Abstract
A multiplex PCR assay was developed that enabled the simultaneous detection of DNA from 6 types of human herpes virus, HSV-1/2, VZV, EBV, CMV, HHV-6A/B, and HHV-7, using appropriate primer sets and conventional PCR techniques and instruments, with PCR products for each type of virus designed to be easily distinguishable by size. Electropherograms obtained from conventional agarose gels showed that, for each type, the observed number of base pairs corresponded to the intended product and that bands were easily distinguishable from each other. A minimum of 20 copies of viral DNA in a reaction was sufficient to confirm the existence of each of the 6 types of human herpes virus. Comparison of the data obtained from this method and the data obtained from conventional TaqMan PCR using clinical specimens from various sources showed consistent results. The multiplex PCR method reported here for the detection and differentiation of human herpes viruses did not require special equipment or techniques such as hybridization analysis and sequencing analysis and, therefore, enabled us to easily and rapidly detect and identify the 6 types of human herpes virus using conventional methods.
