Oral inoculations of sporulated oocysts of Eimeria acervulina, E. necatrix, E. brunetti, E. tenella, or none were given to five groups of 4-wk-old chicks. Fecal samples were taken at 1, 3, 5, 6, 7, 8, 11, 14, and 21 days postinoculation and total fecal aerobe, total fecal anaerobe, fecal lactobacilli, and fecal coliform concentrations were enumerated. Fecal aerobe concentrations increased 10-fold during the period from 3 to 8 days postinoculation. Fecal anaerobe concentrations had small increases from 3 to 6 days. Fecal lactobacilli concentrations increased with E. necatrix and E. brunetti infections but decreased with E. tenella infections. Fecal coliform concentrations increased most with the duodenal infections and increased less with posterior tract infections.
给五组4周龄雏鸡经口接种堆型艾美耳球虫、毒害艾美耳球虫、布氏艾美耳球虫、柔嫩艾美耳球虫的孢子化卵囊，或不接种。在接种后第1、3、5、6、7、8、11、14和21天采集粪便样本，对粪便中的需氧菌总数、厌氧菌总数、乳酸杆菌和大肠菌群浓度进行计数。接种后3至8天期间，粪便需氧菌浓度增加了10倍。粪便厌氧菌浓度在3至6天有小幅增加。感染毒害艾美耳球虫和布氏艾美耳球虫时，粪便乳酸杆菌浓度增加，而感染柔嫩艾美耳球虫时则降低。十二指肠感染时粪便大肠菌群浓度增加最多，后段肠道感染时增加较少。
