Of the 3 respiratory tract disease syndromes that occur in birds associated with Escherichia coli infection, acute colisepticemia, characterized by hyperemic and swollen viscera, tended to occur in young birds. Subacute fibrinopurulent serositis involving air sacs and pericardium was more common in older birds. Chronic granulomatous pneumonitis was not seen as flock epornitics but as chronic disease in birds dying in small numbers some time after one of the previously mentioned forms of the disease. Serotypes of 100 E coli isolates from turkey colibacillosis revealed most to be O1, O2, O36, or O78. Virulence of the isolates, as conducted by IV inoculation of 6-week-old turkeys, showed O78 strains to be highly virulent and O36 strains to vary in virulence.
在与大肠杆菌感染相关的鸟类发生的三种呼吸道疾病综合征中，以内脏充血和肿胀为特征的急性败血病往往发生在幼鸟身上。涉及气囊和心包的亚急性纤维蛋白脓性浆膜炎在成年鸟中更为常见。慢性肉芽肿性肺炎并非以禽群疫病形式出现，而是在上述疾病的某种形式发生一段时间后，以少量鸟类死亡的慢性病形式出现。从火鸡大肠杆菌病中分离出的100株大肠杆菌血清型显示，大多数为O1、O2、O36或O78。通过对6周龄火鸡进行静脉接种来检测分离株的毒力，结果显示O78菌株具有高毒力，O36菌株的毒力有所不同。
