摘  要:
采用组织切片技术,观察了用不同剂量柔嫩艾美球虫(E.tenella)YL株孢子化卵囊感染的同一日龄雏鸡和用同一剂量柔嫩艾美球虫YL株孢子化卵囊感染的不同日龄雏鸡的组织病理学变化,并对不同组别的卵囊和配子体数量进行了统计。结果显示,不同剂量组中,1×105卵囊感染组配子体和卵囊的产量明显高于1×103和1×104卵囊感染组,其组织病理学变化也明显,但在感染后第9~11 d,1×103和1×104感染组卵囊数较1×105组多;同一剂量(每只鸡1×103卵囊)感染时11日龄雏鸡的组织病理学变化明显,说明鸡的日龄越大卵囊产量越高。

摘  要:
The histopathological changes of chickens infected with different doses of sporulated oocysts of Eimeria tenella YL strain were observed by tissue section technology.Gametocytes and oocysts were counted.The results showed that gametocytes and oocysts in GroupⅢ infected with 1×105 oocysts were significantly higher than those in GroupⅠ infected with 1×103 oocysts and GroupⅡ infected with 1×104 oocysts.The histopathological changes of chickens in GroupⅡ and Ⅲ were also obvious.The oocyst outputs in GroupⅠand Ⅱ were higher than that in Group Ⅲ during days 9 to 11 post-infection.The histopathological changes of the 11-day-old chickens infected with 1×103 oocysts were obvious,indicating that the oocyst output increased along with the increase of age.
