Larval Anisakis simplex B (Nematoda: Ascaridoidea) of short-¢nned squid (Cephalopoda: Ommastrephidae) in north-west Spain

چکیده
The role of the ommastrephid squids Illex coindetii and Todaropsis eblanae (Mollusca: Cephalopoda) collected fromtwo areas in the north-eastern Atlantic waters (north-west Spain) as hosts for larval ascaridoid nematodes was examined from November 1992 to November 1993.The morphology, morphometric growth, population dynamics and electrophoretic identi¢cation of the anisakid nematodes was described.The correspondence of Anisakis type I larvae recovered from both squid species within the sibling species Anisakis simplex B is con¢rmed by comparative data on morphology, morphometry, and genetic evidences. Almost all somatic structures showed progressive and continuous allometric growth corresponding with increase in worm length. Seasonal changes in parasite population levels were evident inboth sampling areas.

Anisakis simplex (Nematoda: Ascaridoidea): Formation of Immunogenic Attachment Caps in Pigs
Anisakis simplex larvae maintained in simple salt solutions were observed attached to the surface of a petri dish in vitro by a translucent cap. Previous reports attributed the formation of these caps to contributions by human serum. Dissolved caps reacted in Western blot with the sera of rabbits sensitized with A simplex excretory-secretory products. Caps were demonstrated in vivo in the mucos...

Parasitic nematodes are known as important pathogens that cause problems for human and animal health. Some of them naturally inhabit the marine environment, where they are widespread and can be found in a variety of different hosts. Food-borne zoonoses via aquatic animals are most often linked to anisakid nematodes of the genera Anisakis Dujardin, 1845, Contracaecum Railliet and Henry, 1912, an...
متن کاملPrevalence of anisakin nematodes in fish from Southern Baltic Sea.
Nematodes from the superfamily Ascaridoidea (families Anisakidae and Raphidascarididae) are worldwide distributed parasites. Their live cycles include many species of water invertebrates and teleostean fish as intermediate hosts, and fish, sea mammals or fish-eating birds being definitive hosts. Humans can be infected with some of these parasites after consumption of raw or wrongly processed fi...

Cephalopods play an important role in the transfer of parasites through the food web. They are second and third intermediate hosts for larval stages of digeneans, cestodes, and nematodes. The final hosts are usually fishes, sea birds, and marine mammals (Hochberg, 1990). Nevertheless, the interactions of cephalopods and their parasites are still poorly understood, and almost nothing is know abo...

Anisakidae larvae can cause anisakiasis when ingested by humans. Although several groups have reported a gastrointestinal Anisakis allergy among people in Spain and Japan, our report is the first to summarize the clinical features of 10 Anisakis allergy cases in Korea. We enrolled 10 Korean patients (6 men and 4 women) who complained of aggravated allergic symptoms after ingesting raw fish or s...
