Sažetak

A multiplex polymerase chain reaction (PCR) was designed for the simultaneous detection of four viruses involved in postweaning multisystemic wasting syndrome (PMWS) in pigs: porcine circovirus type 2 (PCV-2), type 2 porcine reproductive and respiratory syndrome virus (PRRSV), porcine parvovirus (PPV) and pseudorabies virus (PRV). Each of the four pairs of primers exclusively amplified the targeted fragment of the specific viruses. The sensitivity of the multiplex PCR, using purified plasmid constructs containing the specific viral target fragments, was 4.0×103, 4.5×103, 3.0×102 and 5.0×102 copies for PCV-2, type 2 PRRSV, PPV, PRV. Among 82 clinical samples, coinfection by PCV-2 and type 2 PRRSV was the most common. When compared with the virus isolation method commonly used to detect viruses, the multiplex PCR assay was found to be more sensitive and rapid and, as such, may prove to be a good alternative method for the detection of and differentiation in PMWS in pigs.
