چکیده

This study provides the first report of presence Coolia malayensis in Mediterranean Sea, co-occurring with C. monotis. Isolated strains from Gulf Gabès, Tunisia (South-eastern Mediterranean) were identified by morphological characterization and phylogenetic analysis. Examination light scanning electron microscopy revealed no significant differences between Tunisian isolates other geographically distant monotis malayensis. Phylogenetic trees based on ITS1-5.8S-ITS2 D1‒D3/28S rDNA sequences showed that clustered others Atlantic whereas isolate branched Pacific Atlantic, therefore revealing geographical trend among populations. Ultrastructural analyses transmission numerous vesicles containing spirally coiled fibers both cells, which we speculate to be involved mucus production.
