We characterized isolates from porcine respiratory and reproductive syndrome virus epidemics in Vietnam and China in 2007. These isolates showed approximately 99% identity at the genomic level. Genetic analysis indicated that they share a discontinuous deletion of 30 aa in nonstructural protein 2, which indicates that identical variants emerged in Vietnam and China.
Two reassortant H16 influenza A viruses were isolated from gulls in California. Seven of the eight segments were most closely related to H16 and H13 isolates from eastern North America and Iceland. Of note is a C-terminal truncation of the nonstructural 1 (NS1) protein in one of the isolates that is usually found in swine H1N1 virus.
The most recently emergent porcine reproductive and respiratory syndrome virus strains in China are characterized by 393 nucleotide deletions in the nonstructural protein 2 (NSP2) region and are known as NADC30-like strains. Here, we report the complete genome sequence of the NADC30-like HNjz15 strain that was isolated in 2015.
In this study, we report the complete genome sequence of the bovine viral diarrhea virus 2 Japanese reference strain KZ-91CP. The complete genome comprises 12,654 nucleotides and one open reading frame with 4,020 amino acids. A 369-nucleotide-long insertion encoding the chaperone protein DnaJ is found in the nonstructural 2 (NS2) coding region.
Characterization of porcine reproductive and respiratory syndrome virus (PRRSV) isolates from pigs in Thailand showed 30-aa discontinuous deletions in nonstructural protein 2, identical to sequences for highly pathogenic PRRSV. The novel virus is genetically related to PRRSV from China and may have spread to Thailand through illegal transport of infectious animals from bordering countries.
Mutations were introduced into plasmid pMM984, a full-length infectious clone of the fibrotropic strain of minute virus of mice, to identify cis-acting genetic elements required for the excision and replication of the viral genome. The replicative capacity of these mutants was measured directly, using an in vivo transient DNA replication assay following transfection of plasmids into murine A9 c...
The species Human enterovirus B (HEV-B) in the family Picornaviridae consists of coxsackievirus A9; coxsackieviruses B1 to B6; echoviruses 1 to 7, 9, 11 to 21, 24 to 27, and 29 to 33; and enteroviruses 69 and 73. We have determined complete genome sequences for the remaining 22 HEV-B serotypes whose sequences were not represented in public databases and analyzed these in conjunction with previo...
