Abstract
Polymerase chain reaction (PCR)-based methods for herpes simplex virus (HSV) types I/II genotyping are described. These methods are based on the single-stranded conformation properties of DNA molecules obtained by PCR (PCR-SSCP) and restriction fragment analysis of PCR products (PCR-RFLP). With the aim to analyse these two genotyping techniques, genomic DNA from the standard viral strains KOS and G, and also 79 normal cervical samples were studied for HSV I/II. Sequence analysis showed 19 different RFLP possible systems for HSV typing. Five systems were used in this study and all led to the expected fragments obtained by sequence analysis. PCR-SSCP showed distinct patterns for both viral types and had 100% of concordance with PCR-RFLP results. The prevalence of herpes simplex virus in the normal cervical samples were 21.5% (17 out of 79), the most frequent viral type was HSV-2, with a prevalence of 71% (12 out of 17). Both techniques appeared suitable for HSV I/II genotyping and are easy to perform in most clinical laboratories.
