Fig. 3. : neighbour-joining analysis used to identify Alphavirus sequences detected in mosquitoes (420 nt, nSP4). A dendrogram was constructed using representative sequences from the Alphavirus genus available in GenBank. The sequences detected were similar to representative Venezuelan equine encephalitis virus (VEEV) sequences. Abbreviations: WEEV (Western equine encephalitis virus); EEEV (Eastern equine encephalitis virus); AV (Aura virus); SINV (Sindbis virus); OV (Ockelbo virus); BFV (Barmah Forest virus); MBV (Middelburg virus); ONNV (o’nyong nyong virus); RRV (Ross River virus); and SFV (Semliki Forest virus). GenBank accession numbers are followed by the abbreviated names of viruses. The sequences of arboviruses detected in this study are presented with a GenBank accession number, followed by the mosquito species in which they were detected (in bold). SBV: San Bernardo del Viento, Córdoba (Colombia).
