Maximum likelihood tree of NFLG sequences of the BF cluster and of references of CRF_BFs from the Southern Cone of South America and of subtypes. Names of sequences obtained by us are in bold type. In database sequences located in the BF cluster, the country of sample collection is indicated before the virus name with the two-letter ISO country code. In reference sequences, the subtype or CRF is indicated before the virus name. Only bootstrap values ≥ 80% are shown.
