摘要
调查了重庆市山羊隐孢子虫感染情况,应用饱和蔗糖溶液漂浮法对重庆市武陵山区和山峡库区6个种羊场共301份粪样进行了检测(其中每个羊场抽检率大于10%)。结果检出隐孢子虫阳性样品16份,平均感染率为5.32%,场感染率为50%,均在山峡库区,种羊场阳性率最高为21.1%;不同年龄阶段感染情况为:以2～3月龄羔羊、产后1月和怀孕2月左右母羊的感染率较高,分别为9.68%、10.5%和6.67%。所检出的隐孢子虫卵囊经形态学观察,初步鉴定为微小隐孢子虫(C.Parvum)。
In order to survey the goats cryptosporidium infection,a total of 301 fecal samples in goats on 6 goat breeding farms in Wulin mountainous areas and gorges reservoir areas of Chongqing were collected and analyzed by flotation technique using saturated sucrose. Ten percent of goats were examined. The number of positive fecal samples in goats were 16. The infection rates in the goats from 6 farms were 5.32~. The prevalence rate of farms in goats was 50%, all in gorges reservoir area. The highest infectionrate of farm was 21.1%. 2 to 3 months old goats, 1 month old kids after delivery and the goats with 2 months pregnancy had high infection rates, which were 9.68%, 10.5% and 6.67%, respectively.
