从1997年8月到2003年7月，我们从乌干达3种疣猴的自由放养个体中收集了2,103份粪便样本，这3种疣猴是濒危的红疣猴（Piliocolobus tephrosceles）、东部黑白色疣猴（Colobus guereza）和安哥拉黑白色疣猴（C.安哥拉）-以确定胃肠道寄生虫的流行情况。蠕虫卵，幼虫和原生动物包囊分离硝酸钠浮选和粪便沉淀。共生菌有助于蠕虫的识别。7种线虫（Strongyloides fullerborni，S.粪口菌属（Stercoralis）、食道口菌属（Oesophagostomum sp.）一种不明的圆线虫鞭虫属蛔虫，和Colobenterobius sp.），I cestode（Bertiella sp.），1种吸虫（双腔科）和3种原生动物（大肠内阿米巴、大肠埃希氏菌）。和贾第鞭毛虫）。感染疣猴的寄生虫物种的季节性感染模式并不明显。S.与成年雌性红疣猴相比，成年雄性红疣猴的富勒氏菌感染率更高，但在年龄和性别类别之间，我的其他共享寄生虫物种的患病率没有差异。
From August 1997 to July 2003, we collected 2,103 fecal samples from free-ranging individuals of the 3 colobus monkey species of Uganda-the endangered red colobus (Piliocolobus tephrosceles), the eastern black-and-white colobus (Colobus guereza), and the Angolan black-and-white colobus (C. angolensis)-to identify and determine the prevalence of gastrointestinal parasites. Helminth eggs, larvae, and protozoan cysts were isolated by sodium nitrate flotation and fecal sedimentation. Coprocultures facilitated identification of helminths. Seven nematodes (Strongyloides fulleborni, S. stercoralis, Oesophagostomum sp., an unidentified strongyle, Trichuris sp., Ascaris sp., and Colobenterobius sp.), I cestode (Bertiella sp.), I trematode (Dicrocoeliidae), and 3 protozoans (Entamoeba coli, E. histolytica, and Giardia lamblia) were detected. Seasonal patterns of infection were not apparent for my parasite species infecting colobus monkeys. Prevalence of S. fulleborni was higher in adult male compared to adult female red colobus, but prevalence did not differ for,my other shared parasite species between age and sex classes.
