Abstract
PCV-2 (Porcine circovirus type-2, PCV-2) and PRRSV (Porcine reproductive and respiratory syndrome virus, PRRSV) were detected by PCR from 253 porcine pleuropneumonia samples and 125 clinically healthy lung samples were collected from different districts of Shandong province. The results showed that 171 samples for PCV-2 and 101 samples for PRRSV were positive. The positive ratio were 67.5% and 40%, respectively. The co-infection number of PCV-2 and PRRSV was 68 in 253 samples, the positive ratio was 26.8%. While in the clinically healthy samples, only 21 samples for PCV-2 and 12 samples for PRRSV were detected positive, the positive ratio were 16.8% and 9.6%, respectively, no co-infection samples were found. Statistical result showed significant difference between positive ratio for PCV-2 and PRRSV in porcine pleuropneumonia samples and that of in clinically healthy samples. The above results demonstrated that there maybe some relationship between the infection of porcine pleuropneumonia and PCV-2 and PRRSV in pigs.
