Pseudoterranova decipiens

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

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. Idås, Infection with Pseudoterranova decipiens (Krabbe, 1878) larvae in cod (Gadus morhua) relative to proximity of seal colonies, Sarsia, vol. 76, pp. 227-230, 1992.

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.

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.

Sequences of LSU rDNA from 9 Pseudoterranova specimens (8 P. decipiens s.l. and 1 P. decipiens s. str.) were identical. These included individual nematodes obtained from 2 P. vitulina (HS), 3 Z. californianus (CSL), 1 Mirounga angustirostris (northern elephant seal, NES), 1 Enhydra lutris (sea otter, SO), and 1 E. jubatus (SSL) Eleven fish species from the Weddell Sea (Antarctic) were examined for infestation with anisakid nematodes. Two species of the genus Contracaecum and the sealworm Pseudoterranova decipiens were isolated from the liver and the body cavity of fish affected. Only two specimens of P. decipiens (1.4%) partly invaded the belly flaps. The following fish species were infested by P. decipiens at the. A cDNA clone encoding a 333-amino acid hemoglobin was isolated from the nematode Pseudoterranova decipiens. The protein contains an 18-amino acid hydrophobic signal sequence and has a calculated mass of 37.6 kDa in the mature form. The predicted protein reveals an internal duplication of a 154-amino acid domain (51% identity). Both domains have significant sequence homology to other primitive. Pseudoterranova decipiens and Contracaecum osculatum are important zoonotic food-borne parasites. Nonetheless, knowledge about the proteomic profiles of P. decipiens and C. osculatum third stage larvae (L3) is very limited. Therefore, we performed proteomic investigation of P. de
