摘要
对重庆地区的永川、壁山、江津、荣昌等地家兔的球虫感染情况进行调查,发现兔的艾美尔球虫感染率为100％,以断奶后至2月龄的幼兔最易感染,死亡率高。本次共检出兔的13种艾美尔球虫,即:斯氏艾美尔球虫(Eimeria stiedae),大型艾美尔球虫(E.magna),中型艾美尔球虫(E.media),梨形艾美尔球虫(E.piriformis),黄艾美尔球虫(E.flavescens),盲肠艾美尔球虫(E.coecicda),肠艾美尔球虫(E.intesstinalis),兔艾美尔球虫(E.leporis),穿孔艾美尔球虫(E.perfoans),小型艾美尔球虫(E.exigua),新兔艾美尔球虫(E.neoleporis),无残艾美尔球虫(E.irrestidua)和松林艾美尔球虫(E.matsubayashii),其主要致病虫种为斯氏艾美尔球虫、大型艾美尔球虫和梨形艾美尔球虫。
The investigation was carried out by examining feces of rabbits from Chongqing. The infection rates of coccidian in rabbits were 100% and the infection rates and death rate in young rabbits from weaning to 2 - months age were higher than those in other age. Thirteen species of Eimeria coccidia wrer found and identified. They are E. siedae, E. magna, E. media, E. exigua, E. irrestidua , E. coecicda , E. intestinais , E. pinformis , E. leporis, E. perfoans , E. neoleporis , E. matsubayashii, E. flavescens , which E. perfoans, E. magna and E. pinformis had stronger pathogenicity.
