During the period March to September 2000, a study was conducted in Oodi village, Kgatleng District, Botswana, to investigate the seasonal fluctuation of internal, external and blood parasites of donkeys. Twelve adult donkeys were randomly selected from a farmer with a herd of 15 donkeys. Monthly visits were made to the farmer when the donkeys were examined for parasites. The only ectoparasites recovered from the donkeys were instars of various tick species. The most prevalent tick was Rhipicephalus evertsi evertsi (98.4%), followed by Amblyomma hebraeum and Hyalomma species. The only haemoparasite seen on microscopy was Babesia equi at low parasitaemia in 26.8% of the donkeys. However, no clinical babesiosis was evident. Coprological examination showed the presence of strongyle eggs in moderate numbers. Very low numbers of coccidia oocysts were found in the faecal samples. High tick numbers and worm egg counts coincided with the warm, wet months in contrast to the low numbers recovered during the cold, dry months. An interview conducted by the authors indicated that donkeys were nutritionally marginalised by owners. Supplementary feeding was therefore recommended, especially during the winter months when grazing is poor.
2000年3月至9月期间，在博茨瓦纳卡特伦格区的奥迪村开展了一项研究，以调查驴体内、体表及血液寄生虫的季节性波动情况。从一位拥有15头驴的农户中随机挑选了12头成年驴。每月拜访该农户，对驴进行寄生虫检查。从驴身上发现的唯一体表寄生虫是各种蜱虫的幼虫。最常见的蜱虫是埃氏扇头蜱（98.4%），其次是希伯来花蜱和璃眼蜱属。显微镜检查发现的唯一血液寄生虫是巴贝斯虫，26.8%的驴感染率较低，未发现明显的临床巴贝斯虫病症状。粪便检查显示存在中等数量的圆线虫卵。粪便样本中发现极少量的球虫卵囊。蜱虫数量和虫卵计数高的时期与温暖潮湿的月份一致，而在寒冷干燥的月份数量较少。作者进行的一项访谈表明，驴在营养方面被主人边缘化。因此建议进行补充喂养，尤其是在冬季放牧条件差的时候。
