prevalence of antibodies to arenaviruses in rodents from the southern and western united states: evidence for an arenavirus associated with the genus neotoma.	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 mus musc ...	1996	8686773
population genetics of the hispid cotton rat (sigmodon hispidus): patterns of genetic diversity at the major histocompatibility complex.	the hispid cotton rat, sigmodon hispidus, is a common rodent widely distributed across the southern usa and south into south america. to characterize major histocompatibility complex (mhc) diversity in this species and to elucidate large-scale patterns of genetic partitioning, we examined mhc genetic variability within and among 13 localities, including a disjunct population in arizona and a population from costa rica that may represent an undescribed species. we also tested the hypothesis that ...	2001	11555238
