BACKGROUND
Anisakid nematodes are common parasites of fish, mammals, fish-eating birds, and reptiles with a worldwide distribution, causing diseases in human, fish and important economic losses.
METHODS
A preliminary epidemiological study was carried out on Anisakid nematodes larvae in some commercially important fish species to evaluate the anisakid nematode larvae from greater lizardfish, (, Japanese thread fin bream (), crocodile longtom () and longfin trevally () from the Persian Gulf of Iran.
RESULTS
The collected larvae were identified mainly as the third larval stage (L3) of larval type A, B and C, sp., sp., sp. and sp. (Nematoda: Philometridae). The prevalence of Anisakid larvae infection of examined fishes was 97.2% in , 90.3% in 20.5% in crocodile longtom and 5.5% in longfin trevally. type III for the first time was different from type I and type II.
DISCUSSION
Zoonotic anisakids by high prevalence in edible fish could be a health hazard for people. So health practices should be considered in these areas.
背景
异尖线虫是鱼类、哺乳动物、食鱼鸟类和爬行动物常见的寄生虫，分布于世界各地，可导致人类患病，给鱼类带来疾病并造成重大经济损失。
方法
对一些具有重要商业价值的鱼类品种中的异尖线虫幼虫进行了初步流行病学研究，以评估来自伊朗波斯湾的大头狗母鱼、日本金线鱼、鳄形叉尾鹤鱵和高体若鲹的异尖线虫幼虫。
结果
收集到的幼虫主要鉴定为幼虫A、B和C型的第三幼虫期（L3），分别为、、和（线虫纲：嗜子宫线虫科）。所检查鱼类的异尖线虫幼虫感染率在大头狗母鱼中为97.2%，在日本金线鱼中为90.3%，在鳄形叉尾鹤鱵中为20.5%，在高体若鲹中为5.5%。首次发现III型与I型和II型不同。
讨论
可食用鱼类中高感染率的人兽共患异尖线虫可能对人类健康构成危害。因此，在这些地区应考虑采取卫生措施。
