Philometra
''Philometra'' is a genus of nematodes, which are parasites of marine and freshwater fishes. The genus was erected by Oronzio Gabriele Costa in 1845. Species in this genus are worldwide. They parasitize the body cavities, tissues and ovaries of both marine and freshwater fishes. When still in the larval stages, these worms move to the body cavities or subcutaneous tissues in the host. This migration can cause damage to skeletal joints, result in internal bleeding, and inflame visceral organs. Emaciation and lowered growth rates may result from this. Infestation produces nodules under the skin. When the worms are in the adult or juvenile stage, these nodules may be visible between the rays of the fins or may cause the scales to raise up. Larger nodules may be the result of gravid females which may rupture the skin surface. Once ruptured, the female disintegrates. This allows the release of the live larvae into the water. This wound on the fish then heals, leaving almost no scarr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philometra Priacanthi
''Philometra priacanthi'' is a species of parasitic nematode of fishes. Its name is derived from its host species, '' Priacanthus hamrur''. It possesses dorsal lamella-like structures on the distal part of its gubernaculum, which can also be found on other of its cogenerates. The only species with a dorsal protuberance near the gubernaculum's end is ''P. priacanthi'', however. '' P. lateolabracis'' can be distinguished from the former by the lateral caudal mounds separated dorsally, narrower lamella-like structures on its gubernaculum, shorter spicules, and by the testis extending anteriorly. Other gonad-infecting species differ from this one by possessing a smooth gubernaculum, and their spicules being of different lengths. Seven gonad-infecting species of ''Philometra'' can be distinguished from ''P. priacanthi'' by their host types, as well as by geographical distribution. Description This description is based on a male specimen. It presents a filiform, whitish body, me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
