Frequent isolation of human herpesvirus 7 from saliva.
We obtained isolates of human herpesvirus 7 (HHV-7) from 6 of 8 healthy adults by culturing saliva with human umbilical cord blood lymphocytes. These isolates were identified as HHV-7 on the basis of comparisons of restriction endonuclease fragment profiles and hybridization with HHV-7 strain RK DNA. The isolates could be differentiated from HHV-7 strain RK and from each other by their restriction endonuclease fragment profiles. We confirm the finding of frequent isolation of HHV-7 from saliva of healthy adults and report the first dual isolation of human herpesvirus 6 (HHV-6) and HHV-7 from a single saliva specimen. We also describe an in situ hybridization assay that can distinguish between HHV-6 and HHV-7.
