摘要
1999年 3月~ 2 0 0 0年 12月 ,从福建省 10 3个肉鸭场采集具有典型三炎 (心包炎、肝周炎和气囊炎 )的病 (死 )鸭肝脏116份 ,共分离到细菌 10 7株 ,细菌的分离率为 92 .2 % ,其中鸭疫里默氏菌 84株 ,占 78.5 % ;大肠杆菌 2 3株 ,占 2 1.5 %。在分离鉴定的 84株RA中 ,血清 1型占 2 5 .0 % ,2型占 6 0 .7% ,13型占 1.2 % ,未定型占 13.1%。可见我国目前流行的鸭疫里默氏菌 ,其血清型已发生了明显变化 ,2型和 1型已成为主要流行的血清型 ,其中 2型为优势血清型 。
liver specimens were collected from the diseased or dead ducks with fibrinous pericarditis,perihepatitis and airsacculitis of 103 duck farms in Fujian province,from March of 1999 to December of 2000.107 strains of bacteria were isolated from these livers,in which Riemerella anatipestifer (RA) constituted 78.5% (84/107),while E.coli covered 21.5% (23/107).In all 84 strains of RA,serotype 1 took up 25.0%,serotype 2 60.7%,serotype 13 1.2% and unknown serotype 13.1% by using slide agglutination test.The results showed serotype 2 and 1 were main serotype of RA in Fujian province,in which serotype 2 was preponderant.It was first reported in Fujian province.
