title: Detection of herpes simplex virus type 1 in addition to Epstein-Bar virus in tonsils using a new multiplex polymerase chain reaction assay.
abstract: HSV-1, HSV-2, CMV, EBV, which are the members of the herpes virus family colonize and establish latent infection in human. Although EBV is a well known virus most involved in recurrent bouts of acute tonsillitis, the role and possibility of HSV-1, HSV-2, and CMV for establishing infection in tonsils are not clear. The purpose of this study is to verify whether the tonsils might harbor the HSV-1, HSV-2, and CMV, in addition to EBV, in chronically hyperplastic nasopharyngeal lymphoid tissue. To accomplish the purpose, we developed a new Multiplex Polymerase Chain Reaction (M-PCR) assay using a single consensus forward primer and virus specific reverse primers for DNA polymerase gene of HSV-1, and 2, EBV, and CMV, and investigated its efficiency for detecting HSV1, HSV2, CMV, and EBV. The sample of 52 patients underwent tonsillectomy or adenectomy because of chronic lymphoid hyperplasia without any evidence of acute infections and were investigated for presence of HSV-1, HSV-2, CMV, and EBV. Of the 54 samples, 11 (20.4%) of them were positive for EBV, 4 of them (7.4%) were positive for HSV-1, and none of the samples were positive for HSV-2 and CMV. To the best of our knowledge, this is the first report that tonsils may be the reservoir for HSV-1 in addition to EBV, and HSV-1 may have a role in recurrent tonsillitis and systemic diseases. The MC-PCR assay presented in this study can provide a rapid, sensitive, and economical method for detection of HSV-1, HSV-2, EBV, and CMV in a single PCR tube.
