| the complete sequence of a human astrovirus. | we have determined the complete genomic sequence of human astrovirus serotype 1 isolated in newcastle upon tyne. the genome is 6813 nucleotides long and contains three sequential open reading frames (orfs). the two closest to the 5' end are linked by a ribosomal frameshifting motif and contain sequence motifs indicative of non-structural virus proteins: serine protease and rna-dependent rna polymerase. a nuclear addressing sequence is also located here. the 3' orf encodes the virion structural p ... | 1994 | 8021608 |
| prevalence of human astrovirus serotypes in the oxford region 1976-92, with evidence for two new serotypes. | results of serotyping on 291 astrovirus-positive stools collected between 1976 and 1992 showed that about two-thirds (64.9%) were serotype 1. infections were more frequent in the fourth quarter of the year and there was a suggestion that during the past 5 years serotype 1 has occurred with greater frequency in alternate years. evidence is provided for the existence of two new serotypes, 6 and 7. | 1994 | 8119358 |
| seroprevalence of astrovirus types 1 and 6 in london, determined using recombinant virus antigen. | we have developed a microimmunofluorescence test (if) which uses cells infected with a recombinant baculovirus which expresses the capsid proteins of astrovirus types 1 or 6. the if test was sensitive and specific and the results for human astrovirus type 1 (hast-1) were comparable to those obtained by immune electronmicroscopy and radioimmunoassay. application of the test to a panel of 273 sera collected from patients and staff at two childrens hospitals in london showed that over 50% of the po ... | 1996 | 8760964 |
| absence of human astrovirus rna in sewage and environmental samples. | over a period of several weeks during the summer of 1996, samples of sewage, sea water, river water, sand and silt were collected from a sewage works at weston-super-mare, england and from coastal areas nearby. a sensitive reverse-transcriptase polymerase chain reaction (rt-pcr) was used to search for human astrovirus (hastv) rna in concentrates of the samples. no evidence of astrovirus was found in any sample, which suggests that contamination with these viruses is not a problem in this area du ... | 1999 | 10212416 |
