Camallanida

Camallanida is a family of nematodes from the order Spirurida. The family includes several species that are parasitic on fish and other aquatic animals. The family was first described by Railliet and Henry in 1915.

Taxonomy

The family Camallanida includes several genera, including Camallanus, Procamallanus, Spirocamallanus, and Paracamallanus. The genus Camallanus is the most well-known and includes several species that are important parasites of fish.

Morphology

Members of the family Camallanida are characterized by their unique mouthparts, which include a pair of lateral lobes and a central cone. The males have a pair of spicules and a gubernaculum, which are used in mating.

Life cycle

The life cycle of Camallanida nematodes involves several stages, including eggs, larvae, and adults. The eggs are released into the water by the adult female, and they hatch into larvae after a period of development. The larvae are then ingested by a suitable host, where they develop into adults.

Pathogenicity

Camallanida nematodes can cause disease in their hosts, including fish and other aquatic animals. The symptoms of infection can include weight loss, reduced growth, and in severe cases, death.

Treatment and control

Treatment of Camallanida infections typically involves the use of anthelmintic drugs. Control measures can include good hygiene practices and regular monitoring of fish populations for signs of infection.
