Article Synopsis
  • The porcine circovirus type 3 (PCV3) has been identified as a significant pathogen affecting pigs since its discovery in 2016, leading to major economic losses in the swine industry.
  • A study examined 269 mosquito samples from pig farms in China, revealing that 32.0% tested positive for PCV3, suggesting that mosquitoes could play a role in transmitting the virus.
  • Genome sequencing of PCV3 from mosquitoes and pigs showed a 100% similarity, with the virus categorized into two clades (PCV3a and PCV3b), further supporting the idea that mosquitoes may contribute to the virus's transmission cycle.

Background: First identified in the United States in 2016, porcine circovirus type 3 (PCV3) is a newly emerging porcine circovirus exhibiting a wide range of clinical syndromes, which may be associated with the pathogenicity observed in pigs.

Results: The aim of this study was to identify and characterize the full genome sequence of PCV3 strains circulating in Northeast China. Herein, 105 lung samples isolated from sick pigs in Northeast China during 2018 were analyzed for PCV3.
