Rhesus macaques ( are distributed across Nepal in close association with humans and with a high probability of sharing of soil-transmitted intestinal helminth parasites. This study was carried out to determine the prevalence, richness and risk factors of gastrointestinal (GI) helminth parasites among rhesus macaques and humans in the Daunne Forest area, a community managed forest in the central mid-hills of Nepal. A total of 190 fecal samples, including 120 samples from rhesus macaques residing around the Daunne Devi Temple and in the surrounding forest, and 70 from local people, were microscopically examined by direct wet mount, floatation and sedimentation methods. Seasonal and age-sex based variations in helminth parasite prevalence were analyzed. Among the rhesus macaques, the total parasite prevalence was 39.2 %. sp. accounted for the highest prevalence (19.17 %) followed by sp. (13.33 %), hookworm (10.83 %) and sp. (4.17 %). Among the humans, (11.3 %) was the only parasite detected. The Sorenson's coefficient of similarity of GI parasites between the macaques and local people at the generic level was 0.4. Mean parasite richness for the macaques was 1.21 ± 0.41 (SD) per infected sample. Parasite prevalence in the summer season (41.4 %) was higher than in the winter season (36 %). Adult macaques (41.67 %) had higher GI parasite prevalence than the young (30.77 %) and infants (27.27 %). Among the adult macaques, the prevalence rate was significantly higher (=0.005) in females (52.46 %) than in males (22.86 %). Our results indicate that the temple rhesus macaques have a high prevalence of GI helminth parasites and could pose a potential zoonotic risk. As such, the need for routine monitoring and an effective management strategy is essential.
恒河猴分布于尼泊尔,与人类密切接触,很有可能共享土壤传播的肠道蠕虫寄生虫。本研究旨在确定尼泊尔中部中山地区社区管理的道讷森林地区恒河猴和人类胃肠道(GI)蠕虫寄生虫的患病率、丰富度及风险因素。共采集了190份粪便样本,其中包括120份来自居住在道讷德维寺周围及周边森林的恒河猴样本,以及70份来自当地居民的样本,采用直接湿涂片法、漂浮法和沉淀法进行显微镜检查。分析了蠕虫寄生虫患病率的季节性及基于年龄和性别的差异。在恒河猴中,总寄生虫患病率为39.2%。某属寄生虫患病率最高(19.17%),其次是另一属寄生虫(13.33%)、钩虫(10.83%)和又一属寄生虫(4.17%)。在人类中,仅检测到某寄生虫(11.3%)。恒河猴和当地居民在属水平上胃肠道寄生虫的索伦森相似系数为0.4。每例感染样本中恒河猴的平均寄生虫丰富度为1.21±0.41(标准差)。夏季寄生虫患病率(41.4%)高于冬季(36%)。成年恒河猴(41.67%)的胃肠道寄生虫患病率高于幼年恒河猴(30.77%)和幼猴(27.27%)。在成年恒河猴中,雌性(52.46%)的患病率显著高于雄性(22.86%)(P=0.005)。我们的结果表明,寺庙恒河猴胃肠道蠕虫寄生虫患病率很高,可能构成潜在的人畜共患病风险。因此,进行常规监测和制定有效的管理策略至关重要。
