协同凝集试验(Co—agglutination,CoA)在细菌、病毒等病原微生物的鉴定和某些疾病的早期诊断方面应用较普遍,在兽医方面报道较少。炭疽是一种人畜共患的急性传染病,在动物炭疽的诊断和皮毛等标本的检疫中,目前主要采用 Ascoli 氏试验(环状沉淀试验)作为主要检疫方法。Ascoli 氏试验在诊断炭疽上特异性、敏感性均存在一定问题,因此,在炭疽的快诊及皮毛等标本检疫中迫切需要一种特异、敏感、简便的试验方 Co-agglutination (CoA) is widely used in the identification of pathogenic microorganisms such as bacteria and viruses and in the early diagnosis of some diseases, and less in veterinary medicine. Anthrax is a zoonotic infectious disease. In the quarantine of animal anthrax and fur samples, Ascoli’s test (cyclical sedimentation test) is the main method of quarantine. Ascoli’s test has certain problems in the diagnosis of anthrax. Therefore, there is an urgent need for a specific, sensitive and simple test for the rapid diagnosis of anthrax and the quarantine of samples such as fur
