Summary This study determined the diversity and seasonality of parasites species of the African clawed frog, Xenopus laevis (Daudin, 1802), from three localities, namely Modjadjikloof, Mokopane and University of Limpopo, Limpopo Province, South Africa. A total of seven parasite species were collected and identified. They included two nematodes, Camallanus kaapstaadi Southwell & Kirshner, 1937 and Batrachocamallanus slomei (Southwell & Kirshner, 1937), a monogenean, Protopolystoma xenopodis (Price, 1943), a cestode, Cephalochlamys namaquensis (Cohn, 1906), a protozoan, Trichodina xenopodos Fantham, 1924, two digeneans, Progonimodiscus doyeri Ortlepp, 1926 and Dollfuschella rodhaini Vercammen-Grandjean, 1960. The most common and abundant parasite species by far were Cm. kaapstaadi, B. slomei and Cp. namaquensis, with Cm. kaapstaadi, B. slomei present in all localities. Trichodina xenopodos was a rare species, only present in host populations from Modjadjiskloof. Modjadjiskloof had the highest species richness (all seven parasite species) followed by Mokopane (five parasite species) and University of Limpopo (3 parasite species). There were also higher infection levels (prevalence and mean intensity) of Cm. kaapstaadi, B. slomei, Cp. namaquensis and Pt. xenopodis in hosts from Modjadjiskloof while Pd. doyeri and D. rodhaini infection levels were greater in Mokopane. The variability between localities shows that parasites with heteroxenous life cycles are more strongly associated with more pristine habitats. The variability in calculated indices (prevalence and mean intensity) also suggests that the occurrence of some of the parasites is affected by season, favouring higher infection rates during summer. This suggests that temperature has a direct role in the reproductive and developmental processes of these parasites. Neither length nor sex had an influence on the prevalence or intensity of parasites.

南非林波波省选定栖息地的非洲爪蟾（两栖类：Pipidae）寄生虫的多样性及其季节性感染率

总结 本研究确定了非洲爪蛙 Xenopus laevis (Daudin, 1802) 寄生虫物种的多样性和季节性，它们来自三个地点，即 Modjadjikloof、Mokopane 和南非林波波省的林波波大学。共收集并鉴定了七种寄生虫。它们包括两种线虫，Camallanus kaapstaadi Southwell & Kirshner，1937 年和 Batrachocamallanus slomei（Southwell & Kirshner，1937 年），一种单殖吸虫，原多口虫（价格，1943 年），一种绦虫，Cephalochlamys namaquensis，三足动物，1937 Fantham，1924 年，两个 digeneans，Progonimodiscus doyeri Ortlepp，1926 年和 Dollfuschella rodhaini Vercammen-Grandjean，1960 年。迄今为止最常见和最丰富的寄生虫物种是 Cm。kaapstaadi、B. slomei 和 Cp。namaquensis，与厘米。卡普斯塔迪，B. slomei 存在于各地。Trichodina xenopodos 是一种稀有物种，仅存在于 Modjadjiskloof 的宿主种群中。Modjadjiskloof 的物种丰富度最高（所有七种寄生虫），其次是 Mokopane（五种寄生虫）和林波波大学（三种寄生虫）。Cm 的感染水平（流行率和平均强度）也更高。kaapstaadi, B. slomei, Cp. namaquensis 和 Pt. 来自 Modjadjiskloof 的宿主中的爪蟾，而 Pd。Mokopane 的 doyeri 和 D. rodhaini 感染水平更高。地区之间的变异性表明，具有异质生命周期的寄生虫与更原始的栖息地更密切相关。计算指数（流行率和平均强度）的变化也表明某些寄生虫的发生受季节影响，有利于夏季较高的感染率。这表明温度在这些寄生虫的繁殖和发育过程中具有直接作用。长度和性别均不影响寄生虫的流行或强度。
