Three experiments were carried out to examine the consequences of concurrent infections with Ascaridia galli and Escherichia coli in chickens raised for table egg production. Characteristic pathological lesions including airsacculitis, peritonitis and/or polyserositis were seen in all groups infected with E. coli. Furthermore, a trend for increased mortality rates was observed in groups infected with both organisms which, however, could not be confirmed statistically. The mean worm burden was significantly lower in combined infection groups compared to groups infected only with A. galli. It was also shown that combined infections of E. coli and A. galli had an added significant negative impact on weight gain.
进行了三项实验，以研究用于生产食用蛋的鸡同时感染鸡蛔虫和大肠杆菌的后果。在所有感染大肠杆菌的组中均观察到特征性病理损伤，包括气囊炎、腹膜炎和/或多浆膜炎。此外，在同时感染两种病原体的组中观察到死亡率增加的趋势，然而，这在统计学上无法得到证实。与仅感染鸡蛔虫的组相比，混合感染组的平均蠕虫负荷显著降低。研究还表明，大肠杆菌和鸡蛔虫的混合感染对体重增加有额外的显著负面影响。
