Biological and Physical Properties

Allan et al. (1994) demonstrated that PCV1 was stable at pH 3, was stable at 56˚C and at 70˚C for 15 minutes, and was resistant to inactivation after exposure to chloroform. The buoyant density of PCV1 in CsCl has been reported to be 1.37 g per cm3 by Tischer et al. (1974), and it has been reported to be 1.36-1.37 g per ml CsClby Allan et al. (1994). The sedimentation coefficient (S) was determined to be 57S when compared with the sedimentation coefficient of a bovine enterovirus (Allan et al., 1994).

PCV2 is readily isolated from tissue samples that have been stored at -70˚C (Ellis et al., 1998). PCV2 was shown to be resistant to some disinfectants (Nolvasan®, DC&R®, Weladol®, or ethanol) but virus titers were significantly reduced by sodium hydroxide , Virkon® S, and others (Royer et al., 2001).
