,对青霉素、氨苄青霉素、红霉素、氟哌酸、环丙沙星以及阿莫西林表现出明显耐药性;B猪场6个分离菌株对头孢噻肟、复达欣、利福平、多黏菌素高度敏感,对青霉素、氨苄青霉素、红霉素、复方新诺明、氟哌酸、环丙沙星有明显耐药性。动物试验表明10株猪链球菌对小鼠均有致病性。
According to the cultural and staining characteristics,morphology and biochemical tests,10 strains of Streptococcus suis were isolated and identified from 20 samples of sick and dead pigs.18 kinds of anti-Gram-positive bacterial drugs were used for drug sensitivity tests for the isolated 10 strains.Results showed that the 4 strains from pig farm A were highly sensitive to fortum,polymyxin and cefalotin,and highly resistant to penicillin,ampicillin,erythromycin,norfloxacin,ciprofloxacin and amoxicillin;the 6 strains from pig farm B were highly sensitive to cefotaxime,fortum,rifampicin,polymyxin and highly resistant to penicillin,ampicillin,erythromycin,cotrimoxazol,norfloxacin and ciprofloxacin.Animal Test shows 10 strains were all highly pathogenic to mice.
