The present paper reports the prevalence of coccidiosis in industrial broiler chickens in Faisalabad, Punjab, Pakistan to determine the occurrence of different species of Eimeria in the area and to assess their correlation with the environmental conditions including temperature, humidity and rainfall. The study was conducted from January 2009 to December 2010. Examination of chicken guts revealed 43.89% (n = 3,283/7,480) prevalence of coccidiosis. The highest prevalence (27.04%) was recorded of Eimeria tenella followed by Eimeria maxima (22.42%), Eimeria acervulina (19.89%) and Eimeria necatrix (4.02%). The prevalence of disease was significantly higher (P < 0.05) in autumn (60.02 ± 4.38) followed by summer (47.42 ± 2.92), spring (36.92 ± 2.27) and winter (29.89 ± 3.43). Likewise, prevalence of different species of Eimeria also varied (P < 0.05) in different seasons of the year except that of E. necatrix. A strong correlation (P < 0.05) of environmental conditions with the overall and species-wise prevalence of coccidiosis was recorded except E. necatrix.
本文报告了巴基斯坦旁遮普省费萨拉巴德工业肉鸡球虫病的流行情况，以确定该地区不同种类艾美耳球虫的发生情况，并评估它们与包括温度、湿度和降雨在内的环境条件的相关性。该研究于2009年1月至2010年12月进行。对鸡肠道的检查显示球虫病的患病率为43.89%（n = 3,283/7,480）。柔嫩艾美耳球虫的患病率最高（27.04%），其次是巨型艾美耳球虫（22.42%）、堆型艾美耳球虫（19.89%）和毒害艾美耳球虫（4.02%）。秋季疾病患病率显著更高（P < 0.05）（60.02 ± 4.38），其次是夏季（47.42 ± 2.92）、春季（36.92 ± 2.27）和冬季（29.89 ± 3.43）。同样，除了毒害艾美耳球虫外，不同种类艾美耳球虫的患病率在一年的不同季节也有所不同（P < 0.05）。除了毒害艾美耳球虫外，环境条件与球虫病的总体患病率和按种类划分的患病率之间存在很强的相关性（P < 0.05）。
