各種消毒薬の木綿包帯, 鶏卵殻および木片に付着したウイルスに対する殺ウイルス効果とその持続について

Abstract

First, 8 disinfectants were tested for virucidal effect on three DNA viruses, bovine herpesvirus-1 (BHV-1), vaccinia virus (VV) and canine adenovirus, and three RNA viruses, Newcastle disease virus (NDV), bovine enterovirus and bovine rotavirus. To the viruses coated on a cotton dressing gauze, all the disinfectants used had a virucidal effect on both enveloped DNA and RNA viruses and the disinfectants on the chlorine and aldehyde groups had the same effect on non-enveloped DNA and RNA viruses. To the viruses coated on a chicken egg-shell, all the disinfectants used had a destructive effect on both enveloped DNA and RNA viruses. To the viruses coated on poplar-wooden shavings, the disinfectants of the chlorine and aldehyde groups had a virucidal effect on some enveloped DNA and RNA viruses, VV and NDV, and the disinfectant of only the aldehyde group had a virucidal effect on all viruses.Secondly, five disinfectants were tested for the durability of their virucidal effects on NDV and fowl adenovirus (FAV) after making their working solutions. The disinfectants of the orthodichloro-benzene-cresol and chlorine groups maintained their virucidal efficiency for 2-4 days on NDV, and the remainings for 2 days. In the presence of chicken feces as organic matter, the virucidal effect of the orthodichloro-benzene-cresol and chlorine groups were not influenced but that of the reverse soap group was strongly influenced and became invalid. Only the chlorine group maintained its virucidal effect on FAV for 2-4 days.
