摘要
对分离于发病死亡鸡的12株沙门菌(Salmonella),进行了形态特征、理化特性、血清型、致病作用、药物敏感性等主要表观性状及系统发育的研究。其中包括O4(B)群无动力沙门菌(Salmonellagroup B O form)2株(EU073022),血清型1,4,5,12:-:-;鸡沙门菌(S.gallinarum)2株(EU073018),血清型1,9,12:-:-;病牛沙门菌(S.bovismorbificans)5株(EU073019),血清型6,8:r:1,5;肠炎沙门菌(S.enteritidis)3株(EU073020),血清型1,9,12:g,m:-。人工感染试验表明,均具有较强的致病作用;药物敏感性试验结果显示,在不同菌株间的敏感、耐药等差异不明显。
12 trains isolated from diseased chicken were researched and analyzed for their morphological characteristics,physiological and biochemical characteristics,serotype,pathogenic effect,drug susceptibility and phylogenesis.The information on 12 trains was described as follows：2 trains salmonella group B O form（EU073022）,serotype is 1,4,5,12：-：-;2 trains s.gallinarum（EU073018）,serotype is 1,9,12：-：-;5 trains s.bovismorbificans（EU073019）,serotype is 6,8：r：1,5 and 3 trains S.enteritidis（EU073020）,serotype is 1,9,12：g,m：-.The results showed that pathogenic bacteria had strong pathogenicity to healthy chicken by experimental infection,meanwhile there was no discrepancy of sensitivity and drug resistance among trains by antimicrobial agents.
