Genetic signatures of the immune-escaping type 2 porcine reproductive and respiratory syndrome virus in farms with a robust vaccination program.

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important porcine viruses worldwide. Recently, severe PRRS outbreaks had occurred in two farms located in eastern and southern Thailand where stringent vaccination had been routinely practiced. Genetic analysis of GP5 identified two highly virulent PRRSVs designated as NA/TH/S001/2015 and NA/TH/E001/2016 from the southern and eastern farms, respectively.

Tembusu-Related Flavivirus in Ducks, Thailand.

Since 2013, outbreaks of disease caused by duck Tembusu virus (DTMUV) have been observed in layer and broiler duck farms in Thailand. The virus is closely related to Chinese DTMUVs and belongs to the Ntaya group of mosquitoborne flaviviruses. These findings represent the emergence of DTMUV in ducks in Thailand.

Genetic diversity of porcine reproductive and respiratory syndrome virus in Thailand and Southeast Asia from 2008 to 2013.

Porcine reproductive and respiratory syndrome virus (PRRSV) affects the swine industry worldwide. Annual surveillances taken from 2008 to 2013 revealed a 13.86% prevalence of PRRSVs in swine populations in Thailand.
