Complete Genome Sequence of an NADC30-Like Strain of Porcine Reproductive and Respiratory Syndrome Virus in China
نویسندگان
چکیده
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.

Complete Genome Sequence of a Mosaic NADC30-Like Porcine Reproductive and Respiratory Syndrome Virus in China
Here, we report the complete genome of an NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) strain, HNhx, which was isolated from Henan Province, China, in 2016 and was characterized by recombination with JXA1 strain (an epidemic highly pathogenic PRRSV strain in China) in Nsp4 to Nsp9.
متن کاملComplete Genome Sequence of a Recombinant NADC30-Like Strain, SCnj16, of Porcine Reproductive and Respiratory Syndrome Virus in Southwestern China
The NADC30-like strains of porcine reproductive and respiratory syndrome virus (PRRSV) are characterized by a 131-amino-acid deletion in nonstructural protein 2 (NSP2). Here, we report the complete genome sequence of a recombinant NADC30-like PRRSV strain, SCnj16, that exhibits the molecular marker of the Chinese highly pathogenic PRRSV (HP-PRRSV) in NSP2.
متن کاملNADC30-Like Porcine Reproductive and Respiratory Syndrome in China
NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) has widely spread in China and become locally dominant virus strain in some provinces. Although they are not pathogenic as highly pathogenic PRRSV (HP-RRRSV) that outbreaks since 2006, NADC30-like PRRSVs distinguished themselves by high incidence of recombination with other virus strains which lead to change of virulence. T...
متن کاملGenome characterization of two NADC30-like porcine reproductive and respiratory syndrome viruses in China
BACKGROUND The recent emergence of NADC30-like porcine reproductive and respiratory syndrome virus (PRRSV) in vaccinated pigs arose more attentions for the high incidents of mutation and recombination of PRRSVs. FINDINGS In this study, we determined full-length genome sequences of two NADC30-like PRRSV isolates from recent PRRSV outbreaks in China. Phylogenetic analysis showed that these two ...
متن کاملAnalysis of Genetic Variation of Two NADC30-like Strains of Porcine Reproductive and Respiratory Syndrome Virus in China
BACKGROUND NADC30-like strains of porcine reproductive and respiratory syndrome virus first appeared in Chinese swine herds in 2012. OBJECTIVE AND METHOD To explore the possible genetic diversity of these strains, we sequenced and analyzed the complete genomes of two NADC30-like strains. These isolates shared 95.4% homology with NADC30. RESULT The two strains displayed a discontinuous delet...
