Abstract

The objectives of this study were to extend our knowledge of the geographic distribution and rodent host range of arenaviruses in North America. Sera from wild rodents collected from the southern and western United States were tested for antibody against Tamiami, Pichinde, Junin, and lymphocytic choriomeningitis viruses, using an indirect fluorescent antibody test. Antibody to at least one arenavirus was found in 220 (3.1%) of 7,106 rodents tested. The antibody-positive animals included from Florida and Texas; from Arizona, Colorado, and New Mexico; and from California: from Arizona, New Mexico, and Utah; from Arizona and New Mexico; and and from Florida. seropositive for Tamiami virus were found only in Florida (156 [27.0%] of 578 tested), although 463 hispid cotton rats from outside that state were examined. High-titered antibodies to Tamiami virus were present in sera from , (geometric mean antibody titer [GMAT] of 1:792), whereas sera from spp. reacted at high titer to both Tamiami (GMAT = 1:905) and Pichinde (GMAT = 1:433) viruses. The results suggest that arenaviruses are widely distributed in the southern United States and that one or more indigenous arenaviruses are associated with spp. in North America.
