Passive immunity against gastrointestinal infections has recently been successfully applied as prophylaxis and therapy in patients in a variety of virally and bacterially induced infections. Campylobacter jejuni is frequently associated with acute diarrhoea in humans, and several species of animals have been shown to transmit the disease, although birds have been implicated as the main source of infection. We used bovine and chicken immunoglobulin preparations from the milk and eggs, respectively, of immunized animals for prophylactic and therapeutic treatment of chickens infected with C. jejuni. A marked prophylactic effect (a >99% decrease in the number of bacteria) was noted using either antibody preparation, whereas the therapeutic efficacy, i.e. when antibodies were given after the infection was established, was distinctly lower (80-95%) as judged by faecal bacterial counts. These observations may serve as a starting point for experiments aimed at elimination of the infection in an industrial or farm setting. It may also encourage future attempts to treat, prophylactically or therapeutically, patients with Campylobacter-induced diarrhoea.

:最近,针对胃肠道感染的被动免疫已成功应用于各种病毒和细菌引起的感染的预防和治疗中。空肠弯曲菌常与人类急性腹泻有关,尽管鸟类被认为是主要的感染源,但已显示出几种动物可传播这种疾病。我们分别使用免疫动物的牛奶和鸡蛋中的牛和鸡免疫球蛋白制剂对空肠弯曲杆菌感染的鸡进行预防和治疗。两种抗体制剂均具有显着的预防作用(细菌数量减少> 99%),而判断的治疗效果(即在感染确定后给予抗体)则明显较低(80-95%)通过粪便细菌计数。这些观察结果可作为旨在消除工业或农场感染的实验的起点。它还可能鼓励将来尝试预防性或治疗性弯曲杆菌引起的腹泻患者。
