Introduction of a PRRSV-1 strain of increased virulence in a pig production structure in Spain: virus evolution and impact on production

2022-11-29

Abstract excerpt

<title>Abstract</title><p>Background A strain<italic>of Porcine reproductive and respiratory syndrome virus</italic>(PRRSV), showing characteristics of enhanced virulence, affected a pyramidal production system from Spain with 7,600 sows in 4 genetic nuclei and 13,000 sows in multipliers. Different PRRSV strains circulating in this production system from December 2020 to October 2021 were detected and sequenced. T...
