| 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 |
| 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. | 1998 | 9452404 |
| geographical distribution of rodent-associated hantaviruses in texas. | the purpose of this study was to increase our knowledge of the geographic distribution and natural host range of hantaviruses in texas, southeastern new mexico, and mexico. blood samples from 3,225 wild rodents, representing 34 species, were tested for hantavirus antibody (igg), using an enzyme-linked immunosorbent assay. hantavirus antibody was found in one or more rodents from each of 13 counties in texas, otero county in southeastern new mexico, and mexico state (central mexico). the 133 anti ... | 2001 | 11469186 |
| 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 ... | 2007 | 17294924 |
| 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 ... | 2013 | 23733291 |
| a review of gongylonema spp. (nematoda: gongylonematidae) in north american rodents with description of a new species from the cotton rat, sigmodon hispidus (mammalia: cricetidae). | gongylonema archboldi n. sp. (nematoda: gongylonematidae) is described from tunnels in the gastric mucosa of the stomach of the cotton rat (sigmodon hispidus) from highlands county, florida, u.s.a. measurements are also given for specimens from cotton mice (peromyscus gossypinus), oldfield mice (peromyscus polionotus), florida mice (podomys floridanus), and golden mice (ochrotomys nuttalli) from the same locality. additional specimens were collected from the cotton rat and the rice rat (oryzomys ... | 2016 | 27394819 |
