世界绵羊(Ovis aries)球虫种类与地理分布

Coccidia Species and World Distribution of Sheep(Ovis aries)

为了解绵羊(Ovis aries)球虫的种类及在世界各地的分布情况,本文收集整理了世界上报道绵羊球虫的相关资料,按照虫种学名的字母为序,介绍了寄生于绵羊的17种艾美耳球虫(Eimeria),其中3种在中国发现与命名的球虫为卵状艾美耳球虫(Eimeria oodeus Hu and Yan,1990)、厚膜艾美耳球虫(Eimeria pachmenia Hu and Yan,1990)、固原艾美耳球虫(Eimeria guyuanensis Xiao,1992)。每种球虫包括中文名称与学名、宿主名称、寄生部位、地理分布,部分种类有同物异名,地理分布按照国家或地区的英文或拼音字母为序。在收录的56个国家中,记录球虫种类最多的国家为中国(17种),其次为巴西(13种),记录11~12种球虫的国家占32.14%,6~10种球虫的国家占35.71%,1~5种球虫的国家占28.57%。在17种绵羊球虫中,分布最广的球虫为小型艾美耳球虫(49个国家),其次为类绵羊艾美耳球虫(46个国家),分布40~45个国家的球虫种类占29.41%,20~39个国家的球虫种类占23.53%,1~19个国家的球虫种类占35.29%。本文基本能反映出绵羊球虫在世界范围的分布状况,为全面了解绵羊球虫的地理分布提供了一份较为完整的基础资料。

In order to comprehensively understand the coccidia species of sheep(Ovis aries)and their distribution in different countries,we reviewed the literatures and collected references of sheep coccidia published so far in the world.A total of 17 sheep Eimeria species were introduced with the alphabetical order of their scientific names,of which E.oodeus Hu and Yan,1990,E.pachmenia Hu and Yan,1990 and E.guyuanensis Xiao,1992 were firstly described and named in China.Each specie was listed and introduced with its Chinese name,scientific name,host name,parasitic site and geographical distribution.Some species also had their synonyms.The geographical distribution was listed with the alphabetical order according to English or Chinese name of a country or region.Among 56 countries listed,the country with the most reported coccidia species was China(17 species),followed by Brazil(13 species).32.14%,35.71% and 28.57% countries had 11-12,6-10 and 1-5 coccidia species,respectively.Among 17 sheep coccidia species discovered,the most widely distributed coccidia species was E.parva(49 countries),followed by E.ovinoidalis(46 countries).29.41%,23.53% and 35.29% species were distributed in 40-45,20-39 and 1-19 countries,respectively.This review collected the basic distribution of sheep coccidia in the world and provided necessary information for a comprehensively understanding of the species and geography of sheep coccidia.
