Characterization and comparison of porcine circovirus sequences from postweaning multisystemic wasting syndrome affected and non-affected herds.
Proceedings of the 4th International Symposium on Emerging and Re-emerging Pig Diseases, 2003, 186
A total of 38 tissue samples collected in pigs originating from seven PMWS-diagnosed herds (PMWS(+)) and seven non-PMWS (PMWS(-)) herds were collected. PCV1 and PCV2 DNA was detected, amplified and sequenced. PCV1 was not detected in any of the submitted sample. PCV2 prevalence in PMWS(-) herds was high (83%). The sequencing of PCV2 genomic sequences obtained from the various tissue extracts confirmed a high nucleotide identity. No virulence factor in PMWS(+) strains could be identified.
