| characterisation of the bovine enteric calici-like virus, newbury agent 1. | the bovine enteric calici-like virus, newbury agent 1 (na1) was characterised to determine if it is a member of the caliciviridae and to establish its antigenic relationship to the established bovine enteric calicivirus newbury agent 2 (na2). solid phase immune electron microscopy (spiem) allowed quantification of na1 virions and identification of faecal samples with optimal virus levels. na1 particles were 36.6 nm in diameter, had an indefinite surface structure resembling that of human small r ... | 2000 | 11040440 |
| genomic characterization of the unclassified bovine enteric virus newbury agent-1 (newbury1) endorses a new genus in the family caliciviridae. | the pathogenic bovine enteric virus, newbury agent-1 (bo//newbury1/1976/uk), first identified in 1976, was characterized as a possible calicivirus by morphology, buoyant density in cscl and the presence of a single capsid protein but genomic sequence could not be obtained. in the present study, the complete genome sequence of newbury1 was determined and classified newbury1 in a new genus of the caliciviridae. the newbury1 genome, of 7454 nucleotides, had two predicted open reading frames (orfs). ... | 2006 | 16574184 |
| molecular detection and characterization of unclassified bovine enteric caliciviruses in south korea. | the unclassified bovine enteric calicivirus (bec) is a new bovine enteric calicivirus that is different from bovine norovirus, and causes diarrhea and pathologies in the small intestine of calves. this virus includes nebraska (nb)- and newbury agent 1 (na1)-like strains. the prevalence of this bec and its genetic characterization has only been reported in the uk and the usa. this study examined the prevalence and genetic diversity of these becs in diarrheic calves in south korea. among a total o ... | 2008 | 18387758 |
