FIELD: biotechnology.
SUBSTANCE: described is porcine reproductive and respiratory syndrome virus (PRRSV)-CON nucleic acid for eliciting an immune response to PRRSV in pigs, having at least 97 % sequence identity with SEQ ID NO: 1. Also disclosed is a viral particle containing said nucleic acid PRRSV-CON. Also described is a composition containing said nucleic acid or viral particle and a pharmaceutically acceptable carrier. Disclosed is a method for triggering an immune response to PRRSV in pigs, comprising administering to a pig an effective amount of said nucleic acid, an effective amount of said virus particle; or effective amount of composition.
EFFECT: invention extends the range of agents for treating swine reproductive and respiratory syndrome.
