PG - 172-5 LID - 10.1016/j.tvjl.2008.11.016 [doi] AB - A multiplex polymerase chain reaction (PCR) was designed for the simultaneous detection of four viruses involved in reproductive and respiratory failure in pigs: porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), classical swine fever virus (CSFV) and porcine reproductive and respiratory syndrome virus (PRRSV). Each of the four pairs of oligonucleotide 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 2.58x10(7), 2.64x10(5), 2.66x10(7) and 2.73x10(5) copies for PRRSV, PCV-2, CSFV and PPV, respectively. Using the multiplex PCR, co-infections with these four viruses were identified in 26/76 (34.2%) piglets born from sows with reproductive failure in China. This method is a rapid, sensitive and cost-effective diagnostic tool for the routine surveillance of viral infections in pigs. CI - Copyright (c) 2008 Elsevier Ltd. All rights reserved.
