The present work represents a new host, the terrestrial hermit crab, Coenobita scaevola Forskal and a new locality records for the larval nematode, Ascarophis from Safaga city. The results showed a direct relationship between host size (carapace length) and the prevalence rate of infected specimens. Larval nematodes were rarely found in specimens smaller than 17.0 mm in carapace length. Also, the fecundity of infected crabs was less than that of normal ones. Two types of host tissue response to infection were represented by muscular and haemocytic capsules around the larval nematodes.
本研究报告了一种新的宿主——陆生寄居蟹（Coenobita scaevola Forskal），以及来自萨法加市的幼虫线虫（Ascarophis）的新产地记录。结果表明，宿主大小（头胸甲长度）与感染标本的患病率之间存在直接关系。在头胸甲长度小于17.0毫米的标本中很少发现幼虫线虫。此外，受感染螃蟹的繁殖力低于正常螃蟹。宿主组织对感染的两种反应表现为幼虫线虫周围的肌肉和血细胞包囊。
