项目摘要
(1) The life cycle and developmental stages of some parasitic copepods have been newly revealed by the present investigation. The number of post-naupliar stages of caligids is evidently six. Reinfection of adults is implied in some caligids. The whole life cycle of a pennelid Peniculus minuticaudae infecting fins of filefish is totally disclosed: the hatching stage is copepodids; no host switching is found. It is likely that fish fins are feasibly infected by infective stages of parasitic copepods but so limited for fecundity of adult females. (2) Results of bioassay indicate that attractants for the infective copepodid of Caligus fugu is water-soluble. At least 10 genes coding secretory proteins or enzymes were obtained by suppression subtractive hybridization, which was applied to isolate genes expressed higher in fins compared to skin. These are likely to be candidate genes related to the attachment site-specificity of the infective stage.
(1)新发现了一些寄生桡足类的生活史和发育阶段。无节幼体后阶段的数量显然是六个。成虫的再感染在一些哈里吉斯中隐含着。全面揭示了细尾叶蝉侵染鱼鳍的整个生活史:孵化期为桡足类,未发现寄主切换。很可能,寄生的桡足类感染阶段的鱼鳍是可行的,但对成年雌性的繁殖力是有限的。(2)生物测定结果表明,河豚感染性桡足类引诱剂为水溶性引诱剂。通过抑制性消减杂交获得了至少10个分泌蛋白或酶的编码基因,并将其应用于分离在鳍中比皮肤更高表达的基因。这些可能是与感染阶段的附着部位特异性相关的候选基因。
