| Abstract | ||||
| The study dealt with anisakid nematode larvae (L3) in a commercially important marine fish Pagrus pagrus purchased from different fish markets at 3 localities: El-Matareya, El-Zaitoun and, Saray El-Kobba, Cairo. Anisakid nematodes are zoonotic fish-borne parasites that may transmit to human by consuming raw fish containing the third stage larvae encapsulated in the fish muscles caused a serious disease Anisakidosis. The symptoms of that disease are nausea, diarrhea, vomiting and severe abdominal pain. Four species of L3 larvae were detected; Hysterothylacium sp., Raphidascaris sp., Contracaecum sp. and Terranova sp. Identification of the larvae depended basically upon the structure of the cephalic region, oesophogus shape, ventricular appendage, tail end and presence or absence of mucron. Two-hundred and thirtythree larvae were isolated from 80/140 (56.4%) examined fish. The hosts were collected from November 2019 to April 2020. Larvae were measured in relation to host's weight, sex and infection prevalence. The results statistically showed that larvae prevalence and intensity were varied significantly in relation to host's sex and weight. | ||||
