摘要
为了探明天水市规模场和散养户羊弓形虫病的感染率、发病率、死亡率等情况,采用羊颈静脉无菌采血制备血清,通过实验室检测发现有感染阳性病例。实验结果表明,天水市不论规模养殖场还是散养户,其羊弓形虫病多有零星发生,且发生不具有明显的季节性和时效性;规模场的羊弓形虫病感染较低,本地散养户羊感染程度相对较高,且外来羊的感染率高于本地羊,并呈隐性感染态势。本研究为天水市防治羊弓形虫病综合防治提供依据。
In order to understand the infectious rate, morbidity and mortality of ovine toxoplasmosis in large-scale farms and small raising-households in Tianshui, in this study, aseptic blood sampling of the jugular vein was used to prepare the serum, and then positive samples were found by laboratory tests. The results revealed that toxoplasmosis occurred sporadically in large-scale farms and small raising-households, without obvious seasonal patterns and timeliness. Comparatively, the infectious rate of toxoplasmosis was higher in local small raising-households than that in large-scale farms, and also higher in imported sheep than that in local sheep. Moreover, the infection tends to be occult. The study will provide a clue for prevention and control of ovine toxoplasmosis in Tianshui.
