The immunological-and-biological properties of viral isolates of the porcine reproductive and respiratory syndrome


, : The immunological-and-biological properties of viral isolates of the porcine reproductive and respiratory syndrome. Voprosy Virusologii 49(2): 42-46, March

Described in the paper are study results of some immunobiological properties of 5 field isolates of the porcine reproductive and respiratory syndrome virus (PRRSV), obtained in Russia and Byelorussia in 1998-2001. According to the research work, the PRRSV isolates with different immunobiological properties have been circulating in the territories of Russia and Byelorussia. Three of the 4 examined virus isolates were found to be pathogenic and 1 avirulent to pigs.
