*SLEV, St. Louis encephalitis virus; SM, suckling mouse. Twelve strains collected over 5 decades in Florida were sequenced for phylogenetic analysis. Four South American strains of SLEV were acquired by the Bureau of Laboratories–Tampa before 1972 and sequenced as representative of genotype V SLEV. One control strain (TBH-28) was analyzed and used as a positive control in reverse transcription–PCR and sequencing assays. TBH-28 represents a Florida isolate of SLEV made during the 1960s, but the envelope sequence was previously published (GenBank accession no. AF205469).
