This study evaluated the suitability of nasal swab for the detection of porcine respiratory disease complex (PRDC) in pigs. Serum, nasal swab, and oral fluid were collected and compared the ability for the detection of PRDC etiologies by PCR. Among 15 pigs, PRRSV was detected in nasal swabs from 12 pigs, oral fluids from 11 pigs, and serum from only 3 pigs. Mycoplasma and PCV2 were detected in 5 and 6 of 13 nasal swab samples, respectively. PRRSV positive signals were found in nasal associated lymphoid tissues (NALT) by ISH. Both viruses and bacteria can be detected in nasal swab samples. Nasal swab could be useful specimen for the detection of PRDC as not only virus but also bacteria could be detected in nasal swab.
