A marine kinetoplastid flagellate, Cryptobia eilatica n. sp., is described from the gills of cultured gilt-head sea bream Sparus aurata L. and wild black-spot sea bream Diplodus noct (Valenciennes) in the Red Sea. The trophozoite is elongated and lacks a contractile vacuole and undulating membrane. The body averages 13.5 x 4.1 microns, anterior flagellum 9.7 microns and free portion of recurrent flagellum 15.2 microns. The ultrastructural features of the species exhibit great similarity to various previously studied Cryptobiids. Cryptobia eilatica trophozoites feed on bacteria, show a preference for the branchial interlamellar crypts, and attach to the host epithelium by means of the recurrent flagellum. Neither penetration into the epithelial cells, nor any direct damage to host tissue was observed. Cryptobia eliatica inhabits a purely marine habitat, but its trophozoite tolerates salinities as low as 10 ppt.
一种海洋动基体鞭毛虫，新种红海隐鞭虫（Cryptobia eilatica n. sp.），是从红海养殖的金头鲷（Sparus aurata L.）和野生黑点鲷（Diplodus noct (Valenciennes)）的鳃中发现的。滋养体呈细长形，没有收缩泡和波动膜。虫体平均大小为13.5×4.1微米，前鞭毛长9.7微米，回返鞭毛的游离部分长15.2微米。该物种的超微结构特征与之前研究的各种隐鞭虫非常相似。红海隐鞭虫滋养体以细菌为食，偏好鳃瓣间隐窝，并通过回返鞭毛附着在宿主上皮细胞上。未观察到其侵入上皮细胞或对宿主组织造成任何直接损伤。红海隐鞭虫栖息于纯海洋环境，但其滋养体可耐受低至10ppt的盐度。
