Abstract
Fish is one of the best foods for humans because of its high nutritional value and easy for digestion, but on the other hand, fish has an important role in the transmission of some parasitic diseases to humans when eaten raw or undercooked. Therefore, this study was conducted to clarify the role of some marine water fish in the transfer of some parasites to humans and discuss the health importance of these parasites.
A total of 205 marine fish samples including two different species were collected from fish markets at Sharkia governorate from October, 2018 till the end of May, 2019 which represented 105 red porgy or common seabream (P. pagrus) and 100 lizard fish (S. undosquamis) and examined for presence of different anisakid nematodes.
This study revealed that the total number of infected fish with anisakid nematode was 96 fish with total prevalence of 46.83%. The highest prevalence of total anisakid nematode was recorded for S. undosqamis (58%) than P. pagrus (36.19%). Mann-Whitney U test indicated that the prevalence of Anisakis and Pseudoterranova infection were significantly higher in S. undosquamis than in P. pagrus (P˂ 0.05). The sites of infection were peritoneal cavity, pyloric caeca, stomach, large intestine, gonads and liver surface. Four anisakid species were identified in this study; Anisakis spp., Pseudoterranova spp., Hysterothylacium spp. L3 and Hysterothylacium spp. adult. The last worm was only encountered in stomach and large intestine of P. pagrus.
