title: Attachment-inducing capacities of fish skin epithelial extracts on oncomiracidia of Benedenia seriolae (Monogenea: Capsalidae).
abstract: Attachment-inducing capacities of skin epithelial extracts of yellowtail, Japanese flounder and red sea bream on oncomiracidia of the monogenean Benedenia seriolae were examined. Clear differences were not detected in the capacity among the fish species, although B. seriolae infects only yellowtail and its congeners in Seriola. This suggests that either the capacity is not host specific or host-specific attachment-inducing capacity cannot be detected by the assay method. Further, the attachment-inducing capacities were suppressed by wheat-germ lectin and concanavalin A in skin epithelial extracts of Japanese flounder and yellowtail, respectively. This suggests that some sugar-related chemical substances existing in fish epithelia induce the attachment of B. seriolae oncomiracidia.
