Abstract

A total of 385 Red Sea coral reef fish representing three species; Broom tail wrasse (), Blacktip grouper () and Rabbit fish ( sp.). were examined for the presence of nematode species. The eggs of species were isolated and identified only from the The total prevalence of sp. infestation were 69.5%. The highest prevalence was observed in winter and the lowest in spring and summer. The prevalence was increased in correlation with fish body weight. Fully developed eggs of species were dark brown embryonated, elongated, with slightly protruding plugs. A high density of sp. eggs with different developmental stages packed the epithelial layer of the gas bladder. The surrounding tissue of gas bladder was hemorrhagic and sometimes necrotic associated with chronic inflammatory cell infiltration. This is the first record of species infestation in Broom tail wrasse Red Sea coral reef fishes.

摘要

共对代表三个物种的385条红海珊瑚礁鱼进行了检查,包括帚尾濑鱼()、黑鳍石斑鱼()和兔鱼(属),以检测线虫物种的存在情况。仅从[此处原文缺失相关物种名称]中分离并鉴定出了该物种的卵。[此处原文缺失相关线虫物种名称]感染的总患病率为69.5%。冬季患病率最高,春季和夏季最低。患病率与鱼的体重呈正相关。[此处原文缺失相关物种名称]完全发育的卵呈深褐色,具胚胎,呈椭圆形,带有略微突出的塞子。高密度的处于不同发育阶段的[此处原文缺失相关线虫物种名称]卵堆积在鳔的上皮层。鳔周围组织出血,有时坏死,并伴有慢性炎性细胞浸润。这是红海珊瑚礁鱼类帚尾濑鱼中[此处原文缺失相关线虫物种名称]感染的首次记录。
