We have evaluated the physical state and infectious nature of Kaposi's
sarcoma-associated herpesvirus (KSHV) in the saliva of nine persons with
past or current Kaposi's sarcoma (KS). KSHV DNA in saliva had the physical
characteristics of DNA present in virions. Inoculation of 293 cells with
cell-free saliva fluid resulted in the persistence of KSHV DNA in culture
for at least 13 passages of the cells. The addition of tetradecanoyl
phorbol acetate to KSHV-infected 293 cells led to increased viral DNA. Two
virus-specific RNAs were detected by reverse transcriptase PCR in 293 cells
infected with cell-free saliva fluid and in cells present in saliva from
subjects with KSHV salivary shedding. These results indicate that
infectious KSHV can be present in saliva of patients with KS.
