Anisakis simplex B larvae and adults occurred in the forestomach of 7 of 10 Phocoena phocoena found drowned in cod nets in the winters (November–January) of 1977–1978, 1980–1981, 1981–1982, and 1983–1984, along the Scottish east coast. A cluster of third- and fourth-stage larvae was found in one large, crater-like ulcer in the wall of the ventral "hemisphere" of the forestomach in five porpoises. A sixth infected animal had one large ulcer bearing a larval nematode cluster, plus, at a separate site in the ventral hemisphere, an aggregation of six very small ulcers, three of which contained larvae. The remaining infected porpoise harboured a large multiple ulcer at a single site in the ventral hemisphere, each of its five craters bearing a cluster of larvae. Adult male and female nematodes were apparently "free" in the forestomach lumen. One third-stage larva of Contracaecum sp. was the only other parasite found in the gastrointestinal tract of the 10 porpoises. Whiting (Merlangius merlangus) was the dominant prey item, and may have been the source of A. simplex B infection.

This study reports effects of storage at cold temperatures on behavior and survival of third-stage larvae of Terranova sp. (type HA) and Anisakis simplex (type I) in marine fishes. Snappers, caught near the Hawaiian Islands, were examined to determine whether type HA and type I larvae could migrate from the viscera of ungutted fishes into edible musculature when maintained at 12, 8, and 0°C. Our data are suggestive that both type HA and type I larvae possess the ability to migrate. Temperatures of 12, 8, and 0°C had no noticable adverse affect on viability of both larval types within fish tissues; however, both larval types were extremely sensitive to temperatures below freezing. Death of both larval types encysted within Hawaiian snappers occurred by day 4 at −5°C and within 24 h at −10, −15, and −20°C. Other type I larvae, collected from fishes (Sebastes spp.) imported to Hawaii from the western Pacific, survived for slightly longer periods at −5, −10, −15, and −20°C when compared with type I larvae from Hawaiian fishes. Subjecting Hawaiian snappers to at least −20°C for 1 d and imported rockfishes to at least −20°C for 5 d is recommended to inactivate the living anisakines before ingesting any raw fish products.

Brachiella lageniformis, hitherto known only from the Atlantic coast of Argentina, was found off the east coast of Vancouver Island, on the gills of Merluccius productus. Both male and female are described and illustrated in detail. The significance of this find for Szidat's views on the origin of the genus Merluccius is discussed. A proposal is made to suppress the genus Parabrachiella and to place all its five species (P. rostrata, P. insidiosa, P. australis, P. spinicephala, and P. incurva) in the genus Brachiella.

Development And Validation

The third-stage larvae (L3) of Anisakis simplex are the most important source of hidden allergens in seafood products. However, there exist no commercial methods for detecting Anisakis proteins in food. Furthermore, only a few methods have been validated for the detection of A. simplex in thermally processed food. The aims of our study are (i) the development and validation of high-sensitivity chemiluminescent (CL) immunoassays for the detection of A. simplex proteins in processed seafood, (ii) and A. simplex antigen detection in common seafood products from Polish markets. We developed and validated CL sandwich ELISA (S-ELISA) and CL competitive ELISA (C-ELISA) methods for A. simplex proteins detection in food, with respective detection limits of 0.5 and 5 ng/mL. The usefulness of the assays for detecting A. simplex proteins in highly processed food was evaluated by examination of autoclaved canned fish spiked with A. simplex larvae (1–8 larvae/200 g). Commercial real-time PCR was unable to detect A. simplex in autoclaved samples at all levels of enrichment with Anisakis larvae. CL-S-ELISA was used to test various types of seafood products from Polish markets. Among all tested products (n = 259), 28% were positive. A. simplex antigens were found mostly (n = 39) in smoked fish products: mackerel, herring, cod, and hake. Other positive samples were found in marinated herrings, canned cod livers, canned mackerels, and surimi sticks. In tuna, Atlantic argentine, anchovy, sardine, sprat, and squid products, A. simplex antigens were not detected. This study provides novel effective tools for the detection of A. simplex proteins in processed food and highlights the potential allergic hazards for Anisakis-sensitized Polish consumers of seafood.

Abstract Myctolaimus platypi sp. n. is described and figured. The third-stage dauer juveniles of M. platypi sp. n. were isolated from the underside of the elytra of the oak borer, Platypus quercivorus, and were reared on an Asparagine-Mannitol (A-M) agar. Specimens of adult nematodes for description and measurements were collected from a 2-week-old culture on A-M agar. The new species is characterised by having the stoma shorter than the pro-metacorpus, shape of the rounded-cylindroid pro-metacorpus, the obvious longitudinal striations on the cuticle, and thick cuticle. The male and female of the new species have a body length of ca 700-1000 μm, a value of ca 20, b value of ca 6, and c value of ca 10. Males of the new species have strongly arcuate, C-shaped spicules 71 (62-80) μm long, 29 (25-35) μm long gubernaculum with pointed distal end, and nine pairs of caudal papillae. There is no bursa. Ceratosolenus is proposed as a junior synonym of Myctolaimus and the following new combinations are also proposed: M. anoplophorae comb. n.; M. inevectus comb. n.; and M. racemosa comb. n.

ABSTRACTIndirect fluorescent antibody techniques and incubation of sectioned and ligatured larvae have been used to locate the source of azocoll-positivc secretions within the oesophagcal glands of third-stage Anisakis simplex larvae. The “excretory” system, previously suggested as a source of invasive enzymes, docs not seem to be involved. The proteolytic enzyme has trypsin-like properties and evidence is presented for its continuous synthesis during in vitro storage.

To determine abundance of larval Anisakis simplex in euphausiids of the St. Lawrence estuary, Meganyctiphanes norvegica and Thysanoessa raschii were collected at seven sites from the mouth of the Saguenay River to Baie des Outardes. Larvae were removed from euphausiids by means of a modified Baermann apparatus filled with a pepsin-HCl digest solution. Abundances of larvae in euphausiids ranged from 0 to 58.2 × 10-5. Larvae (N = 100) were in the third stage (bearing one cuticle) or moulting from the second stage to the third stage (bearing two cuticles). Euphausiids, particularly T. raschii, which represented 98% of the total euphausiids sampled, are important intermediate hosts of A. simplex in the St. Lawrence estuary. These data indicate the importance of the St. Lawrence estuary as an enzootic zone for A. simplex and thus a valuable area to study the biology and the transmission of this parasite.

ABSTRACT                The High Interest of public to Marine fish, create more demand of Slander Scad (Decapterus macrosoma). Slander Scad is one commodity that has economic value and high nutritional content. The Slander Scad is obtained from the catch of fishermen in the Nusantara Fishery Port Brondong, Lamongan. Fish that caught from the wild is likely to get a disease caused by infection of the endoparasites.worm.           The parasites that infect Slander scad probably caused by environmental factors that could decrease immune system, causing the fish easily infected by endoparasites worm such as Anisakis. This parasite is zoonotic and can infect humans, therefore, to identify and prevalence for humans who consume fish can manage properly. The purpose of this study was to identify the species of endoparasite worms that infect Slander Scad (D. Macrosoma) in Nusantara Fishery Port of Brondong, Lamongan. The research method is using a survey method through sampling at locations directly. 75 samples of Slander Scad were examined. The main parameters observed in this study are to observe the species and the prevalence of endoparasitic worm that infected Slander scad. The result of the identification of endoparasite that infected Slander Scad were analyzed descriptively and presented in the form of figures and tables. The results showed the presence of the third-stage Anisakis simplex larvae that infect the Slander Scad in the liver, intestines, gonads, muscles in the abdominal side, in the Nusantara Fishery Port of Brondong Lamongan, East Java with a total prevalence of Anisakis simplex worm was 42.67%.                               Keywords: Slander Scad, Prevalence, Anisakis simplex, and zoonotic.
