内蒙古双峰驼斯氏副柔线虫病的流行病学调查

Epidemiological investigation of Camelus bactrianus parabronemosis in Inner Mongolia

在2009-2011年,利用剖检法和病理组织切片技术,对内蒙古5个地区的152峰双峰驼进行了斯氏副柔线虫病的流行病学调查和病理学研究。结果显示,在被调查的152峰双峰驼中有117峰感染了斯氏副柔线虫,感染率为77.0%,最高感染强度为1 315条,骆驼真胃内斯氏副柔线虫的雌、雄虫比例在3.9∶1～1.2∶1之间;患驼的肉眼病变率为42.7%,大量感染斯氏副柔线虫的骆驼真胃黏膜有溃疡、脱落、淤血、出血,组织腺泡上皮细胞浓缩、变性,淋巴细胞异常增生。调查证实,斯氏副柔线虫病对内蒙古养驼业危害严重,应加强防治。

In order to learn the epidemic situation and pathological changes on parabronemosis,a total of 152 camels from 5 different areas in Inner Mongolia from 2009 to 2011 were studied by the method of dissection and histopathologic slide technique.In result,117 camels were infected by Parabronema skrjabini,and the infection rate was 77.0%.The maximum infection intensity was 1 315 nemotodes per camel.The proportion of female to male P.skrjabini was from 1.2∶1 to 3.9∶1.The 42.7% of the infected camels developed pathological changes in abomasum when examined with naked eye.Large number of P.skrjabini infection can lead to ulcus,desquamation,gore,hemorrhage,concentration and of epithelial cells,and lymphocytic infiltration in abomasum mucosa.The results confirmed that parabronemosis had a serious damage to camel in Inner Mongolia,and it should be controlled specially.
