| australian bat lyssavirus infection: a second human case, with a long incubation period. | in december 1998, a 37-year-old queensland woman died from a rabies-like illness, 27 months after being bitten by a flying fox (fruit bat). molecular techniques enabled diagnosis of infection with australian bat lyssavirus (abl), the second human case to be recognised and the first to be acquired from a flying fox. it must be assumed that any bat in australia could transmit abl; anyone bitten or scratched by a bat should immediately wash the wounds thoroughly with soap and water and promptly see ... | 2000 | 10914106 |
| [emergence of transmissible disorders, a continuous process--a new type of viral meningoencephalitis]. | in the interval 1994-1999, in australia, malaysia and singapore, epizootic and epidemiological episodes of meningoencephalitis and severe acute respiratory syndromes were reported. highly lethal in horses, swine and humans, the episodes were proved to be caused by the "new" viruses hendra (hev) and nipah (niv). at the same time three "new" viral agents have been isolated: lyssavirus, menanglevirus and tupaia paramyxovirus. the intense contemporary circulation of people, animals and food products ... | 2000 | 12089991 |
| cytoplasmic dynein lc8 interacts with lyssavirus phosphoprotein. | using a yeast two-hybrid human brain cdna library screen, the cytoplasmic dynein light chain (lc8), a 10-kda protein, was found to interact strongly with the phosphoprotein (p) of two lyssaviruses: rabies virus (genotype 1) and mokola virus (genotype 3). the high degree of sequence divergence between these p proteins (only 46% amino acid identity) favors the hypothesis that this interaction is a common property shared by all lyssaviruses. the p protein-dynein lc8 interaction was confirmed by col ... | 2000 | 11024152 |
| [genetic diversity of lyssavirus]. | rabies is a zoonosis of which the archaeological agents belong to the lyssavirus species. seven genotypes are known to exist. the isolates are grouped according to a) their geographical origin, b) historical context, c) type of vector. in parts of the world where several epidemic cycles exist, practical tools have been developed in order to distinguish between them more easily. vaccine strains--all of which have been elaborated from genotype 1--offer little or no protection against the other gen ... | 2000 | 11030054 |
| characterisation of a recently isolated lyssavirus in frugivorous zoo bats. | in july 1997 a lyssavirus was isolated in denmark from a colony of egyptian flying foxes (rousettus aegyptiacus) originating from a dutch zoo. sequencing of a 400 nucleotides coding region of the nucleoprotein and of a major part of the g-protein ectodomain encoding region of the newly isolated virus, revealed a very high similarity with european bat lyssavirus subtype 1a (ebl-1a). for characterisation of the recently isolated lyssavirus in frugivorous zoo bats, 16 frugivorous bats (rousettus ae ... | 2000 | 11043951 |
| first isolation of a rabies-related virus from a daubenton's bat in the united kingdom. | on may 30, 1996, a sick daubenton's bat (myotis daubentonii) was recovered from the cellar of a public house in newhaven, east sussex. its condition deteriorated rapidly, and it was euthanased and examined. positive results, establishing the presence of a rabies or rabies-related virus in its brain, were obtained from the fluorescent antibody test, the rabies tissue culture isolation test, and a hemi-nested reverse-transcription pcr. the complete sequence of the nucleoprotein gene was determined ... | 2000 | 11073000 |
| bat lyssavirus infections. | bats, which represent approximately 24% of all known mammalian species, frequently act as vectors of lyssaviruses. in particular, insectivorous bats play an important role in the epidemiology of rabies and some rabies-like viruses, while the haematophagous vampire bats are the major wildlife vector for rabies in latin america. in contrast, the role of fruit bats (flying foxes) in the epidemiology of the recently discovered australian bat lyssavirus is only just emerging. information on the patho ... | 2000 | 11189715 |
