We investigated the influences of various reaction conditions on equine herpesvirus type 1 (EHV-1) disinfection by 5 commercial disinfectants (3 quaternary ammonium compounds [QACs] and 2 chlorine-based disinfectants) and 1 anionic surfactant. QACs at their highest recommended concentrations had no virucidal effect on EHV-1 with a 10-min reaction time at 0degC or a 1-min reaction time at room temperature. Chlorine-based disinfectants achieved EHV-1 disinfection with a 10-min reaction time at -10degC or a 30-sec reaction time at room temperature. In the presence of 5% fetal bovine serum, QACs (except for benzalkonium chloride) showed more stable virucidal effects than did chlorine-based disinfectants. The virucidal effect of the anionic surfactant was almost equivalent to that of the QACs.
