Philometridae is a family of nematodes belonging to the order Rhabditida. [1] All Philometridae are obligate tissue parasites of fish.

Life cycle

Philometridae cycle between two hosts: Cyclopoida (small crustaceans) as an intermediate host, and various fish as a definitive host. [2] First-stage larvae are ejected into the water, and develop to the third stage if they're eaten by a cyclopoid. Once the copepod is eaten by a fish, the larvae develop into adults and mate. Pregnant females migrate to a final site just under the fish's skin, in the swim bladder, or in the coelom; males die soon after mating and in many Philometridae species they have never been described.

<i>Anisakis</i> Genus of parasitic nematodes

Anisakis is a genus of parasitic nematodes that have life cycles involving fish and marine mammals. They are infective to humans and cause anisakiasis. People who produce immunoglobulin E in response to this parasite may subsequently have an allergic reaction, including anaphylaxis, after eating fish infected with Anisakis species.

Capillaria plica is a parasitic nematode which is most often found in the urinary bladder, and occasionally in the kidneys, of dogs and foxes. It has also been found in the domestic cat, and various wild mammals. Its presence usually produces no clinical symptoms, but in some cases, it leads to hematuria, cystitis, or difficulty in urination.

<i>Philometra</i> Genus of roundworms

Philometra is a genus of nematodes, which are parasites of marine and freshwater fishes. The genus was erected by Oronzio Gabriele Costa in 1845.

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.

This species is characterized mainly by: length of spicules and length and structure of its gubernaculum; structure of male caudal end; body size; location in host and types of hosts.

Philometroides eleutheronemae is a species of parasitic nematode of fishes, infecting the gonads of marine perciform fishes off the eastern Indian coast. It was first found in the fourfinger threadfin, Eleutheronema tetradactylum. It is distinguished from its cogenerates by the gubernaculum structure in males, as well as the shape and structure of the females' cephalic and caudal ends, and their oesophagus.
