摘要: 设计了一种灵敏的EMISA竟争抑制法,用以检测实验动物多杀性巴氏杆菌。在该系统中,从多杀性巴氏杆菌P-1059、X-73和A-898中抽提可溶性物质作为包板抗原。用3株全菌体免疫兔,提纯兔抗多杀性巴氏杆菌IgG,用辣根过氧化物酶标记兔抗多杀性巴氏杆菌IgG,将酶结合物与待检动物血清做ELISA竞争抑制试验。同时用常规ELISA间接法做验证实验。结果表明此法准确可靠,可用于各种实验动物的多杀性巴氏杆菌的检测。对小鼠、仓鼠、兔的检测表明,兔的P-1059阳性率达30%,小鼠、仓鼠未见阳性。

Abstract: A rapid sensitive ELISA inhibitory test was designed to detect Pasteurella multocida infection in laboratory animals. In the reactive system, the soluble material extracted from P. multocida(P.m)strain P-1059 X-73 or A-898 was used as coating antigen, rabbits were immunized with these three strains of whole bacteri resapecti-vely. The purified rabbits IgG of anti-P.m was labeled with HRP by sodium periodate method. The HRP labeled rabbit anti-P. m IgG was mixed with animal serum samples to operate ELISA inhibitory test. The conventional indirect ELISA was performed to confirm the results. It was found that infective rate of P.m strain P-1059 in rabbits was as high as 30%; while in mice and hamsters, no positive samples were detected. The results indicated that this is an easy, rapid and reliable method for the detection of P. m infection in laboratory animals.
