5-Hydroxytryptamine (serotonin)-immunoreactivity in the nervous system of Mesocestoides corti tetrathyridia (Cestoda: Cyclophyllidea).
An indirect immunocytochemical technique has been interfaced with confocal scanning laser microscopy to investigate the occurrence and distribution of serotoninergic (5-HT) nerve elements in Mesocestoides corti tetrathyridia. Cell bodies and nerve fibers immunoreactive to 5-HT were found concentrated in the innervation around the 4 suckers and associated commissures and in the 5 pairs of longitudinal nerve cords and their cross-connectives. Immunoreactivity was evident also in the extensive, peripheral network of fine fibers of the subtegumental region and in the plexus of varicose fibers that innervate the muscle in each of the suckers. In dividing stages of the tetrathyridium, the immunoreactive lateral nerve cords of adjoining progeny were in continuity around the base of the division cleft.
