The Anisakidae are a family of intestinal nematodes (roundworms). The larvae of these worms can cause anisakiasis when ingested by humans, in raw or insufficiently cooked fish. Anisakidae worms can infect many species of fish, birds, mammals and even reptiles. [1] They have some traits that are common with other parasites.
Contracaecum larvae can infect humans, the human disease caused by infection of Anisakid nematodes such as Contracaecum is called anisakiasis (or anisakidosis) which is a painful and severe condition with infection usually being caused by the consumption of raw or undercooked fish which are host to the third stage larvae.
The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
In order to avoid or kill the infective larva living in fish muscle, one must boil the fish first for a minimum of five minutes, placed in a solution of vinegar and 4% acetic acid for a period of 5.5 hours, or just to avoid raw or undercooked fish, always being sure to cook fresh water fish thoroughly.
The Anisakis simplex is a parasitic roundworm classified under the phylum Nematoda. [2] [5] It possesses the typical characteristics of its phylum, including an unsegmented, cylindrical body that occasionally fills up with fluids and allows it to swim freely. [5]
In most aquarium tanks, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental ...
The free-living nematode Panagrellus redivivus (sour paste nematode, [2] or beer mat nematode from its occurrence in constantly moist felt beer mats), [1] is known to many aquarium enthusiasts and fish keepers as the microworm. It is a tiny roundworm used as the first food for larger kinds of newly-hatched fish, such as larval common carp. [3]
Myleusnema bicornis is an intestinal parasite of Myleus ternetzi, or "Ternetz's Silver Dollar", a freshwater Characoid fish commonly found in the French Guiana river. [1] M. bicornis has several unusual morphological characteristics, namely the two postcloacal "horns" in the posterior of males, and a separate elongated cephalic region (head) that may be extended and retracted.
