1998年1月至2002年12月，我们采集了乌干达西部红尾猴(CerCopithecus Ascanius)、蓝猴(CerCopithecus Mitis)、L猴(Cercopithecus Lhoesti)和长尾猴(Cercopithecus Aethiops)4种自由放养个体的粪便样本，以定量研究胃肠道寄生虫的流行情况。用硝酸钠浮选法和粪便沉淀法分离虫卵、幼虫和原虫包囊。对蠕虫寄生虫进行了鉴定，并确定了所有4种寄生虫的感染率。共培养促进了对线虫的鉴定。对于最常见的物种，红尾鱼，我们记录了原生动物寄生虫的流行情况，并检查了季节和宿主性别对感染流行的影响。共检出6种线虫(Strongyloids fulleborni，Oreatagostomum sp.，不明Strongyloids，Trichuris sp.，Streptopharagus sp.和Enterobius sp.)，1种线虫(Bertiella sp.)，1种吸虫(Dmicrocoeliidae)，5种原生动物(结肠内阿米巴、溶组织内阿米巴、布氏IoDameoba buschlii、蓝氏贾第鞭毛虫和松材线虫)。感染红尾鱼的任何寄生虫物种的感染季节模式都不是很明显。虽然男性和女性的患病率没有差异，但只有成年女性感染了食道口线虫。和富勒伯尼(S.Fulleborni)。
From January 1998 to December 2002, we collected 293 fecal samples from free-ranging individuals of the 4 guenon species of western Uganda, i.e., redtail guenons (Cercopithecus ascanius), blue monkeys (Cercopithecus mitis), l'hoesti monkeys (Cercopithecus lhoesti), and vervet monkeys (Cercopithecus aethiops), to quantify the prevalence of gastrointestinal parasites. Helminth eggs, larvae, and protozoan cysts were isolated by sodium nitrate flotation and fecal sedimentation. Helminth parasites were identified, and infection prevalence was determined for all 4 guenon species. Coprocultures facilitated identification of strongylate nematodes. For the most common species, the redtail guenon, we documented prevalence of protozoan parasites and examined the effect of season and host sex on infection prevalence. Six nematodes (Strongyloides fulleborni, Oesophagostomum sp., unidentified strongyle, Trichuris sp., Streptopharagus sp., and Enterobius sp.), 1 cestode (Bertiella sp.), 1 trematode (Dicrocoeliidae), and 5 protozoans (Entamoeba coli, Entamoeba histolytica, Iodameoba butschlii, Giardia lamblia, and Chilomastix mesnili) were detected. Seasonal patterns of infection were not readily apparent for any parasite species infecting redtail guenons. Although prevalence never differed between male and female guenons, only adult females were infected with Oesophagostomum sp. and S. fulleborni.
