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(More)
To investigate the genetic diversity of porcine reproductive and respiratory syndrome virus (PRRSV) in Thailand, 279 ORF5 sequences of PRRSV collected during 2010–2011 from 102 swine herds in five swine-producing areas were analyzed. The co-existence of European (EU) and North American (NA) genotypes was observed in 98 % of herds investigated and was(More)
The objective of this study was to investigate the dynamics and evolution of porcine reproductive and respiratory syndrome virus (PRRSV) ORF5 following the use of a modified live PRRSV (MLV) vaccine. A PRRSV-positive farm with coexistence of types 1 and 2 and no history of MLV vaccination was investigated. Vaccination with a type 2 MLV (Ingelvac PRRS MLV,(More)
