A coprological survey of intestinal parasites of wild chimpanzees (Pan t. troglodytes) and western lowland gorillas (Gorilla g. gorilla) was carried out in the Lopé Reserve in central Gabon. Most samples (69%) were positive but the prevalence of intestinal parasites in the 61 gorilla samples (84%) was higher than in the 66 chimpanzee samples (56%). At least 11 species of parasite were observed: six protozoan, one trematode and at least four nematodes. Six of the species were found in gorillas and chimpanzees but the remainder only occurred in chimpanzees. All but one parasite occurred at low prevalences. Entodiniomorph ciliates, which occurred frequently in both ape species (particularly in gorillas) in the Lopé survey and in all previous coprological surveys of wild apes, may be symbionts involved in cellulose digestion. The dietary and behavioural strategies of wild primates that serve to reduce infection by pathogenic parasites are reviewed.
在加蓬中部的洛佩自然保护区，对野生黑猩猩（Pan t. troglodytes）和西部低地大猩猩（Gorilla g. gorilla）的肠道寄生虫进行了粪便学调查。大多数样本（69%）呈阳性，但61份大猩猩样本中肠道寄生虫的患病率（84%）高于66份黑猩猩样本（56%）。至少观察到11种寄生虫：6种原生动物、1种吸虫和至少4种线虫。其中6种在大猩猩和黑猩猩中都有发现，但其余的只出现在黑猩猩中。除一种寄生虫外，其他寄生虫的患病率都很低。内毛虫纤毛虫在洛佩调查中以及之前所有对野生猿类的粪便学调查中，在这两种猿类（尤其是大猩猩）中都频繁出现，可能是参与纤维素消化的共生体。本文综述了野生灵长类动物为减少致病性寄生虫感染而采取的饮食和行为策略。
