Figure 1.

Phylogenetic analysis showing Oropouche virus (OROV) genotypes detected by reverse transcription-polymerase chain reaction (RT-PCR) in cerebrospinal fluids of three patients having meningoencephalitis (bold-italics). This neighbor-joining consensus tree was inferred from 1,000 bootstrap replicates. The percentage of replicate trees, which clustered together in the bootstrap testing, is shown next to the branches. Kimura 2-parameter nucleotide substitution model was chosen as the best-fit after a run on FindModel using all 28 models implemented.
