Fig. (4) Phylogenetic tree of COI gene subunit I from the isolated Oestrus ovis larvae of the referred patients to “K” hospital. COI gene sequences were aligned using MEGA 6.0 software based on the ClustalW method against characterized sequences from Lucilia sericata, Oestrus ovis, Anopheles stephensi, Culex quinquefasciatus, and Chrysomya megacephala. The phylogenetic analysis revealed that the sequence of our samples had the highest similarity to Oestrus ovis. The accession numbers of different sequences appear in front of each branch.
