Immunocytochemical demonstration of SALMFamide(Sl)-like immunoreactivity in the nervous system of two marine platyhelminth parasites, Diclidophora merlangi and Grillotia erinaceus

: The localization and distribution of SALMF amide (S1)-immunoreactivity (IR) in the nervous system of both the trematode, Diclidophora merlangi, and the cestode, Grillotia erinaceus, have been determined by an indirect immunofluorescent technique. Immunostaining was widespread in the central (CNS) and peripheral (PNS) nervous systems of both species. Antigen pre-absorption studies indicated that the results obtained do suggest S1-like immunostaining and not cross-reactivity with other peptides, in particular, neuropeptide F (NPF) and FMRF amide.
