骆驼福斯盘尾丝虫病组织病理学观察

Histopathological observation of onchocerciasis in camels

为更有效地对骆驼盘尾丝虫病进行防治,利用流行病学调查和常规病理学观察的方法,对骆驼盘尾丝虫病进行研究。结果表明:内蒙古阿拉善左旗骆驼盘尾丝虫病平均感染率为85.4%,感染强度为1~15峰-1,虫体形成的结节分布在骆驼的颈项韧带处;共收集到209个结节,它们的形态和质地各不相同,软的结节内形成纤维组织囊腔,硬的结节内形成钙化灶;骆驼年龄段不同,结节的分布呈不同变化;病理组织学观察显示,囊腔周围有各种炎性细胞侵润,囊腔内有不同状态的雌虫虫体,骆驼盘尾丝虫病表现为骆驼的寄生虫性肉芽肿。

Epidemiological investigation and routine pathological observation were conducted to study onchocerciasis in camels for better prevention of disease caused in camels.The results showed that the infection rate of Onchocerca of camels was 85.4percent on average in Inner Mongolia and a mean intensity of 1-15nodules/host.Nodules containing the worms were observed from nuchal ligaments of camels.A total of 209 nodules were collected and their shape and texture were different.Soft nodules consisted of fibrous capsules and hard nodules formed calcification.The distribution of nodules showed different patterns with the age of the camel.Histologically,inflammatory cells around compartments and cavities contained different status of females.Camels＇ onchocerciasis caused parasitic granuloma.
