title: Occurrence and Intensity of Anisakid Nematode Larvae in Some Commercially Important Fish Species in Persian Gulf.
abstract: 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, (Saurida tumbil), Japanese thread fin bream (Nemipterus japonicus), crocodile longtom (Tylosurus crocodilus crocodiles) and longfin trevally (Carangoides armatus) from the Persian Gulf of Iran.
  
  
  RESULTS
  The collected larvae were identified mainly as the third larval stage (L3) ofHysterothylaciumlarval type A, B and C,Anisakissp.,Raphidascarissp.,Pseudoterranovasp. andPhilometrasp. (Nematoda: Philometridae). The prevalence of Anisakid larvae infection of examined fishes was 97.2% inN. japonicus, 90.3% inS. tumbil,20.5% in crocodile longtom and 5.5% in longfin trevally.Anisakistype III for the first time was different fromAnisakistype I andAnisakistype II.
  
  
  CONCLUSIONS
  Zoonotic anisakids by high prevalence in edible fish could be a health hazard for people. So health practices should be considered in these areas.
