人类异尖线虫病是由食用生的、腌制的或未煮熟的鱼和鱿鱼引起的，这些鱼和鱿鱼感染了1845年Dujardin异尖线虫属的线虫。从食品安全的角度出发，对日本海域海鱼中异尖线虫的分布进行了研究。从6个地点采集7种鱼类进行异尖线虫感染检查。形态学和分子（ITS区和mtDNA cox2基因）鉴定显示，在单尖异尖线虫的3个兄弟种中存在A. simplex sensu strict （s.s.）和A. pegreffii。为了更好地了解异尖线虫在日本海域的分布情况，我们将分布数据与以往的研究结果进行了比对。异尖线虫种的分布具有地域特异性而非宿主特异性，特别是在单尖线虫和pegreffii这两个主要种之间。单一异尖线虫主要分布在日本北部至太平洋沿岸的鱼类中，而pegreffii主要分布在日本海至东海沿岸的鱼类中。2011爱思唯尔爱尔兰有限公司版权所有。
Human anisakiasis is caused by the consumption of raw, marinated or undercooked fish and squid infected with nematodes of the genus Anisakis Dujardin, 1845. In view of food safety, this study was carried out to examine the distribution of Anisakis species in marine fishes within Japanese waters. Seven fish species from six localities were collected and examined for Anisakis infection. Morphological and molecular (ITS region and mtDNA cox2 gene) characterization revealed the presence of two, among the three sibling species of Anisakis simplex, viz. A. simplex sensu strict (s.s.) and A. pegreffii. Distribution data were collated with the results from the previous researches to better understand Anisakis distribution in Japanese waters. Distributions of Anisakis species were found to be locality-specific rather than host-specific, particularly between the two major species, A. simplex s.s. and A. pegreffii. Anisakis simplex s.s. is mainly found in fishes from northern Japan to Pacific sides, whereas A. pegreffii is in fishes from the Sea of Japan to East China Sea sides. (C) 2011 Elsevier Ireland Ltd.
