Comparison of diploid fibroblast and rabbit kidney tissue cultures and a diploid fibroblast microtiter plate system for the isolation of herpes simplex virus.

摘要

We evaluated the relative sensitivities of two cell systems (rabbit kidney [RK] and human diploid fibroblast [DF; human embryonic tonsil]) in standard tube cultures versus DF cells in a 48-well microtiter plate system for the detection of both symptomatic and asymptomatic herpes simplex virus (HSV) infection. At least one system isolated HSV in 111 of 809 specimens (13.7%). HSV was isolated in RK tube cultures from 110 specimens (99%), in DF tube cultures from 91 specimens (82%), and in DF microtiter plates from 95 specimens (86%). The frequency of HSV isolation varied with the anatomic site and the presence or absence of a herpetic lesion. The sensitivities of the three culture systems remained similar whether the specimens were obtained from lesions or whether the specimens were taken to determine if asymptomatic excretion of HSV was present. While RK tube cultures were more sensitive than DF tube cultures, the DF microtiter plate system was as sensitive as DF tube cultures and its use is supported as a cheaper and less labor-intensive method for the detection of HSV.
