Abstract

Fecal samples from 27 pigs were longitudinally analyzed for Teschovirus A (TV-A), Sapelovirus A (SV-A), and Enterovirus G (EV-G) RNA presence. Suckling piglet fecal samples were negative for the three enteric picornaviruses. However, these picornaviruses were detected in 22/27 weaned pig fecal samples. This study provides new data on TV-A, SV-A, and EV-G infection dynamics.

Keywords: Fecal shedding; Infection dynamics; Picornaviridae; Porcine enterovirus; Swine.
