Persistence of PRRSV and PCV2 in Bacterial Biofilms

13 May 2015

This pilot project from Canada indicates that porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) can survive for several days in bacterial biofilms.

The aim of this pilot project, reported by Dr Carl Gagnon of the University of Montreal in Canada and co-authors there and Laval University was to investigate association of viruses with bacterial biofilms.

Their preliminary data, reported in the Journal of Swine Health and Production, indicate that important viral pathogens of swine, namely, PRRSV and PCV2, can associate with and persist within Gram-positive and Gram-negative bacterial biofilms for several days.

Under the conditions of this study, the efficacy of acid peroxygen and quaternery ammonium-glutaraldehyde commercial disinfectants against PCV2 may be only slightly reduced by the presence of the biofilm.
