摘要
从闽北地区几个大型养鸡场的发病鸡群的病、死鸡的内脏和死胚中分离到 118株大肠杆菌 ,对其进行了生化试验、致病性试验和血清型鉴定。其中有 76株具有致病性 ,占分离菌的64.4 % ;除了 14株未能定型外 ,共鉴定出 62株分离菌的 O血清型 ,这些定型菌株共有 11个血清型 ,以 O78、 O2 、和 O1为优势血清型 ,分别占鉴定菌株的 38.7%、 19.4 %和 11.3%
One hundred and eighteen strains of Escherichia coli (E coli) were isolated from the dead chicken embryoes and the viscera of ill or dead chicken from some chicken farms in northern Fujian.The test of biochemistry, pathogenicity and serotype identification were also conducted.76 strains had pathogenicity, accounted for 64 4 percent of all the isolated E coli Exception of 14 strains which couldn't be determined their serotype, 62 E coli were indentified as serum O, among which O 78 (38 7 percent)、O 2 (19 4 percent) and O 1 (11 3 percent) were the dominant types.
