Abstract

Trypanorhynch Cestodes Infecting Mediterranean Sea Fishes, Egypt: Callitetrarhynchus gracilis Larvae (Pintner, 1931) as a Bio-indicator of Heavy Metals Pollution

Highlights

Fish is one of the most important sources among the food products of animal origin because of their content of high quality biological animal protein, lipids, vitamins, essential fatty acids and several kinds of minerals [1,2].Fish parasites recorded to have a negative impact on the commercial fisheries industry [3],among them Trypanorhynchid cestodes (Order Trypanorhyncha) are considered as one of the main groups which follow three or four host life cycles, before reaching the final host [4]
Muscle of fish is the tissue commonly chosen because of the implications it carries for human consumption and health risk. Such studies are imperative since rapid industrialization and urbanization during the last two decades have affected the quality of the Egyptian coastal environment along the Mediterranean Sea [9]
Out of the 150 investigated specimens, 63 (42%) were found to be infected with trypanorhynchid species larvae

Summary

Introduction

Fish parasites recorded to have a negative impact on the commercial fisheries industry [3],among them Trypanorhynchid cestodes (Order Trypanorhyncha) are considered as one of the main groups which follow three or four host life cycles, before reaching the final host [4] They are typically found in the stomach and intestine of sharks and rays, whilst their larval forms infect a wide variety of marine invertebrates and mainly use fishes as intermediate or paratenic hosts [4]. Only few cases of accidental human infections by trypanorhynchs have been reported [4], these worms may cause allergic reactions [6] Despite their worldwide distribution and importance for commercial fisheries, trypanorhynchids are still a relatively poorly studied group. There has been increasing interest in the interrelationship between parasitism and pollution, especially in aquatic habitat and to the role of parasites as bioindicator of heavy metals pollution [10,11,12]
