title: Isolation of St. Louis encephalitis virus in South Brazil.
abstract: Eight strains of a flavivirus identified as St. Louis encephalitis (SLE) virus were isolated from wild rodents, birds, and sentinel mice in three locations in the State of São Paulo, Brazil from 1967--1969. No illness attributable to SLE virus infection was detected among the local inhabitants, although about 5% of the local population had neutralizing antibodies to this virus.
