摘要: 从贵州省临床疑似鸭传染性浆膜炎发病鸭鹅中分离病原菌,经细菌分离培养、细菌形态、培养特征及生化试验,初步鉴定出疑似鸭疫里默氏杆菌(Riemerella anatipestifer,RA)20株,经PCR和动物接种试验,其中9株鉴定为RA。对不同地区分离到的这9株菌进行血清型鉴定和15种常规抗菌药物的药敏试验。结果发现,9株RA中4株为血清2型,其余5株暂未鉴定出血清型;9株分离株中,对吡哌酸、链霉素、卡那霉素和红霉素等耐药的菌株比例为80%以上,对先锋霉素高度敏感的菌株比例较高。结果表明,本次分离的RA菌株生化试验鉴定结果与其他地区存在一定差异,不同地区分离到的RA对不同抗菌药的敏感程度存在较大差异性。本研究结果为该地区鸭传染性浆膜炎的药物防制提供了很好的理论依据。

Abstract: Pathogens were isolated from the ducks and gooses with typical serositis in farms of Guizhou areas. According to bacterial isolation and culture, the bacteria morphology, gram's staining results, bacteria growth requirements, colonial morphology and biochemical properties,twenty strains of suspected Riemerella anatipestifer (RA) were identificated preliminarily, and nine strains were identified as RA by PCR tests and animal inoculation tests. The isolated strains were serotyped, and antibiotic sensitivity analysis of isolated strains were detected with fifteen kinds of antibiotics. The results showed that these isolates had 4 strains of serotype 2, and 5 strains were not serotyped. These isolates were not so sensitive to some frequently used medicines such as pipemidic, streptomycin, kanamycin and erythromycin ratio of up to 80%, and only were sensitive to cephalothin.The results showed that there were some differences in identification results of biochemical test between the isolated RA strains and that of other regions, and different results were gained among strains isolated from different farms. All results obtained from this study provided a foundation for the medicinal therapy of duck infectious serositis in Guizhou province.
