Abstract
Superficial stellate cells of an unknown origin were detected on the epidermis of juvenile mahi mahi, Coryphaena hippurus L., up to 60 days of age. The cells occurred in large numbers, and were detected in both wild and cultured fish. International authorities were unable to identify the organism and there was no pathology associated with the presence of the cells on the skin. Because of the fine cytoplasmic interdigitations between the organism and the host cell, and the close ecological association with both wild and cultured juveniles examined, it was thought that the cells could possibly be highly modified skin cells. We report here that the spinous cells possess DNA sequences encoding 16S subunit ribosomal RNA genes distinct from those of mahi mahi, and also that restriction enzyme digests of genomic DNA from the spinous cells and from mahi mahi produced distinct patterns after electrophoretic separation. This suggests that the spinous cells are a bizarre commensal organism displaying a close physical and ecological association with the fish host.
