河南省畜禽几种主要致病菌的分离鉴定和耐药性检测

从临床病例对河南省畜禽主要致病菌进行了分离鉴定并进行了耐药性检测。猪主要致病菌为传染性胸膜肺炎放线杆菌、链球菌和葡萄球菌，鸡为大肠杆菌。氯霉素、庆大霉素对7株大肠杆菌中的1株高度敏感，抑菌环最大，其他普遍产生了耐药性。猪传染性胸膜肺炎放线杆菌对环丙沙星和诺氟沙星高度敏感，而对其他药物敏感性较低，对庆大霉素产生了极强的耐药性。链球菌对庆大霉素和卡那霉素有着较强的敏感性，但对青霉素产生了较强的耐药性，而葡萄球菌对青霉素和红霉素有着较高的敏感度。

Identification of Main Pathogensi of Livestock and Poultry in Western Henan and Their Drug Tolerance

The authors separated kinds of domestic animals' pathogenic bacteria from the clinical cases in western Henan and examined their drug tolerance.The results showed that chicken's main pathogenic bacteria was Escherichias coli and pig's was Actinobacillus pleuropneunoniae,steptococcus and staphylococcus.Only one of 7 strains of Escherichias coli was highly sensitive to chloromycetin and,gentamycin and the others all produced drug tolerance. pig's Actinobacillus pleuropneunoniae was highly sensitive to ciprofloxacin hydrochloride and norfloxacin and showed low sensitivation to the other drugs,especially to gentamicyn.Steptococcus was more sensitive to gentamicyn and kanamycin,but it was strongly tolerant to penicillin.Staphylococcus was more sensitive to penicillin than to other drugs.
