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
small mammal survival and trapability in mark-recapture monitoring programs for hantavirus.following the 1993 hantavirus pulmonary syndrome (hps) epidemic in the south-western united states, mammalogists and epidemiologists instituted long-term studies to monitor population density and prevalence of infection in rodents which constitute the reservoir for sin nombre virus (snv). in this study, field techniques used in sampling small mammals for snv infection were evaluated to determine if trapping and handling protocols were having significant effects on future trapability or mortality ...19989476220
a survey of hantavirus antibody in small-mammal populations in selected united states national parks.hantavirus activity in 39 national parks in the eastern and central united states was surveyed by testing 1,815 small mammals of 38 species for antibody reactive to sin nombre virus. antibody-positive rodents were found throughout the area sampled, and in most biotic communities. antibody was detected in 7% of 647 deer mice (peromyscus maniculatus), 2% of 590 white-footed mice (p. leucopus), 17% of 12 rice rats (oryzomys palustris), 3% of 31 cotton rats (sigmodon hispidus), and 33% of 18 western ...19989574803
hantavirus (bunyaviridae) infections in rodents from orange and san diego counties, california.during a screening program to determine the extent of hantavirus activity in orange and san diego counties, california, serum samples from 2,365 rodents representing nine genera and 15 species were tested for hantavirus antibodies. a reverse transcription-polymerase chain reaction on selected seropositive rodents was used to identify the specific hantavirus. rodents positive for sin nombre virus (snv) antibodies by western blot included 86 (9.1%) of 948 deer mice (peromyscus maniculatus), four ( ...19999988327
do unusual site-specific population dynamics of rodent reservoirs provide clues to the natural history of hantaviruses?between january 1995 and november 1997, longitudinal mark-recapture studies of rodent hosts of hantaviruses in a disturbed microhabitat within a shortgrass prairie ecosystem in southeastern colorado (usa) were conducted. the site was distinguished by edaphic and floristic characteristics unique to this area and associated with historical land use patterns, as well as the year-around availability of water from a functioning windmill. populations of two common rodent species that are hosts for han ...200111310878
genetic identification and characterization of limestone canyon virus, a unique peromyscus-borne hantavirus.hantaviruses, family bunyaviridae, are rodent-borne rna viruses that can cause hantavirus pulmonary syndrome (hps) in various regions of the americas. a coevolutionary relationship exists between hantaviruses and their specific rodent reservoir hosts; the phylogeny of the viruses generally matches that of the rodents. there are several peromyscus-borne hantaviruses, including sin nombre virus, the most common cause of hps in north america. this report describes the genetic detection and characte ...200111485402
epizootiology of sin nombre and el moro canyon hantaviruses, southeastern colorado, 1995-2000.sin nombre virus (snv) is an etiologic agent of hantavirus pulmonary syndrome. to better understand the natural history of this virus we studied population dynamics and temporal pattern of infection of its rodent hosts in southeastern colorado (usa) from 1995 to 2000. we present evidence for the presence of two hantaviruses, snv in deer mice (peromyscus maniculatus) and el moro canyon virus in western harvest mice (reithrodontomys megalotis), at our study sites. sin nombre virus appeared only sp ...200515827206
