enzootic of bayou hantavirus in rice rats (oryzomys palustris) in 1983. 19957658901
isolation, genetic diversity, and geographic distribution of bayou virus (bunyaviridae: hantavirus).bayou hantavirus, previously implicated in human hantavirus pulmonary syndrome in louisiana, was isolated from a rice rat (oryzomys palustris) captured in georgia. the presence of antibody among rice rats captured throughout the southeastern united states and the extent of diversity among the genetic variants of bayou viruses suggest that the rice rat is the most likely natural reservoir of the virus and that both virus and host have probably co-evolved for some years.19979347961
bayou virus-associated hantavirus pulmonary syndrome in eastern texas: identification of the rice rat, oryzomys palustris, as reservoir host.we describe the third known case of hantavirus pulmonary syndrome (hps) due to bayou virus, from jefferson county, texas. by using molecular epidemiologic methods, we show that rice rats (oryzomys palustris) are frequently infected with bayou virus and that viral rna sequences from hps patients are similar to those from nearby rice rats. bayou virus is associated with o. palustris; this rodent appears to be its predominant reservoir host.19989452404
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
catacamas virus, a hantaviral species naturally associated with oryzomys couesi (coues' oryzomys) in honduras.the primary objective of this study was to extend our knowledge of the geographical distribution, genetic diversity, and natural host associations of the hantaviruses indigenous to north america. antibody to a hantavirus was found in 5 (20.8%) of 24 coues' oryzomys (oryzomys couesi) and none of 41 other rodents captured near the town of catacamas in eastern honduras, and a hantavirus was isolated from one of the antibody-positive coues' oryzomys. analyses of nucleotide and amino acid sequence da ...200617124003
seasonal variation of north american form of gigantolaelaps mattogrossensis (acari: laelapidae) on marsh rice rat in southern coastal texas.the ectoparasites of a small mammal community within an intertidal zone in the upper gulf coast region of texas were studied to assess the seasonal variation in abundances of the mite gigantolaelaps mattogrossensis (fonseca) (acari: laelapidae) on the marsh rice rat, oryzomys palustris (harlan). further study into the ecology and dynamics of this parasite-host relationship was deemed to be necessary to expand the understanding of these potential participants in the ecology of bayou hantavirus, a ...200717294924
bayou virus detected in non-oryzomyine rodent hosts: an assessment of habitat composition, reservoir community structure, and marsh rice rat social 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
socio-ecology of the marsh rice rat (oryzomys palustris) and the spatio-temporal distribution of bayou virus in coastal texas.along the southeastern coast of the united states of america (usa), the marsh rice rat (oryzomys palustris) is the primary host for the hantavirus, genotype bayou. according to the socio-ecological model for a territorial, polygamous species, females should be distributed across space and time by habitat resources and predation risks, whereas males should space themselves according to the degree of female aggregation and reproductive synchrony. to investigate how females affect the male-male tra ...201323733291
