【摘要】 为了解河南省绵羊肠道寄生虫感染情况,应用寄生虫常规检测方法对5个规模化养羊场共1265份粪样进行了寄生虫感染情况调查。结果显示,共检出虫卵和卵囊5类,其中原虫2类(球虫、隐孢子虫)、线虫2类(类圆线虫、鞭虫)、绦虫1类。本次调查中共发现1178份粪便样品为寄生虫阳性,寄生虫总感染率为93.12%(1178/1265),5个绵羊场的隐孢子虫平均感染率为3.10%,球虫平均感染率为88.94%,鞭虫平均感染率为10.83%,类圆线虫平均感染率为59.11%,绦虫平均感染率为43.96%。本次调查发现绵羊寄生虫混合感染现象比较严重,其中球虫、绦虫和类圆线虫混合感染的比例达到60.10%;绵羊寄生虫感染率呈现随着年龄的增长而减少的趋势。更多还原

【Abstract】 In order to understanding the prevalence of intestinal parasites in sheep in Hennan province,1265 sheep faecal samples from 5 farms were detected by the convention methods.The results showed that 5 groups parasites were detected in stool specimens,2 groups were protozoon(coccidian,cryptosporidium),2 groups were nematode(trichuris ovis,strongyloides stercoralis),1 group was cestode.As a result,the average infection rate was 93.12%(1178/1265),thereinto,the infection rate of cryptosporidium sp was 3.10%,eimeria sp was 88.94%,trichuris sp was 10.83%,strongyloides sp was 59.11%,cestode was 43.96%,respectively.The results showed that sheep parasites mixed infections are more serious,in addition,the mixed infection of eimeria sp,tapeworm and strongyloides stercoralis took up 60.10% of the total infections rate.The results showed that sheep infection rate was reduction with the age increased.更多还原
