鸡卡氏住白细胞病病原学研究和防治技术

Etiological Study and Prevention and Treatment Technologies of Chicken Leucocytozoonosis

[目的]为鸡卡氏住白细胞虫病的防治提供依据。[方法]通过血液涂片检查、病鸡剖检、组织印片及人工接种试验对信阳地区病鸡体内和组织切片中各期病原体的形态变化观察,总结其流行规律和典型病状,并提出其防治技术。[结果]信阳市鸡卡氏住白细胞虫体在血液细胞内发育各期形态变化与国内外报道基本相同。大配子平均大小14.86μm,小配子体平均大小12μm。大配子体的数量比小配子体多。在鸡细胞内外除第3、4期配子体外,还有裂殖子。裂殖体直径为27-68μm。[结论]可在鸡饲料中添加中西药物来预防和治疗鸡卡氏住白细胞虫病。

[ Objective ] The research aimed to provide basis for the prevention and treatment of chicken leucocytozoonosis. [ Method ] The morphological changes of pathogens in each stage in diseased chicken and tissue sections were observed by using blood smear examintion, pathological observation, tissue sections and artificial infection test. The prevalence laws and typical disease symptoms were summarized. And their prevention and treatment technologies were proposed. [ Result] The morphological changes of chicken Leucocytozoon caulleryi in blood ceils in different developmental stages were basically according with the foreign and domestic reports. The average size of megagamete was 14.86 μm, and the average size of microgametocyte was 12 μm. The quantity of megagamete was more than that of microgametocyte. Besides gametophyte in stage Ⅲ and Ⅳ, there was schizozoite in chicken cells. [ Conclusion] Chinese and western medicine could be added in the chicken feed to prevent and control chicken leucocytozoonosis.
