In reptiles, infection with Cryptosporidium parasite can be lethal, especially in species of family Eublepharidae such as Eublepharis macularius and Goniurosaurus splendes species. We investigated the presence of Cryptosporidium spp. in wild reptiles, especially Goniurosaurus spp., in five islands of Japan. Nested PCR was performed to detect Cryptosporidium spp. in 38 fecal samples of 9 reptile species from five islands of Japan, and 3 (3/8) positive samples of Goniurosaurus kuroiwae sengokui from Tokashikijima, Okinawa Prefecture were detected. A BLAST search of the detected gene sequences revealed that the all 3 samples were identified as Cryptosporidium serpentis, a reptile-specific Cryptosporidium parasite. This is the first record of Cryptosporidium from a wild Goniurosaurus species in Japan and worldwide.
在爬行动物中,感染隐孢子虫寄生虫可能是致命的,特别是在睑虎科和沙蜥科等科的物种中,如睑虎和变色沙蜥。我们调查了日本五个岛屿上野生爬行动物,特别是变色沙蜥,是否存在隐孢子虫。我们对来自日本五个岛屿的 9 种爬行动物的 38 份粪便样本进行巢式 PCR 检测,在冲绳县渡嘉敷岛的 3 只(3/8)黑疣变色蜥中检测到阳性样本。对检测到的基因序列进行 BLAST 搜索显示,所有 3 个样本均被鉴定为隐孢子虫蛇种,这是一种专门感染爬行动物的隐孢子虫寄生虫。这是在日本和全球范围内首次从野生变色沙蜥中记录到隐孢子虫。
