The biochemical and serological properties of 29 isolates of avian haemophili obtained from chickens in Brazil are described. Twenty-seven of the isolates had the typical biochemical properties of Haemophilus paragallinarum. The two remaining isolates had the typical properties of Pasteurella avium, formerly known as Haemophilus avium. All of the H. paragallinarum isolates were serotyped according to the Page scheme using a hemagglutination-inhibition test. Fourteen of the isolates were serovar A, one was serovar B, 11 were serovar C, and one isolate could not be serotyped. The isolates were also examined using a panel of monoclonal antibodies for Page serovars A (one monoclonal antibody available) and C (three monoclonal antibodies available). As expected, the serovar B isolate failed to react with any monoclonal antibody, whereas the 11 serovar C isolates reacted with all three serovar C monoclonal antibodies but not with the serovar A monoclonal antibody. Only eight of the 14 serovar A isolates reacted with the serovar A monoclonal antibody.
描述了从巴西鸡群中获得的29株禽嗜血杆菌的生化和血清学特性。其中27株分离株具有副鸡嗜血杆菌的典型生化特性。其余两株分离株具有禽巴氏杆菌（以前称为禽嗜血杆菌）的典型特性。所有副鸡嗜血杆菌分离株均根据Page分型方案，采用血凝抑制试验进行血清分型。其中14株为血清型A，1株为血清型B，11株为血清型C，1株分离株无法进行血清分型。还使用一组针对Page血清型A（有1种单克隆抗体）和C（有3种单克隆抗体）的单克隆抗体对分离株进行检测。正如预期的那样，血清型B分离株未与任何单克隆抗体发生反应，而11株血清型C分离株与所有3种血清型C单克隆抗体发生反应，但未与血清型A单克隆抗体发生反应。14株血清型A分离株中只有8株与血清型A单克隆抗体发生反应。
