Rapid detection of herpes simplex virus by polymerase chain reaction.
This study reports the successful use of three sets of primers, each from different genes on the herpes simplex virus (HSV) genome, 1) the DNA polymerase gene, 2) the glycoprotein B gene, and 3) the glycoprotein D gene, for detection of HSV DNA by polymerase chain reaction (PCR). All three sets of primers detected the same HSV DNA in the throat and genital specimens. Using the conventional viral culture as a standard, PCR provided a sensitivity of 100% and a specificity of 100% in this study. In addition, a nested-PCR protocol using two sets of primers in the glycoprotein D gene, one set internal to the other, was evaluated for the amplification of HSV DNA in cerebrospinal fluid (CSF) from patients suspected of having herpes simplex encephalitis (HSE). Five of the 10 CSF specimens tested were found positive. In conclusion, PCR detection is a valuable tool for rapid diagnosis of HSV infection, especially for CSF specimens.
