| comparative phylogeography of mesoamerican highland rodents: concerted versus independent response to past climatic fluctuations. | the phylogeography of sumichrast's harvest mouse (reithrodontomys sumichrasti) was examined through maximum-likelihood and parsimony analyses of 1,130 bp of mitochondrial cytochrome b sequence data from 43 individuals. the phylogeography of this middle american highland forest-dwelling species was compared to that previously published for the codistributed aztec deer mouse complex (peromyscus aztecus/peromyscus hylocetes complex) in order to test competing hypotheses of concerted versus independ ... | 2000 | 10805642 |
| serologic evidence of hantavirus infection in sigmodontine rodents in mexico. | antibodies to hantaviruses in two species of sigmodontine rodents (peromyscus maniculatus and reithrodontomys sumichrasti) collected in central mexico are reported. peromyscus maniculatus, a common species throughout much of mexico, is the reservoir of sin nombre virus (snv), the etiologic agent of the great majority of cases of hantavirus pulmonary syndrome (hps) in north america. although the identity of the virus detected in p. maniculatus in mexico could not be determined by these serologic ... | 2001 | 11310896 |
| serosurvey of wild rodents for hantaviruses in panama, 2000-2002. | five hundred fifty-six samples representing 24 species of small mammals (two species of marsupials and 22 rodents) were collected in panama between february 2000 and july 2002. the samples were examined for antibodies to hantaviruses by means of enzyme-linked immunosorbent assay or immunoblot assays. the serologic results indicated that several rodent species might act as hantaviral reservoirs in panama: costa rican pygmy rice rat (oligoryzomys fulvescens costaricensis), four positive of 72 test ... | 2004 | 15137495 |
| genetic diversity of hantaviruses in mexico: identification of three novel hantaviruses from neotominae rodents. | a variety of hantaviruses are harbored by rodents in north and south america, some of which can cause hantavirus pulmonary syndrome. to obtain greater evolutionary insight into hantaviruses in the americas, a total of 211 rodents were captured in the mexican states of guerrero and morelos in 2006. anti-hantavirus antibodies were detected in 27 of 211 serum samples (12.8%) by elisa. the distribution of seropositive rodents was: 17 peromyscus beatae, 1 megadontomys thomasi, 1 neotoma picta, 6 reit ... | 2011 | 22138671 |
| ecology of hantaviruses in mexico: genetic identification of rodent host species and spillover infection. | in our recent epidemiological survey conducted in mexico for hantavirus infection, we identified three distinct viruses circulating in mexican wild rodents, namely montano virus (mtnv), huitzilac virus (huiv), and carrizal virus (carv). to gain a detailed understanding of hantavirus epidemiology and its associated hosts, 410 rodents were captured at eight collecting points in morelos and guerrero, mexico, and examined for hantavirus seroprevalence, the presence of viral rna, and rodent host spec ... | 2012 | 22750131 |
| molecular phylogenetics and phylogeographic structure of sumichrast's harvest mouse (reithrodontomys sumichrasti: cricetidae) based on mitochondrial and nuclear dna sequences. | sumichrast's harvest mouse (reithrodontomys sumichrasti) is a montane rodent species widely distributed through the mesoamerican highlands. we used sequence data from one mitochondrial (cytochrome b) and two nuclear (β-fibrinogen and acid phosphatase type v) genes for a total of 1962 base pairs to estimate genealogical relationships and assess population genetic structure across the range of this taxon. maximum likelihood and bayesian approaches using cytochrome b resolved several major clades, ... | 2013 | 23578598 |
