Fig. 5From: Prevalence and molecular characterization of Dirofilaria immitis in road killed canids of northern IranPhylogenetic tree of 18S rRNA gene sequences of the Dirofilaria immitis obtained in this study (▲) and reference sequences retrieved from GenBank. The tree was constructed based on the maximum likelihood method and the Tamura 3-parameter model in MEGA6. Ascaris sp. sequence was used as the out group. Bootstrap values lower than 50 were omittedBack to article page
