Parasites of Anisakidae Family--Geographical Distribution and Threat to Human Health

Nematodes of the Anisakidae family are important parasites that can cause anisakiasis--human parasitic infection of gastrointestinal tract. Allergic symptoms can arise as secondary immune response after infection by living parasite. In the life cycle of these parasites, intermediate, definitive and paratenic hosts （fish） might occur. In most cases, human anisakiasis is caused by consumption of fish which are infected with the larvae of the Anisakidae family. The purpose of the article was to assess the definitive host, the geographical spread of the parasites and the risk associated with consumption of raw fish and fishery products. Furthermore, this article describes symptoms and treatment of anisakiasis and kinds of preventive measures that can be taken to prevent anisakiasis.

近海鱼类异尖科幼线虫形态分类学研究——Ⅱ.北部湾部分

在对从北部湾捕获海鱼的异尖科(Anisakidae)幼线虫感染状况进行初步调查的基础上,作了形态分类学研究。共检海鱼29种,134只标本,其中简单异尖线虫3期幼虫的感染率达30.6％,且大部分阳性鱼种的感染率在50％以上。此外尚检获宫脂线虫(Hysterothylacium)属3期幼虫2型:C_1型和C_5型,其中C_1型为初次报告。另检出伪新地蛔线虫(Pseudoterranova)属幼虫1型。
