Reptiles were known to serve as paratenic hosts for Centrorhynchus (Acanthocephala: Centrorhynchidae) in Korea, but the infection course in experimental animals was not elucidated yet. In this study, the tiger keelback snakes (Rhabdophis tigrinus) were collected and digested with artificial pepsin solution, and the larvae of Centrorhynchus were recovered from them. Then, the collected larvae were orally infected to rats for developmental observations. In rats, all the larvae were observed outside the intestine on day 3 post-infection (PI), including the mesentery and abdominal muscles. As for the development in rats, the ovary of Centrorhynchus sp. was observed at day 15 PI, and the cement glands were 3 in number. Based on the morphological characteristics, including the arrangement of proboscis hooks, these larvae proved to be a species of Centrorhynchus, and more studies were needed for species identification.
在韩国，已知爬行动物是Centrorhynchus（棘头虫纲：Centrorhynchidae）的转续宿主，但实验动物的感染过程尚未阐明。在本研究中，收集了虎斑颈槽蛇（Rhabdophis tigrinus）并用人工胃蛋白酶溶液进行消化，从中回收了Centrorhynchus的幼虫。然后，将收集到的幼虫经口感染大鼠以进行发育观察。在大鼠中，感染后第3天（PI）在肠道外观察到所有幼虫，包括肠系膜和腹部肌肉。至于在大鼠体内的发育情况，在感染后第15天观察到Centrorhynchus sp.的卵巢，粘腺数量为3个。根据包括吻钩排列在内的形态特征，这些幼虫被证明是Centrorhynchus的一个物种，物种鉴定还需要更多研究。
