摘要: 粪检云南省昆明市太平镇捕获的31只高原姬鼠Apodemus chevrieri,在9只高原姬鼠中共发现了2种艾美球虫,自然感染率为29%,其中1种被命名为新种:齐氏艾美球虫Eimeria chevrieri sp.nov.。齐氏艾美球虫孢子化的卵囊椭圆形,大小为21·2μm×16·3μm(22·219·7μm×17·315·6μm)。卵囊壁光滑,单层,厚约1·0μm;无胚孔和卵囊余体。有12个极体,极体形状不规则,直径1·02·0μm。卵圆形的孢子囊大小为11·2μm×7·5μm(12·310·3μm×8·36·8μm),有孢子囊余体,且主要分布在2个子孢子的中间,斯氏体扁豆形,大小为1·0μm×0·3μm,亚斯氏体亚球形,大小为2·5μm×1·5μm。子孢子在孢子囊里面头尾相接,在其宽端有1个明显的反光体,直径约3μm。模式标本保存在云南大学标本馆。齐氏艾美球虫,新种Eimeria chevrieri sp·nov.(图12,4)寄生于姬鼠属,具有椭圆形的卵囊,卵囊壁具有光滑、无色、单层特点的艾美球虫有3种:E.gomurica Musaev and Veisov,1963,E.kaunensis Arnastauskiene et al.,1978和E.gandobica Musaev and Veisov,1965。E.gomurica、E.kaunensis与本种的主要区别是卵囊较小且有卵囊余体;E.gandobica与本种的主要区别是卵囊呈宽椭圆形,卵囊和孢子囊较小(19·0μm×16·8μmvs·21·2μm×16·3μm;8·0μm×5·0μmvs·11·2μm×7·5μm),孢子囊余体少,无反光体和亚斯氏体。寄生于姬鼠属,具有椭圆形的卵囊,卵囊壁具有光滑、2层特点的艾美球虫有3种:E.alorani Hurková et al.,2005、E.apodemi Pell啨rdy1974和E.zaurica Musaev and Veisov,1965。E.zaurica与本种的主要区别是具有卵囊余体;E.alorani的卵囊和孢子囊比本种大的多(26·9μm×19·3μmvs.21·2μm×16·3μm),且其孢子囊余体形成一个直径约45μm的球状结构;E.apodemi的孢子化卵囊呈宽椭圆形,经常不对称,无极体和斯氏体。该种区别其它种的关键特征是:1)孢子化卵囊椭圆形,卵囊壁光滑、单层、无色;2)有极体;3)孢子囊有亚斯氏体。模式标本,含孢子化卵囊的齐氏姬鼠粪便保存在云南大学生物系,标本编号:2006047;齐氏姬鼠标本保存于云南大学标本馆,标本编号20060081。词源:种名源自宿主种名。

摘要: The experimental beastie in this essay is only the rodent (rat, small rat, shrewmouse, cavy) and rabbit. The eimeria parasitizing in beastie are variety and frequency. Some of them are distinctly pathogeny and dangerous, so eimeria is one of debared parasites in “International Standards". All the eimerias in beastie are not touched in our country except rabbit eimeria reported systematically, so we aim to discuss it in this essay. The following are our opinions based on the information we have. 1. The 30 merias can be divided into 5 animal groups according to the eimeria's special advocation characteristic. 2. The classification nowadays is based on the conformation characteristic. It is difficult to distinguish when there are many kinds of merias, because the maturate characteristics of oocyst are different. So it is better to see if the sample is new or old when you choose the material. You can find the rule by contrasting, so that the distinguish of species is easier. 3. The conformation of oocyst is the main point of classification. We can increase the creditability of defination by the colligate judgement of observing the transformation in organize pathology cooperating the entirely process of eimeria life history, such as the asexuality procreation and sexual reproduction of eimeria in intestines cell and the form of oocyst.
