cocirculation of multiple hantaviruses in texas, with characterization of the small (s) genome of a previously undescribed virus of cotton rats (sigmodon hispidus).an environmental and laboratory investigation was conducted after a fatal childhood case of hantavirus pulmonary syndrome occurred in deaf smith county, texas in may 1995. a trapping campaign was conducted to identify possible rodent carriers. six species of murid and heteromyid rodents were collected, and at least one hantavirus-seropositive specimen was found in each of the five murid species. tissues from a selection of 11 seropositive specimens were examined by the polymerase chain reaction ...19969025697
a longitudinal study of bayou virus, hosts, and habitat.what is currently known about the ecology of north american hantaviruses has come largely from studies on sin nombre virus (snv). we conducted a longitudinal study of bayou virus (bayv), the second-leading agent of hantavirus pulmonary syndrome in the united states. antibodies to hantavirus were detected from oryzomys palustris (most commonly infected species), sigmodon hispidus, peromyscus leucopus, reithrodontomys fulvescens, and baiomys taylori. however, only o. palustris had viral rna in tis ...200516354810
bayou virus detected in non-oryzomyine rodent hosts: an assessment of habitat composition, reservoir community structure, and marsh rice rat social dynamics.in the united states, bayou virus (bayv) ranks second only to sin nombre virus (snv) in terms of hantavirus pulmonary syndrome (hps) incidents, having been confirmed in cases from texas and louisiana since its discovery in 1994. this study on bayv infection among sympatric, non-oryzomyine rodents ("spillover") in freeport, tx, is the first to link patterns of hantavirus interspecific spillover with the spatiotemporal ecology of the primary host (marsh rice rat, oryzomys palustris). mark-recaptur ...200920836801
muleshoe virus and other hantaviruses associated with neotomine or sigmodontine rodents in texas.the broad objective of this study was to increase our knowledge of muleshoe virus and other hantaviruses associated with cricetid rodents in texas. anti-hantavirus antibody was found in 38 (3.2%) of 1171 neotomine rodents and 6 (1.8%) of 332 sigmodontine rodents from 10 texas counties; hantaviral rna was detected in 23 (71.9%) of 32 antibody-positive rodents. analyses of nucleocapsid protein gene sequences indicated muleshoe virus infection in four hispid cotton rats (sigmodon hispidus) from nor ...201728714801
