Thirty-two Riemerella anatipestifer isolates from ducks were serotyped by agar gel precepitin test using chicken antisera against serotypes 1 to 19 R. anatipestifer reference strains. The heat stable saline extracts from 29 field isolates reacted with the antisera of serotypes 1, 6, 7, 10, 11, 14, or 19. The isolates belonging to serotype 1 were the most prevalent (56.3%). Antigens from the remaining three isolates did not react with any of the available antisera. Additional investigations showed that they represent two new serotypes, serotypes 20 and 21.
使用针对1至19型鸭疫里默氏杆菌参考菌株的鸡抗血清，通过琼脂凝胶沉淀试验对32株来自鸭的鸭疫里默氏杆菌分离株进行血清分型。29株田间分离株的热稳定盐水提取物与1、6、7、10、11、14或19型抗血清发生反应。属于1型的分离株最为常见（56.3%）。其余三株分离株的抗原与任何可用抗血清均无反应。进一步研究表明，它们代表两种新血清型，即20型和21型。
