摘要: 本研究对广东部分地区不同品种家禽空肠弯曲杆菌的流行状况进行了调查。通过菌落和菌体形态、生化特征、培养特性等生物学特性和多重PCR方法对所分离菌株进行鉴定,结果表明广东地区鸡、鸭和鹅空肠弯曲杆菌的带菌率分别为7.93%、2.46%和4.16%。从分离株中选取10株进行了致病性试验,结果表明禽源空肠弯曲杆菌对雏鸡的主要病理变化是腹泻便血,肝脏出现白色坏死灶,盲肠充血、膨大充满气泡和红色内容物。

关键词: 空肠弯曲杆菌; 分离鉴定; 致病性

Abstract: In this study, we conducted a survey on the prevalence of Campylobacter jejuni of different varieties of poultry in parts of Guangdong province and identified isolates according to the biological characteristics, such as colony and cell morphology, and cultivating characteristics, and multiplex PCR method. The results showed that Campylobacter jejuni infection rates of chickens, ducks and geese in Guangdong region were respectively 7.93%, 2.46% and 4.16%. The result of clicksFpathogenicity test of 10 selected from the isolates showed that the main pathological changes of the avian Campylobacter jejuni diarrhea, blood in the stool, liver white necrosis of the cecum congestion, swelling filled with bubbles and red contents.

Key words: Campylobacter jejuni; identification and isolation; pathogenicity
