Cervical cancer microbiome analysis: comparing HPV 16 and 18 with other HPV types.

ABSTRACT: Differences in the cervicovaginal microbiome may influence the persistence of HPV and therefore, the progression to cervical cancer. We aimed to analyze and compare the metatranscriptome of cervical cancers positive for HPV 16 and 18 with those positive for other HPV types to understand the microbiome's influence on oncogenicity. RNA sequencing data from a total of 222 invasive cervical cancer cases (HPV16/18 positive (n=42) and HPV "Other types" (n=180)) were subjected to taxonomy classification (Kraken 2) including bacteria, virus and fungi to the level of species. With a median depth of 288,080.5 reads per sample, up to 107 species (38 bacterial, 16 viral and 53 fungal) were identified. Diversity analyses revealed no significant differences in viral or fungal species between HPV16/18 an
