Abstract：
:The formaldehyde-induced fluorescence technique had shown 5-hydroxytryptamine-containing enteric neurons in the intestine of the teleost Platycephalus bassensis, but did not reveal such neurons in the intestine of Tetractenos glaber or Anguilla australis. Re-examination of these animals with 5-hydroxytryptamine immunohistochemistry showed immunoreactive enteric neurons in the intestine of all three teleost species. The 5-hydroxytryptamine-containing enteric neurons showed essentially the same morphology in all species examined: the somata were situated in the myenteric plexus, extending down into the circular muscle layer, but none were found in the submucosa; processes were found in the myenteric plexus, the circular muscle layer and the lamina propria. It was concluded that the neurons may innervate the muscle layers or the mucosal epithelium, but were unlikely to be interneurons. In a range of teleosts, enterochromaffin cells were found in the intestine of only those species in which the formaldehyde technique did not visualize neuronal 5-hydroxytryptamine. Available evidence suggests that, in vertebrates, 5-HT-containing enterochromaffin cells are lacking only where there is an innervation of the gut mucosa by nerve fibres containing high concentrations of 5-HT.
