Pseudoterranova is a genus of parasitic nematodes with an aquatic life cycle within family Anisakidae. The lifecycle of Pseudoterranova spp. involves marine mammals, pinnipeds (sea lions, seals and walruses) as definitive hosts, planktonic or benthic crustaceans as intermediate hosts and fish which act as second intermediate or paratenic hosts Pseudoterranova decipiens Name Synonyms Ascaris decipiens Krabbe, 1878 Homonyms Pseudoterranova decipiens (Krabbe, 1878) Common names Sælorm in Danish Torskeorm in Danish cod or seal worm in English Bibliographic References.

Anisakis simplex larvae measure 2-3 cm by 0.3-0.6 mm and Pseudoterranova dicepiens 2-3 cm by 0.3-1.2 mm. They are found in the muscle and body cavity of marine fish and squid
Pseudoterranova decipiens is listed as a rare disease by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Pseudoterranova decipiens, or a subtype of Pseudoterranova decipiens, affects less than 200,000 people in the US population The Pseudoterranova decipiens complex is generally more geographically restricted than Anisakis spp., occurring in cold-water coastal environments such as the Northern Atlantic, the Arctic and South (Antarctic) Oceans, Japan, and off the southern coast of Chile. Contracecum osculatum complex species also occur in these colder regions Emerging Pseudoterranova decipiens (Krabbe, 1878) problems in Baltic cod, Gadus morhua L., associated with grey seal colonization of spawning ground
The P. decipiens species complex consists of at least 5 sibling species (genetically but not morphologically distinguishable): P. decipiens sensu stricto, P. azarasi, P. cattani, P. krabbei, and P. bulbosa. In northern Japan, human infection with Pseudoterranova spp. is not rare; by the mid-1990s, as many as 769 cases had been reported Figure 3 Phylogenetic tree based on the Maximum Likelihood of the partial cytochrome c oxidase subunit II gene, showing the relationship of Pseudoterranova decipiens (bold) with others species of Pseudoterranova. Numbers (percentage) on the branches indicate 5,000 bootstrap replicates On the basis of such differences, the nomenclatural designation for the two species is discussed. The names Pseudoterranova krabbein. sp. and P. decipiens(sensu stricto) are proposed for species A and B, respectively. Morphological and genetic differentiation between the two species is shown using multivariate analysis A species of parasitic nematodes in the family Anisakidae. The lifecycle of P. decipiens involves crustaceans as the first intermediate host, fish or squids as the second intermediate host, and marine mammals as the definitive host. Humans may become infested by eating undercooked fish and may also develop anaphylaxis upon contact with the worm in properly prepared fish

Latin: ·catching, trapping, deceiving, cheating Definition from Wiktionary, the free dictionar The anisakid nematode Pseudoterranova decipiens, known as the sealworm or cod worm, can infect the flesh of several fish species. The parasite causes cosmetic problems for the fish industry and can cause abdominal discomfort if consumed by humans. There are only scattered studies on the abundance or distribution of the sealworm in fish and seals in the Baltic Sea Larval sealworm (Pseudoterranova decipiens) infections were surveyed in the fillets and napes of 28 065 Canadian plaice (Hippoglossoides platessoides), 31-40 cm in length, collected throughout Atlantic Canada between February 1980 and August 1990. Samples were taken from 11 locations in a 1980-1982 survey, and from 38 to 55 locations in 1983-1984, 1985-1986, 1987-1988, and 1989-1990 surveys
Pseudoterranova decipiens (P. decipiens) is the second most common Anisakidae found in humans [1, 4]. While rare in Europe, this nematode species is more frequently found in North America, Japan, Korea, and Chile [ 5 , 6 , 7 , 8 , 9 ] Pseudoterranova decipiens belongs to the Invertebrates group.

Pseudoterranova decipiens can be considered a cosmo-politan species, occurring in many aquatic hosts from the boreal to the Antarctic region (Kerstan 1991; Palm et al. 1994). P. decipiens matures in seals, and the ﬁrst intermediate hosts are crustaceans, such as copepods, amphipods, shrimps, and isopods (Marcogliese 1996) T. Jensen and K.

In each case a larva was found in the throat five and six days after the consumption of insufficiently cooked filets of the common catfish Anarhicas lupus that were bought fresh in a fish store. In both cases the larva had already developed from 3rd to the 4th stage during the time of infection The ascaridoid nematode Pseudoterranova decipiens has a complex life‐cycle. Adult worms reproduce in the stomach of grey seals, Halichoerus grypus, and other pinnipeds, and the larvae are found encysted in the musculature of Atlantic cod, a common host.An increase in infection levels in Canadian, Icelandic and Norwegian cod stocks over the last decade has been attributed to recent increases.
Anisakis simplex, Pseudoterranova decipiens, and Contracaecum osculatum third-stage larvae (L3) are fish-borne nematodes that can cause human anisakidosis. Although A. simplex is a known source of allergens, knowledge about the allergic potential of P. decipiens and C. osculatum is limited Demersal fish were sampled over 3 years to describe sealworm Pseudoterranova decipiens infection levels in relation to the size of a local colony of common seals Phoca vitulina in Hvaler, Oslofjord, Norway. More than 2000 fish were examined for worms, and five fish species were found to be infected, cod Gadus morhua, four‐bearded rockling Enchelyopus cimbrius, plaice Pleuronectes platessa.
Recently, molecular genetic techniques have shown that the main species, Anisakis simplex and Pseudoterranova decipiens, are in fact species groups with distinct geographic and biologic characteristics (3,4).

sealworms (Pseudoterranova decipiens) seems to be rather independent of the number of common seals in the outer Oslofjord. Large samples of some fish species and stomachs of common seals have been collected by several students under the leadership of Morten Bronndal in the last years Pseudoterranova decipiens (Krabbe, 1878) Gibson, 1983 - Ocean Biogeographic Information Syste In fact, human infections with Pseudoterranova spp. is far from rare in northern Japan, amounting to 769 cases by the mid-1990s and 7 cases of P. decipiens have occurred in Chile [8,9]. Recently, P. decipiens was classified, by the molecular method, into 5 sibling species, i.e., P. decipiens sensu stricto, P. azarasi , P. cattani , P. krabbei , and P. bulbosa [ 10 ]

The model predicts the total amount of food eaten by a fish to reach its size. In young fish grow this linear in time and average parasite burdens are predicted to increase with the cube of.
Most human infections are caused by Anisakis simplex and Pseudoterranova decipiens (previously known as Phocanema decipiens). Other members of the family Anisakidae less commonly responsible for human infections include additional members of the A. simplex complex (eg, Anisakis pegreffi ) and Pseudoterranov a complex, as well as A. physeteris, Contracaecum species, and Thynnascaris species [ 7 , 8 ] include anisakis and pseudoterranova.

Spatial and temporal trends of larval sealworm (Pseudoterranova decipiens) infection in eastern Canadian groundfish were monitored in an indicator host, Canadian plaice (Hippoglossoides platessoides), in the 31 to 40 cm length range. Between February 1993 and September 1999, a total of 8,482 plaice were collected from 33 locations in Canadian. The present study provides further data on the occurrence of Pseudoterranova decipiens in fish from two different sampling sites in the Antarctic. A total of 690 fish belonging to 33 species from the eastern Weddell Sea and 322 fish belonging to 12 species from the South Shetland Islands were examined. Altogether, 23 fish species were found to be infested and 11 new host records could be. Pseudoterranova decipiens. After removal of the larva, the patient returned home and followed up uneventfully. DISCUSSION As already noted, this case of P. decipiens infection is the 13th discovered in Korea. Since Anisakis type I larvae have been im-plicated in most cases of human anisakiasis in Korea, othe
