Abstract This study had been applied on a total of (360) fishes of 9 species, 8 of them were marine fishes with a total of (320): (40 Scomberomorous cavalla, 40 Sparus aurata, 40 Siganus revulatus, 40 Pomadasys stridens, 40 Argyrosomus regius, 40 Dicentrarchus labrax, 40 Sardinella spp. and 40 Epinephelus aeneus.) and one was fresh water fish with a total of (40): (Oreochromis niloticus). They have been randomly and seasonally collected from Port said and Ismailia Governorate with different body weights and lengths from March 2022 to February 2023. The total prevalence of infection was (48.1%), The highest percentage was in Siganus revulatus (90%) followed by Pomadasys stridens (87.5%), Dicentrarchus labrax (72.5%), Scomberomorous cavalla (52.5%), Sparus aurata and Argyrosomus regius was the same percentage (37.5%), Sardinella spp. (27.5%), Epinephelus aeneus (17.5%), then the lowest percentage was in Oreochromis niloticus (10%). The isolated parasites were trematode monogeneans with prevalence (59.5%): (Pricea multae, Cemocotyle carangis, Furnestinia echeneis, Tetrancistrum indicum, Paranella diplodae, Microcotyle chrysophrii, Diplectanum spp., Diplectanum aequans, Diplectanum squamatum, Diplectanum copiosum and Calceostoma Calceostoma), trematode digeneans with prevalence (27%): (Acanthostomum spiniceps, Gonocerca trematomi, Erilepturus hamati, Metadena crassulata, EMC in liver, EMC in muscle, Transversotrema spp., Opisthadena bodegensis, Opisthadena dimidia, Hexangium sigani, Clinostomum complanatum metacercaria and Tangiopsis chinensis). PCR was used for confirmation of Pricea multae the 28S rDNA sequences which give product at an approximately 300 bp. Also, the phylogenetic analysis for this trematode was done. |
