重庆市部分种羊场山羊肠道寄生虫感染情况调查

A Survey of Prevalence of Intestinal Parasites in Goats in Part of the Breeding Farms of Chongqing

调查了重庆市山羊肠道寄生虫感染情况,采用卢戈氏碘液染色法、离心沉淀法、饱和蔗糖溶液漂浮法对重庆市武陵山区和三峡库区6个种羊场共301份粪样进行了检测.结果检出肠道寄生虫7种(类),总感染率为98.67%,以球虫、阿米巴、圆线虫为主要感染虫种,感染率分别为94.68%,63.12%,41.86%,其中球虫每克粪便中所含卵囊数(OPG)值最高为28 200,圆线虫每克粪便中所含虫卵数(EPG)值最高为7 800;贾第虫、鞭虫、莫尼茨绦虫、矛形双腔吸虫感染率分别为23.59%,3.32%,2.66%,1.66%.总混合感染率为86.71%,主要为2和3种寄生虫混合感染.球虫、圆线虫、阿米巴的场感染率为100%;贾第虫场感染率为83.33%;绦虫的场感染率为66.67%;鞭虫的场感染率为50%;吸虫的场感染率为33.33%.结果表明重庆山羊肠道寄生虫感染较普遍,应加强综合防治措施.

In order to survey intestinal parasitic infection in goats in Chongqing, a total of 301 fecal samples in goats from 6 goat breeding farms in the Wulin Mountain Area and the Three Gorges Reservoir Area of Chongqing were collected and examined for the presence of oocysts or eggs using the Lugol＇s iodine-solu- tion staining method, the centrifugation method and the Sheather＇s sugar flotation technique. Seven intesti- nal parasite species were discovered and the overall infection rate was 98.67 %. Coccidian, Entamoeba and Strongylus spp. were found to be the major infective parasites, their infection rate being 94.68%, 63.12% and 41.86%, respectively. The oocysts per gram faeces （OPG） and the eggs per gram faeces （EPG） of Coccidian and Strongylus spp. were as high as 28200 and 7 800, respectively. The infection rates of Giardia , Trichuris , Moniezia and 1.66 %, respectively. Of all the samples 86. Dicrocoelium dendriticum were 23.59%, 3.32% ,0, 2.66% and 71% were mixed infection, mainly mixed infections of 2 and 3 parasites. The farm infection rates of Coccidian, Strongylus spp. of Giardia spectively. , Moniezia, Trichuris and D. dendriticum were 83. and 33%. Entaraoeba were 100 %, and those , 66.67%, 50% and 33.33%, re In conclusion, intestinal parasitic infection in goats was shown to be quite prevalent in Chongqing and, therefore, comprehensive measures for their control and prevention should be taken and strengthened.
