RESUMEN
INTRODUCTION: Herpesviruses are a widespread family of double-stranded DNA viruses that establish life-long persistent infection in their hosts. Cumulative evidence tends to argue for the association of human herpesviruses, such as Kaposi's sarcoma herpesvirus (KHSV), Epstein-Barr virus (EBV), and human cytomegalovirus (HCMV) with various human disorders and diseases. The present study aims to investigate the presence of herpesviruses in colorectal cancer (CRC). METHODOLOGY: We investigated the presence of herpesviruses in 69 formalin-fixed paraffin embedded tissue (FFPE) biopsies, using a pan-herpesvirus nested polymerase chain reaction (PCR) with degenerate primers and HCMV specific primers to identify the presence of herpesviruses in CRC tissue. RESULTS: None of the samples we examined were positive for herpesviruses. CONCLUSIONS: Our results suggest that there is no (or very low) prevalence of lifelong herpesvirus infection in Algerian CRC patients. Larger cohorts may provide more insight into the prevalence of herpesviruses in Algerian CRC biopsies.
