Effect of Eimeria tenella infection on Salmonella typhimurium infection of chickens was tested using feed experimentally contaminated with S. typhimurium. Four experiments were conducted. In Experiments 1 and 2, chickens received feed contaminated with 10(3) or 10(2) cfu of S. typhimurium per g for 5 days after E. tenella infection. In Experiments 3 and 4, chickens were fed feed contaminated with 10(2) or 10 cfu of S. typhimurium per g for 3 days before E. tenella infection. In all experiments, chickens were necropsied 3 to 14 days after E. tenella infection. The number of S. typhimurium in the cecal contents was counted and the presence of the organism in the liver and bile was examined. In Experiments 1 and 2, there was no significant difference in S. typhimurium infection between the group infected with S. typhimurium alone and the group infected with both E. tenella and S. typhimurium. In Experiments 3 and 4, S. typhimurium counts in the cecal contents of chickens in the concurrently infected group were significantly greater than those of chickens in the S. typhimurium alone-infected group.
利用经鼠伤寒沙门氏菌实验污染的饲料，测试了柔嫩艾美耳球虫感染对鸡鼠伤寒沙门氏菌感染的影响。进行了四项实验。在实验1和2中，柔嫩艾美耳球虫感染后，鸡连续5天食用每克含10³或10²cfu鼠伤寒沙门氏菌的污染饲料。在实验3和4中，柔嫩艾美耳球虫感染前，鸡连续3天食用每克含10²或10 cfu鼠伤寒沙门氏菌的污染饲料。在所有实验中，柔嫩艾美耳球虫感染后3至14天对鸡进行剖检。计算盲肠内容物中鼠伤寒沙门氏菌的数量，并检查肝脏和胆汁中该菌的存在情况。在实验1和2中，单独感染鼠伤寒沙门氏菌的组与同时感染柔嫩艾美耳球虫和鼠伤寒沙门氏菌的组之间，鼠伤寒沙门氏菌感染无显著差异。在实验3和4中，同时感染组鸡盲肠内容物中鼠伤寒沙门氏菌的计数显著高于单独感染鼠伤寒沙门氏菌组的鸡。
