Fig. 3From: Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2 synthases in physiology and host–parasite interactionsLocalization of LsPGES3 by in situ analysis of an adult female salmon louse (Lepeophtheirus salmonis). Dark coloring indicates the presence of transcripts. a Overview of the louse with positive staining seen in ovaries, oocytes and subepidermal tissue.
