These three parks in North-east Thailand, Kosamphi Forest Park, Kumphawapi Monkey Garden, and Dong Ling Don Chao Pu Park, are internationally recognized for sheltering long-tailed macaques. Overfeeding by tourists and locals significantly increases the frequency of human-macaque encounters. Being close to each other raises the chances of contracting gastrointestinal (GI) parasites. This study was designed to estimate the prevalence and range of GI parasite infections in long-tailed macaques among the three major natural habitats.
Three hundred fecal samples were collected from long-tailed macaques, with 100 samples from each of the three study sites. The samples underwent Formalin-ethyl acetate concentration technique examination. Parasites were identified based on their morphology and size as observed under a light microscope.
About 66.67% of the population had GI parasitic infection. had the highest occurrence (41.66%), whereas spp. (24.33%), spp. (18.33%), (10.33%), and (2.33%) followed next in prevalence. A higher rate of single infections (41%) was reported compared to mixed infections (25.66%). At Dong Ling Don Chao Pu Park, the prevalence rate of in long-tailed macaques was 70%, markedly higher than those reported at the other two study sites. In these areas, the first known case of infection occurred in long-tailed macaques. In the Kumphawapi Monkey Garden, the prevalence of spp. and spp. infections was significantly greater (45% and 28%, respectively) compared to the other two areas.
In northeast Thailand, long-tailed macaques are predominantly infected with , causing GI protozoal infections. In this primate population of the region, and species are common helminths. This study offers new knowledge on parasitic loads in Thai long-tailed macaques, essential for devising effective One Health approaches to prevent and manage zoonotic diseases.
泰国东北部的考桑皮森林公园、孔帕瓦皮猴园和董灵顿超普公园这三个公园因庇护长尾猕猴而在国际上享有声誉。游客和当地人的过度投喂显著增加了人与猕猴接触的频率。彼此相邻增加了感染胃肠道（GI）寄生虫的几率。本研究旨在估计这三个主要自然栖息地中长尾猕猴胃肠道寄生虫感染的患病率和范围。
从长尾猕猴身上采集了300份粪便样本，三个研究地点各采集100份。样本采用福尔马林 - 乙酸乙酯浓缩技术进行检查。根据在光学显微镜下观察到的形态和大小鉴定寄生虫。
约66.67%的长尾猕猴群体感染了胃肠道寄生虫。 感染率最高（41.66%），其次是 属（24.33%）、 属（18.33%）、 （10.33%）和 （2.33%）。报告的单一感染率（41%）高于混合感染率（25.66%）。在董灵顿超普公园，长尾猕猴中 的患病率为70%，明显高于其他两个研究地点的报告患病率。在这些地区，首次发现长尾猕猴感染 。在孔帕瓦皮猴园， 属和 属感染率明显高于其他两个地区（分别为45%和28%）。
在泰国东北部，长尾猕猴主要感染 ，导致胃肠道原生动物感染。在该地区的这种灵长类动物群体中， 和 物种是常见的蠕虫。本研究提供了关于泰国长尾猕猴寄生虫负荷的新知识，这对于制定有效的“同一健康”方法来预防和管理人畜共患病至关重要。
