An indirect hemagglutination test (IHA) and a coagglutination test (CA) were evaluated using saline, boiled, and autoclaved extracts for serotyping Haemophilus parasuis. CA showed several cross-reactions, whereas IHA gave rise to specific reactions, with minor exceptions. IHA was further compared with the immunodiffusion test (the "gold standard") for the serotyping of 67 field isolates. As a conclusion, IHA is recommended as a useful method for sensitive and specific serotyping of H. parasuis.
使用生理盐水提取物、煮沸提取物和高压灭菌提取物对副猪嗜血杆菌进行血清分型,评估了间接血凝试验(IHA)和协同凝集试验(CA)。CA显示出几种交叉反应,而IHA除了少数例外情况外,产生了特异性反应。将IHA与免疫扩散试验(“金标准”)进一步比较,用于67株现场分离株的血清分型。结论是,IHA被推荐为副猪嗜血杆菌敏感和特异性血清分型的一种有用方法。
