Abstract:
A method for the typing of infectious herpesvirus in a specimen comprising the steps of:a) providing:i) a specimen suspected of containing one or more members of the herpesvirus family;ii) a cell line permissive for infection by one or more members of the herpesvirus family;iii) a genetically engineered cell line susceptible to infection by said one or more members of the herpesvirus family, said genetically engineered cell line containing a nucleic acid molecule having a sequence comprising a promoter sequence derived from a member of the herpesvirus family wherein said promoter sequence is operably linked to a reporter gene, the expression of said reporter gene being dependent upon and quantitatively proportional to the presence of said herpesvirus and wherein the expression of said reporter gene varies in a distinguishable manner as a result of the presence of different members of said herpesvirus family;b) mixing together said permissive cell line and said genetically engineered cell line to create a mixed cell culture;c) inoculating said mixed cell culture with said specimen under conditions which permit the infection of said mixed cell culture by said members of the herpesvirus family, wherein said infection results in a distinguishable pattern of expression by said reporter gene;d) detecting the expression of said reporter gene and thereby detecting the presence of said one or more members of the herpesvirus family in said specimen; and(e) identifying the presence of a specific member of said herpesvirus family based upon the resulting distinguishable pattern.
