| hantavirus pulmonary syndrome: at the crossroads. | the initial identification in 1993 of hantavirus pulmonary syndrome as a novel, highly fatal respiratory illness among american indians in the southwestern usa in 1993 opened the window to the recognition of a well-established pan-american zoonosis with a myriad of causative viruses and rodent vectors, although all are new world hantaviruses among new world sigmodontine rodents. the clinical spectrum of symptoms has also been expanded to include asymptomatic infection through to fulminant hemorr ... | 2001 | 11979134 |
| emerging infectious diseases in wildlife. | the processes which give rise to emerging infectious diseases of wildlife can be categorised as follows: ecosystem alterations of anthropogenic or natural origin; movement of pathogens or vectors, via human or natural agency; and changes in microbes or in the recognition of emerging pathogens due to advances in the techniques of epidemiology. these are simplistic divisions because factors influencing the emergence of diseases of wild animals generally fall into more than one category. mycoplasmo ... | 2002 | 11974625 |
| andes virus and first case report of bermejo virus causing fatal pulmonary syndrome. | two suspected hantavirus pulmonary syndrome (hps) cases from bolivia occurred in may and july 2000 and were confirmed by enzyme-linked immunosorbent assay (elisa)-andes using n-andes recombinant antigen serology. clot rnas from the two patients were subjected to reverse transcription-polymerase chain reaction (pcr) amplification and sequencing. we describe two characterized cases of hps. one was caused by infection with bermejo virus and the other with andes nort viral lineage, both previously o ... | 2002 | 11971782 |

| hantavirus pulmonary syndrome: the new american hemorrhagic fever. | the recognition of hantavirus pulmonary syndrome (hps) after the investigation of a cluster of unexplained respiratory deaths in the southwestern united states during the spring of 1993 showcased our ability to recognize new and emerging diseases, given the correct juxtaposition of a new clinical entity with circumscribed epidemiologic features that are analyzed with novel diagnostic methods. in less than a decade, hps has become established as a pan-american zoonosis due to numerous viruses mai ... | 2002 | 11941549 |
| acute disseminated encephalomyelitis following nephropathia epidemica. | acute disseminated encephalomyelitis (adem) is an acute monophasic inflammatory and demyelinating disease of the central nervous system (cns) occurring days to weeks after a virus infection or vaccination. nephropathia epidemica (ne) is a haemorrhagic fever with renal syndrome caused by puumala virus, with endemic regions in europe, especially scandinavia and western russia. we describe a case of severe nephropathia epidemica requiring dialysis, followed by severe cns symptoms caused by adem. to ... | 2002 | 11939950 |
| establishment of a deer mouse (peromyscus maniculatus rufinus) breeding colony from wild-caught founders: comparison of reproductive performance of wild-caught and laboratory-reared pairs. | the deer mouse (peromyscus maniculatus) is a natural reservoir for several human pathogens, but little is known about the mechanisms by which such pathogens are maintained in nature. as a first step toward developing a colony of deer mice that were permissive for infection with sin nombre (sn) hantavirus, we collected 68 wild p. maniculatus rufinus from central new mexico. mice from this cohort were used to establish 26 breeding pairs, of which 85% were fertile. in subsequent generations, fertil ... | 2001 | 11924788 |
| mechanisms of integrin-mediated virus attachment and internalization process. | viruses that propagate within vertebrate hosts have adapted many strategies to infect host cells. one of the first steps in a viral infection is the binding of the virus to cell surface molecules. this interaction between a virus and its receptors plays a key role in the multiplication cycle. entry of viruses into cells is a complex, multistep process, and for several viruses, cell attachment and internalization are distinct steps. a number of virus receptors have been identified; a common famil ... | 2001 | 11922076 |
| identification of a cell surface 30 kda protein as a candidate receptor for hantaan virus. | cellular receptors play an important role in virus pathogenesis. as a first step in virus infection, viruses attach to specific receptors on the surface of cells; hantaan virus infects susceptible cells by attaching to a receptor located on the cell surface. to date, the identity of the hantaan virus host cell receptor remains unknown. to determine the protein on the cell surface to which hantaan virus binds, a virus overlay protein-binding assay was performed with radiolabelled virus. a 30 kda ... | 2002 | 11907325 |
| hantavirus nucleocapsid protein interacts with the fas-mediated apoptosis enhancer daxx. | hantaviruses cause two severe diseases, haemorrhagic fever with renal syndrome in eurasia and hantavirus pulmonary syndrome in the americas. to understand more about the molecular mechanisms that lead to these diseases, the associations of puumala virus nucleocapsid protein (puuv-n) with cellular proteins were studied by yeast two-hybrid screening. daxx, known as an apoptosis enhancer, was identified from a hela cdna library and its interaction with puuv-n was confirmed by gst pull-down assay, c ... | 2002 | 11907324 |
| analysis of hantavirus genetic diversity in argentina: s segment-derived phylogeny. | nucleotide sequences were determined for the complete s genome segments of the six distinct hantavirus genotypes from argentina and for two cell culture-isolated andes virus strains from chile. phylogenetic analysis indicates that, although divergent from each other, all argentinian hantavirus genotypes group together and form a novel phylogenetic clade with the andes virus. the previously characterized south american hantaviruses laguna negra virus and rio mamore virus make up another clade tha ... | 2002 | 11907216 |
| serological divergence of dobrava and saaremaa hantaviruses: evidence for two distinct serotypes. | in order to investigate the serological relationship of dobrava hantavirus (dobv, originating from slovenia) and the dobrava-like saaremaa virus (saav, recently discovered in estonia) we analysed 37 human serum samples, 24 from estonia and 13 from the balkans, by focus reduction neutralization test (frnt). most of the estonian sera (19), including all sera from saaremaa island (12), reacted with higher frnt end-point titres to the local saav; the majority of them (15 and 11, respectively), with ... | 2002 | 11895097 |

| transfection-mediated generation of functionally competent tula hantavirus with recombinant s rna segment. | since the discovery of rna recombination in polioviruses, there has been a general belief that this mechanism operates only in positive-sense rna viruses. recently, studying wild-type tula hantavirus, we observed a mosaic-like structure of the s rna segment that was consistent with generation by recombination between viruses from two genetic lineages. here we show transfection-mediated rescue of tula virus carrying recombinant s rna segment. independent attempts yielded s rna molecules of simila ... | 2002 | 11889055 |
| the rna binding domain of the hantaan virus n protein maps to a central, conserved region. | the nucleocapsid (n) protein of hantaviruses encapsidates both viral genomic and antigenomic rnas, although only the genomic viral rna (vrna) is packaged into virions. to define the domain within the hantaan virus (htnv) n protein that mediates these interactions, 14 n- and c-terminal deletion constructs were cloned into a bacterial expression vector, expressed, and purified to homogeneity. each protein was examined for its ability to bind the htnv s segment vrna with filter binding and gel elec ... | 2002 | 11884555 |
