Evolutionary, ecological and taxonomic relationship between anboviruses of Florida, U.S.A. and Brazil

RESUMO

A few arbovirus and related viruses genotypic and phenotypic corollaries in both subtropical south Florida and tropical Brazil. Their occurrences in these areas may to intercontinental movement by circumstances or, most likely, to divergent virus evolution in divergently evolving hosts. It is counterintuitive that ecologic similarities and the presence of rodents and certain genera of mosquitoes alone would be sufficient to bring about convergent evolution and account for nucleotide similarities of such close order. Although relatively few, pairings such as these may indicate common ancestry and subsequent evolution
