In many areas of The Gambia, West Africa, population crowding in a degraded environment has forced close interactions of diurnal primate species with humans. We assessed intestinal parasitic infection prevalence and diversity in 4 diurnal non-human primate (NHP) species, and across 13 sampling sites. The effect of human activity, determined by the human activity index, and NHP group size on parasite richness was assessed using a generalized linear mixed model (GLMM). The most common protozoa identified were (30%) and (25%). The most common helminths were (11%), spp. (9%) and (9%). Two of six (6%) spp. infections detected sequenced as (both in ). The more arboreal trended towards a lower prevalence of intestinal parasites, although this was not statistically significant (χ = 0.105). Human activity or group size did not have any significant effect on parasite richness for ( = 0.161 and = 0.603) or ( = 0.817 and = 0.607, respectively). There were insufficient observations to fit a GLMM to or . Our reports present the richness and diversity of intestinal parasites in 4 diurnal NHPs in The Gambia, West Africa. Despite desertification and habitat loss, our results indicate that the prevalence and diversity of intestinal parasites in Gambian NHPs are seemingly unaffected by human activity. Further investigation with a larger dataset is required to better elucidate these findings.
在西非冈比亚的许多地区，人口在退化环境中的拥挤促使昼行性灵长类物种与人类密切互动。我们评估了4种昼行性非人灵长类（NHP）物种以及13个采样点的肠道寄生虫感染率和多样性。使用广义线性混合模型（GLMM）评估了由人类活动指数确定的人类活动以及NHP群体规模对寄生虫丰富度的影响。鉴定出的最常见原生动物是（30%）和（25%）。最常见的蠕虫是（11%）、 spp.（9%）和（9%）。检测到的6种 spp.感染中有2种测序为（均在中）。树栖性更强的趋向于肠道寄生虫感染率较低，尽管这在统计学上不显著（χ = 0.105）。人类活动或群体规模对（ = 0.161和 = 0.603）或（分别为 = 0.817和 = 0.607）的寄生虫丰富度没有任何显著影响。没有足够的观测数据来对或拟合GLMM。我们的报告展示了西非冈比亚4种昼行性NHP肠道寄生虫的丰富度和多样性。尽管存在荒漠化和栖息地丧失的情况，但我们的结果表明，冈比亚NHP肠道寄生虫的感染率和多样性似乎不受人类活动的影响。需要用更大的数据集进行进一步调查，以更好地阐明这些发现。
