Phylogenetic Analysis of Porcine Circovirus 3 Circulating in Canadian Pigs

Jun 24, 2022

Abstract: Phylogenetic analysis of porcine circovirus 3 circulating in Canadian pigs

Introduction: Porcine circovirus 3 (PCV3) has been detected in pigs worldwide and associated with several clinical signs.
Methods: To investigate the genetic diversity of PCV3 strains circulating in Canada, 44 PCV3 positive samples from Saskatchewan (2/44), Manitoba (2/44), Quebec (4/44), Alberta (11/44) and Ontario (25/44) submitted to diagnostic laboratories in Canada between 2019 and 2021 were sequenced and analyzed.
Results: Phylogenetic analysis of capsid genes showed that all of the 44 Canadian strains classified into PCV3a and segregated into seven lineages with common amino acid changes observed at A24V, R27K, N56D, T77S, Q98R, L150I (F) and R168K positions.

Video: Trailer Biosecurity at Harvest Plants - Dr. Lucas Ferreira

In this episode of The Swine Health Blackbelt Podcast, Dr. Lucas Ferreira, a Research Assistant at the University of Minnesota, discusses trailer contamination risks at packing plants. He shares research on pathogen prevalence, seasonal trends, driver biosecurity practices, and factors contributing to contamination during transport. He highlights opportunities to strengthen biosecurity and reduce disease transmission across swine operations. Listen now on all major platforms!

"Trailer washing gaps allow harvest plant contamination to increase pathogen risk before equipment returns to farms or wash facilities."

Meet the guest: Dr. Lucas Ferreira https://www.linkedin.com/in/lucas-fer... is a veterinarian from Brazil currently pursuing a master's degree at the University of Minnesota. His work focuses on swine pathogen epidemiology, detection, control, and prevalence, with an emphasis on science-driven solutions that improve herd health and biosecurity.
