| fatal illness associated with a new hantavirus in louisiana. | a fatal case of hantaviral illness occurred in louisiana, outside of the range of p. maniculatus, the rodent reservoir for sin nombre virus. hantavirus rna and antigens were detected in patient autopsy tissues, and nucleotide sequence analysis of amplified polymerase chain reaction (pcr) products identified a newly recognized unique hantavirus, provisionally named bayou virus. prominent features of the clinical illness are compatible with hantavirus pulmonary syndrome (hps), but several features ... | 1995 | 7561804 |

| a newly recognized virus associated with a fatal case of hantavirus pulmonary syndrome in louisiana. | genetic analysis of virus detected in autopsy tissues of a fatal hantavirus pulmonary syndrome-like case in louisiana revealed the presence of a previously unrecognized hantavirus. nucleotide sequence analysis of pcr fragments of the complete s and m segments of the virus amplified from rna extracted from the tissues showed the virus to be novel, differing from the closest related hantavirus, sin nombre virus, by approximately 30%. both genome segments were unique, and there was no evidence of g ... | 1995 | 7853545 |

| hantavirus pulmonary syndrome, renal insufficiency, and myositis associated with infection by bayou hantavirus. | hantaviruses are etiologic agents of hemorrhagic fever with renal syndrome, an acute illness characterized by acute renal insufficiency, proteinuria, and hemodynamic instability. recently, a new world form of hantavirus disease, hantavirus pulmonary syndrome (hps), was recognized; in this form, pulmonary edema is prominent, but renal insufficiency is generally lacking. hps cases from the southeastern united states may be exceptional in that they have exhibited both pulmonary and renal manifestat ... | 1996 | 8879771 |
| 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 ... | 1996 | 9025697 |

| 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. | 1997 | 9347961 |

| 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 |
