Figure 3.

Neighbor-joining tree of Onchocerca spp. and unknown filarial larvae based on the 12S rRNA gene sequences. Bootstrap values and posterior probabilities (NJ/ML/BI) are shown above or near the branches. A dash indicates that support values are less than 50% (for NJ and ML) or 0.50 (for BI). The scale bar represents 0.02 substitutions per nucleotide position. Red triangles, blue circles, and white circle with a black border before each specimen designate the specimens obtained from this study and also indicate the vector blackfly species.
