Presence of Merkel cell polyomavirus (MCPyV), human polyomavirus 6 (HPyV6), human polyomavirus 7 (HPyV7) and trichodysplasia spinulosa-associated polyomavirus (TSPyV) was detected by real-time PCR, and presence of HR-HPV DNA by Hybrid Capture 2 assay with subsequent HPV genotyping using the INNO-LiPA HPV Genotyping Extra assay. Cervical biopsies were analysed by histopathology.Results The detection rates were 55.3%, 3.2%, 2.1% and 0% for MCPyV, HPyV6, HPyV7 and TSPyV, respectively, with no significant difference by population. The MCPyV viral load ranged from 14 to 210 DNA copies/106 cells (median, 80 DNA copies/106 cells), with no difference between women with and without cervical precancerous lesions. There was no association between detection of human polyomaviruses in cervical specimens and geographical origin/HIV serostatus, HR-HPV coinfection or precancerous cervical lesions.Conclusions These observations argue against a possible role of MCPyV as a cofactor in HPV-induced carcinogenesis. MCPyV and, to a lesser extent, HPyV6 and HPyV7 might belong to the female genital tract microbiota. ER -
