无角多赛特绵羊球虫感染情况和种类调查初报

应用饱和盐水漂浮法和麦克马斯特法对河南某种羊场新引进的82只1岁左右无角多赛特绵羊球虫感染情况和种类进行了调查,结果表明:10圈绵羊均感染球虫,感染率28.57%￣100%,平均为84.2%(69/82);多为2￣5种球虫混和感染;平均OPG值为839.03(200￣4200)。共检出11种艾美耳球虫,分别是:韦不理吉艾美耳球虫(Eimeria weybridgensis)、巴库艾美耳球虫(E.bakuensis)、小型艾美耳球虫(E.parva)、类绵羊艾美耳球虫(E.ovinodalis)、颗粒艾美耳球虫(E.granulosa)、槌形艾美耳球虫(E.crandllis)、阿撒他艾美耳球虫(E.ahsata)、浮氏艾美耳球虫(E.faurei)、贡氏艾美耳球虫(E.gon-zalezi)、爱缪拉艾美耳球虫(E.aemula)、苍白艾美耳球虫(E.pallida),其中前4种为优势虫种。用Miaspro图象分析处理系统软件对各种卵囊进行了测量,并进行了显微照相和形态描述。

Investigation of the Infection Situation and Spedes of Coccidia on Poll Dorset Sheep

Taking advantage of saturated salt solution and McMaster''s method, the infection status and categories of coccidia were investigated among 82 newly imported one-year-old Poll Dorset sheep in Henan. The results showed that all of the ten sheep flocks were coccidia positive and the infection rates were between 28.57% and 100% with an average of 84.2%. Most of sheep were co-infected by 2 to 5 species of coccidia.The average number of oocyst per gramme feces (OPG) was 839.03(from 200 to 4200).Eleven species of Eimeria were isolated,which respectively were E. weybridgensis, E .bakuensis, E. parva, E .ovinodalis, E. granulose, E. crandllis, E. ahsata, E. faurei, E. gonzalezi, E. aemula and E. pallida, and the first 4 isolates were predominant. The oocysts were meteraged and micriscopied by using Miaspro image analysis system software.
