Molecular genetic diagnosis of porcine reproductive and respiratory syndrome
Abstract
In the reproductive pathology of pigs, the porcine reproductive and respiratory syndrome virus (RRSS) plays a special role. For the rapid, highly sensitive and specific detection of the viral genome, molecular biological methods, primarily polymerase chain reaction (PCR), have become widespread. Modern developments are aimed at creating diagnostic test systems that allow high efficiency to identify the pathogen genome in the sample, which significantly reduces the time and cost of testing. The developed method makes it possible to identify the RRSS virus genome in various biological material (blood serum, parenchymal organs, virus isolates) with high sensitivity. The study of the above infection showed its widespread distribution in the pathology of pigs.
Thus, the seropositivity of pigs to the PRRS virus on individual pig farms is 77,5 %.
