天山马鹿南山种群肠道寄生虫的流行病学调查

为了解野生天山马鹿胃肠道寄生虫感染情况,2011 年10 月至2012 年6 月和2012 年9 月,利用漂浮法和沉淀法,对分布于新疆乌鲁木齐南山山区天山马鹿的306 份马鹿粪便进行了调查。结果表明,天山马鹿寄生虫感染情况较为严重,主要有鞭虫卵、蛔虫卵、球虫卵、线虫卵和幼虫,总感染率高达85. 6% 。其中鞭虫卵、蛔虫卵、球虫卵及其他(未能鉴定分类的线虫卵和幼虫)的平均感染率分别为78.1% 、56. 9% 、0.7% 和25. 8% ,感染强度(EPG)分别为106.4、8. 6、0.9 和3.9,其中鞭虫卵占优势。混合感染情况比较严重,鞭虫卵和蛔虫卵的混合感染率为最高,可达44% 。

Intestinal parasites of Tianshan red deer (Cervus elaphus songaricus)in Nanshan Mountains areas in Xinjiang

The study was aimed at evaluating the status of intestinal helminth infections in the Tianshan red deer (Cervus elaphus songaricus)in Nanshan Mountains areas of Xinjiang. During about a 1 - year period-October 2010 until June 2012,and September 2012,a total of 306 faecal samples were examined by using Standard coprologic parasitological procedures. The results of the survey showed that a high prevalence of deer helminthiasis existed in Tianshan red deer and the infection rate was as high as 85. 6% . Trichuridea, Ascarididea,Coccidiosis,unknown nematode eggs and larvae were found,at prevalences of 78.1% ,56.9% ,0. 7% and 25. 8% and with their mean infection intensities 106.4,8.6,0.9 and 3.9,respectively. The predominant helminth was Trichuridea. Mixed infection by two nematodes (Trichuridea and Ascarididea)was most common with infection rate of 44% .
