MORPHOLOGICAL AND ULTRASTRUCTURAL STUDY ON TYPE I AND TYPE II THIRD STAGE LARVAE OF ANISAKIS SIMPLEX FROM RED SEA FISHES FROM HURGHADA, EGYPT

Abstract

Study of the prevalence and identification of the juveniles of Anisaxis spp. in the marine fishes is of great value for biologists and medical parasitologists. In this study, Red Sea fishes at Hurghada, Egypt were examined for adult and larval helminthes. Among others, Anisakis simplex third stage larvae; type I & type II were identified from three fish hosts; Caranx sexfasciatus, Cephalopholis miniata and Variola louti. The prevalence of larvae was reported and their light and SEM morphological characters were illustrated. The encountered larvae were compared with previously described ones from Red Sea fishes from Egypt, Yemen and Arabia Saudi, and their zoonotic pathogenesis was discussed.
