肩突硬蜱是重要的医学节肢动物传播媒介,可将多种病原体传播给人类。在这些蜱中观察到形态异常,包括矮小、缺腿、多腿和雌雄同体。在这项研究中,我们报告的存在下,两个肛门在实验室饲养的I。肩突若虫允许蜱虫幼虫以小鼠为食并蜕皮至成虫。在其中一只刚蜕皮的雌猴中观察到两个肛门。立体和扫描电子显微镜证实存在两个肛门在一个若虫在一个单一的肛门沟。本报告证实了双肛门在I.肩胛肌在线版本包含补充材料,可通过10.1186/s13071-021-04757-8获得。
Ixodes scapularis ticks are medically important arthropod vectors that transmit several pathogens to humans. The observations of morphological abnormalities, including nanism, missing leg, extra leg, and gynandromorphism, have been reported in these ticks. In this study, we report the presence of two anuses in a laboratory-reared I. scapularis nymph. Larval ticks were allowed to feed on mice and to molt to nymphs. Two anuses were observed in one of the freshly molted nymphs. Stereo and scanning electron microscopy confirmed the presence of two anuses in one nymph within a single anal groove. This report confirms the rare occurrence of double anus in I. scapularis. The online version contains supplementary material available at 10.1186/s13071-021-04757-8.
