Investigating the Presence and Genetic Variability of Porcine Circovirus Types 2 and 3 in Live Markets in Border Cities of Northeast China.

ABSTRACT: Bordering cities and farms serve as potential hotspots for the transboundary spread of animal infectious agents. This study aimed to investigate the presence and genetic variability of porcine circovirus types 2 (PCV2) and 3 (PCV3) in live markets across six border cities (Dandong, Ji'an, Hunchun, Mishan, Fuyuan, and Heihe) in northeast China. Samples from pork (n = 44), cutting boards (n = 46), and meat stall floors (n = 42) were collected in 46 meat stalls. Quantitative PCR analysis detected PCV2 in 75.0% (95% CI: 59.7%-86.8%) of pork samples, 73.9% (95% CI: 58.9%-85.7%) of cutting board swabs, and 64.3% (95% CI: 48.0%-78.4%) of meat stall floor swabs. For PCV3, the detection rates in pork, cutting board swabs, and meat stall floor swabs were 31.8% (95% CI: 18.6%-47.
