摘要
从四川某鸭场送检的病料中分离到1株疑似鸭疫里默氏杆菌(Riemeralla anatipestifer,RA)。经细菌形态学、培养特性、生化试验、PCR扩增与动物回归试验鉴定后,证实为鸭疫里默氏杆菌。该菌尿素酶试验阳性,不能发酵多种糖类,不能液化明胶,不产生H2S,不还原硝酸盐,吲哚试验、MR试验、VP试验均为阴性;菌株对左氟沙星、氧哌嗪青霉素、庆大霉素等极为敏感,而对青霉素、头孢拉定、链霉素等耐药。
A suspected Riemeralla anatipestifer（RA） strain was isolated from ducks with disease of typical fibrinous percarditis,perihepatitis and airsacculitis in Sichuan province. By a series of systematic indentification,it was demonstrated to be Rierneralla anatipestifer. It produced urease,could not ferment carbohydrates, and could not produced H2 S, nitrate, Indol, MR and VP test were negative. The isolated strain was highly susceptible to levofloxacin, gentanicin, piperacicin etc, and was not susceptible to streptomycin, penicilin, cefradine and so on.
