65株不同圈养野生动物源性肠杆科菌的药敏分析

采用K-B法药敏试验,分析圈养野生动物肠杆科菌对青霉素类、头孢类、氨基糖甙类、喹诺酮类、磺胺类的10种临床常用抗生素的药敏情况。结果显示：最敏感的是头孢稀类的三代头孢,头孢哌酮和头孢噻肟,其敏感率均为83.1%;较敏感的为喹诺酮类和氨基糖甙类药物,敏感率大于或等于60%;敏感性较差的是一代头孢中的头孢拉定、磺胺类药中的复方新诺明、青霉素类的氨苄青霉素,其敏感性分别为58.5%、43.1%和21.5%,被研究结果为兽医临床用药提供了依据。

Application of the Antimicrobial Susceptibility Test for Enterobacteriaceae in 65 Species of Captive Wild Animals

Using the method of K-B antimicrobial susceptibility test（AST）,we analyzed the drug susceptibility of intestinal rod bacteria to 10 kinds of clinical antibiotics including penicillins,cephalosporins,dilute aminoglycoside,quinolones,and sulfonamides.Intestinal rod bacteria were sampled from wild animals held at Hangzhou Zoo.The most effective drugs were the third generation cephalosporin,cefoperazone,and cefotaxime,which eliminated 83.1%of bacteria.Less effective antibiotics included quinolone and aminoglycoside drugs,which eliminated 60%or more of bacteria.Least effective was cefradine,a first generation cephalosporin.Effectiveness of cephradine was 58.5%,while that of ampicillin penicillin was 43.1%,and that of sulfamethoxazole of quinolone sulfa was 21.5%.This research provides a basis for clinical medication of captive wildlife.
