| the metazoan parasite communities of the argentinean sandperch pseudopercis semifasciata (pisces: perciformes) and their use to elucidate the stock structure of the host. | the use of parasites as biological tags allowed the identification of 3 stocks of argentinean sandperch, pseudopercis semifasciata (cuvier), in the argentine sea. a total of 100 specimens caught in 3 zones: villa gesell (37 degrees 15's, 57 degrees 23'w; n=20), miramar (38 degrees 03's, 57 degrees 30'w-38 degrees 44's, 58 degrees 44'w; n=30) and península valdes (42 degrees 00'-42 degrees 45's; n=50), were examined and 28 parasite species were found, 15 of them being new host records. both univa ... | 2009 | 19627631 |
| cold tolerance in sealworm ( pseudoterranova decipiens) due to heat-shock adaptations. | third-stage larvae of pseudoterranova decipiens commonly infect whitefish such as cod, and the parasite can be transferred to humans through lightly prepared (sushi) meals. because little is known about the nematode's cold tolerance capacity, we examined the nematode's ability to supercool, and whether or not cold acclimation could induce physiological changes that might increase its ability to tolerate freezing conditions. even if third-stage pseudoterranova decipiens larvae have some supercool ... | 2009 | 19627634 |
| risk factors for human anisakis infection and association between the geographic origins of scomber japonicus and anisakid nematodes. | it has been reported that nearly all cases of anisakiasis in japan are caused by anisakis simplex sensu stricto. to elucidate this further, we investigated the presence of anisakis type i larvae and pseudoterranova decipiens in 218 scomber japonicus fish collected from the seas of japan. anisakis type i larvae were detected in 74.3% (162/218) of the fish, and 99.8% of the anisakis type i larvae comprised a. simplex sensu stricto and anisakis pegreffii. molecular identification techniques were us ... | 2010 | 19892425 |
| sensitive detection and quantification of anisakid parasite residues in food products. | anisakids are nematodes whose larval stages are often present in fish, molluscs, and crustaceans. members of the family anisakidae belonging to the genera anisakis and pseudoterranova are implicated in human infections caused by the consumption of raw or undercooked fish. adequate cooking will kill anisakid larvae, however, killed or inactivated larvae can still cause sensitization and immunoglobulin e-dependent hypersensitivity in human. this work describes the development of dna-based tests to ... | 2010 | 19911915 |
| direct competitive enzyme-linked immunosorbent assay (elisa) for rapid screening of anisakid larvae in seafood. | anisakid larvae are one of the most important pathogenic parasites in marine products; however, simple and rapid analytical techniques for them are still very limited. in this research, based on specific rabbit polyclonal antibodies which were raised against crude extracts of anisakis larvae, purified by protein a affinity chromatography and labeled with horseradish peroxidase, a direct competitive enzyme-linked immunosorbent assay (elisa) was developed and validated for detection of anisakid la ... | 2010 | 20355125 |
