title: Molecular evidence of St. Louis encephalitis virus infection in patients in Buenos Aires, Argentina.
abstract: We report two cases of St. Louis encephalitis where the virus was detected in patients' sera directly by molecular techniques allowing subsequent typing. Phylogenetic analysis of both samples showed that NS5 sequences clustered with viruses previously classified as genotype III.
