Abstract

ABSTRACT: During August 2019, 2 stump-tailed geckos, Gehyra mutilata were collected by hand from 2 sites within Peninsular Malaysia and examined for coccidia. Both were found to be passing oocysts of Eimeria cf. cicaki Else and Colley, 1975. Oocysts are subspheroidal to ellipsoidal, with a smooth bilayered wall, measure 19.4 ×16.1 µm, and have a length/width (L/W) ratio of 1.2; a micropyle and oocyst residuum are absent, but a single polar granule is present. Sporocysts are ellipsoidal and measure 7.3 × 6.7 µm, L/W 1.1; Stieda, sub-Stieda, and para-Stieda bodies are absent. The sporocyst residuum is composed of large dispersed granules lying between the sporozoites. The current isolate appears to be morphologically divergent from the specimens as originally described. Previously reported endogenous development shows this coccidian should be transferred to the genus Acroeimeria Paperna and Landsberg, 1989. Here, we provide additional morphological information on the coccidian, as well as the first photomicrographs of the sporulated oocysts of the species.

摘要：2019年8月，在马来西亚半岛的两个地点手工采集了2只残尾壁虎Gehyra damenta，并对其进行了球虫检查。两者都被发现是通过艾美耳球虫卵囊。参见cikaki Else和Colley，1975。卵囊为近卵球形至椭球形，具有光滑的双层壁，尺寸为19.4×16.1µm，长宽比为1.2；不存在微孔和卵囊残留物，但存在单个极性颗粒。孢子囊是椭圆形的，尺寸为7.3×6.7µm，长宽1.1；斯蒂达、亚斯蒂达和副斯蒂达机构不存在。孢子囊残留物由位于孢子之间的大的分散颗粒组成。目前的隔离物在形态上似乎与最初描述的标本不同。先前报道的内源性发育表明，这种球虫应该转移到Acroeimeria Paperna属和Landsberg，1989年。在这里，我们提供了关于球虫的额外形态学信息，以及该物种孢子卵囊的第一张显微照片。

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
