Abstract:

The present study aimed to investigate some of the myxosporidian and
microsporidian parasites infecting three of the economically important marine
fishes of the Red Sea (Saurida tumbil, Pagrus pagrus and Epinephelus
chlorostigma) collected from fisherman at boat landing sites of Suez & Hurghada
cities at the Gulf of Suez & Red Sea, respectively; and one freshwater fish (Clarias
gariepinus) was collected from the River Nile at Giza Governorate in Egypt. The
examined fishes were collected monthly from October 2009 to January 2011. The
investigation of parasitic infections was carried out by means of morphologic and
morphometric characterization of these parasites. Also, the study described some
of the important developmental stages of these parasites inside fish hosts at the
ultrastructural level which are considered as key features for their classification. In
addition, molecular analyses of 18 SSU rDNA; 16 SSU rDNA and phylogenetic
relationships were applied to associate in the taxonomic characterization of myxo-
& microsporidian parasites, respectively.
