[Behavior of Orf virus in permissive and nonpermissive systems].
Dogs were immunized i.m. with attenuated poxvirus vaccines (vaccinia virus, Orf-virus) and a bovine herpesvirus-1 (BHV-1) vaccine. After intradermal (i.d.) application of the vaccine viruses a specific delayed type hypersensitivity (DTH) reaction of the skin occurred only with vaccinia virus. The i.d. application of Orf-virus caused a short-term, non-specific inflammatory reaction of the skin, even in dogs not immunized with Orf-virus. Out of 30 sera from Orf-virus immunized beagles (n = 4) only eight were found reactive to Orf-virus in a competition ELISA. Three sera from dogs not Orf-virus immunized but skin-tested with the virus contained low antibody titers. Using indirect immunofluorescence (IIF) in flow cytometry, the existence of Orf-virus antigens was examined on the surface and in the cytoplasm of permissive (BFK and Vero)- and questionable permissive MDCK cells. The canine kidney MDCK cell line was found to be non-permissive for Orf-virus replication; the occurrence of an Orf-(ecthyma contagiosum) like disease in dogs is unlikely.
