口蹄疫的有效控制关键在于早期检测 ,然而有很多疾病症状与口蹄疫相似 ,仅靠临床症状难以确诊 ,因此必须进行实验室诊断。实验室诊断包括病毒学诊断和血清学诊断。病毒学诊断方法有病毒分离、补体结合试验、酶联免疫吸附试验 ( EL ISA)、RT-PCR以及乳胶凝集试验 ( L AT)。 RT-PCR有待进一步完善 ,而用于野外检测的现场诊断方法已取得可喜进展。血清学诊断包括中和试验和 EL ISA,中和试验已经被 EL ISA方法取代 ,并且通过检测非结构蛋白的抗体可以区分感染动物和免疫动物。更加快速、敏感、可靠以及用于检测潜伏感染的诊断技术将是今后研究的热点。
【英文摘要】
Earlier diagnosis is the key to control FMD,however there are lots of diseases with the same clinical signs and the presence of clinical signs alone is inconclusive, laboratory diagnosis shoud always be carried out. The laboratory diagnosis includes virological diagnosis and serological diagnosis. The presence of FMD viruses can be demonstrated by cell culture isolation, complement fixation test, ELISA,the more recent reverse transcription polymerase chain reaction (RT-PCR) and latex agglutination test (LAT...
