Agents Encountered during Arboviral Ecological Studies: Tampa Bay Area, Florida, 1963 to 1970

Abstract
This communication presents a summary of all virus isolations made at the Epidemiology Research Center from specimens gathered throughout the Tampa Bay area of Florida from 1963 to 1970. A total of 697 isolations was made. Seven different virus groups were represented with three arbovirus groups accounting for 608 (87%) of all isolates: California encephalitis virus group, 313 isolates (44.9%), 220 Keystone and 93 Trivittatus; Bunyamwera group, 179 isolates (25.6%), all Tensaw; and Group A, 115 isolates (16.5%), 94 Eastern equine encephalitis, and 21 Western equine encephalitis. Minimal infection ratios and isolation trends are discussed.
