Abstract Share this page

Observations with the light microscope and the scanning and transmission electron microscopes have shown that the anterior end of Monocotyle spiremae has 8 slit-like apertures on the ventrolateral margins at each side of the mouth. Gland cells located next to the pharynx produce rod-shaped secretory bodies that are conveyed in ducts that open on to the surfaces of rounded lobes inside “reservoirs” behind each ventral, slit-like aperture. Rod-shaped secretory bodies are extruded into the “reservoirs” and appear to combine and form a homogeneous secretion which may bond the ventrolateral regions of the head of the parasite to a substrate. At no stage, however, were intact rods observed outside the duct endings. Gland cells that produce an ovoid secretory body also supply the head of M. spiremae, but ducts from these open dorsal and anterior to the mouth in a region where the parasite is not known to attach. There appears to be little or no chance for the ventral rods and the dorsal ovoid secretion to mix. This is the first record of a monogenean parasite with a single type of secretion supplying the ventral surfaces of the anterior end. The rods in M. spiremae differ in some respects from the rod-shaped bodies recorded previously among gyrodactylid, dactylogyrid, capsalid and acanthocotylid monogeneans.
