Research on the presence of porcine enterovirus serotype 1 in north-eastern Italy.

The liquid-phase blocking sandwich ELISA, already developed for foot-and-mouth disease and swine vesicular disease serology, has been employed in pig sera for the antibody detection against porcine enterovirus serotype 1. ELISA-titers correlate positively with virus neutralization and their distribution show a high prevalence among the sampled pigs. The serological findings are confirmed by the isolation of a field strain of porcine enterovirus belonging to the serotype 1.
