Six hundred and thirty-three faecal samples were randomly collected and examined for ova and cysts of intestinal parasites from five groups of hamadryas baboons of different population densities, with different human contact and in different ecological conditions (Al-Baha, Turabah and Al-Taif in south-western and Al-Rihat and Al-Akhal in north-western Saudi Arabia). Nine parasites were recorded (Giardia lamblia, Entamoeba histolytica, Escherichia coli, Balantidium coli, Enterobius sp., Trichuris sp., Hookworm, Hymenolepis nana and Schistosoma mansoni) in 274 samples (43.28%). The prevalence of parasites was high (36.0-58.5%) in areas of mild, cool climatic conditions, where baboons were at high density and had maximum human contact. However, in an area (Al-Akhal) of hot, dry climatic conditions, low baboon density and minimum human contact, the parasites' prevalence was very low (9.5%). The concentration of parasites (ova or cysts per g of faeces) was medium. Post-mortem examination of 24, 20, 19 and 13 baboons from Al-Baha, Al-Taif, Turabah and Al-Rihat revealed most of the parasites recorded in random faecal samples at prevalence rates of 37.5, 30.0, 36.0 and 23.0% respectively. The overall prevalence rate was 32.9%. Most of the parasites recorded in baboons were also recorded in humans in the areas of study.
从五组不同种群密度、不同人类接触程度且处于不同生态条件下（沙特阿拉伯西南部的艾卜哈、图拉巴赫和泰夫，以及西北部的里哈特和阿卡勒）的阿拉伯狒狒中随机采集了633份粪便样本，检测肠道寄生虫的虫卵和包囊。在274份样本（43.28%）中记录到9种寄生虫（蓝氏贾第鞭毛虫、溶组织内阿米巴、大肠埃希菌、结肠小袋纤毛虫、蛲虫属、鞭虫属、钩虫、微小膜壳绦虫和曼氏血吸虫）。在气候温和凉爽、狒狒密度高且与人类接触最多的地区，寄生虫感染率很高（36.0 - 58.5%）。然而，在气候炎热干燥、狒狒密度低且与人类接触最少的阿卡勒地区，寄生虫感染率非常低（9.5%）。寄生虫浓度（每克粪便中的虫卵或包囊数）为中等。对来自艾卜哈、泰夫、图拉巴赫和里哈特的24只、20只、19只和13只狒狒进行的尸检显示，随机粪便样本中记录的大多数寄生虫的感染率分别为37.5%、30.0%、36.0%和23.0%。总体感染率为32.9%。在狒狒中记录到的大多数寄生虫在研究地区的人类中也有记录。
