The Journal of HPV and other Small DNA Tumor Viruses;Volume 5, June 2018, Journal article; Peer reviewed, 2018-04-30)
      Human papillomaviruses (HPVs) co-evolve slowly with the human host and each HPV genotype displays epithelial tropisms. We assessed the evolution of intra HPV genotype variants within samples, and their association to ...
    • Microbial dynamics with CRC progression: a study of the mucosal microbiota at multiple sites in cancers, adenomatous polyps, and healthy controls
