Multiplex PCR for identification of herpes virus infections in adolescents.

The aim of the study was to develop a multiplex PCR (mPCR) for a rapid and simultaneous detection of herpes simplex 1 (HSV-1), herpes simplex 2 (HSV-2), and human cytomegalovirus (HCMV) DNA in squamous oral cells obtained from adolescents. Accuracy of the method was tested in a group of 513 adolescents, almost 11% of subjects were positive for infection with herpes viruses. Correlations with gender, age, and place of residence were sought. A similar incidence of HSV-2 and HCMV was found (4.3% and 5.4%, respectively) and the incidence of HSV-1 was the lowest (1%) in the study group. Conversely to HSV-2, HCMV was detected mostly in the youngest individuals. The same occurrence of all viruses was observed in boys and girls. The mPCR method described is suggested as a useful tool for epidemiologic studies of active herpes infections. 2010 Wiley-Liss, Inc.
