山羊球虫病流行病学调查及应用电脑技术鉴别虫种

采用饱和盐水漂浮法、麦克马斯特氏法、卵囊培养等方法及应用电脑和配置有彩色数码摄像机的双目光学显微镜设备,在毕节市8个县（区）、24个乡（镇）、26个养殖户（场）开展了山羊球虫病流行病学调查,对339只山羊粪样进行了定性、定量检查和胞子化培养,并应用电脑技术对山羊球虫的卵囊种类进行了鉴别.结果显示,球虫卵囊的感染率96.75％;OPG值在100～472 700枚之间,平均OPG值为8 570枚,鉴别出艾美耳属球虫8种,并对其卵囊的形态学特征进行了详细地描述.调查结果基本反映了当地山羊球虫的感染状况,表明了在电脑上直接观察、记录和测量球虫卵囊的方法比在显微镜下方便,测量也较为准确.

Application of Computer Technology in Identification of Goat Coccidiosis Species

A total of 339 goat fecal specimens were collected in Bijie city of Guizhou Province and examined for the presence of coccidian oocysts by using floating method, McMaster＇s method and oocyst cultures. A color digital camera with binocular optical microscope was linked to a computer so that observation, recording and measurement of coccidian oocysts could be completed on the computer screen. The positive rate of coccidian oocysts was 96.72% and OPG ranged from 100 to 472 700 （average 8 570）. Eimeria tenella was identified in 8 fecal specimens and the morphology of their oocysts was described. These results demonstrated that the direct observation, recording and measuring oocysts on the computer were more convenient than under the microscope not only, but also more accurate.
