Previous studies have reported an association between genital dysbiosis and HPV infection in women and also in men co-infected with HPV and HIV. However, it remains to be determined whether penile skin dysbiosis is associated with HPV infection in men who are HIV-negative. This study characterizes the penile skin microbiota (PSM) of HPV-positive and HPV-negative men, hypothesizing that HPV infection is linked to dysbiotic anaerobic-dominated communities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional study was conducted on 103 sexually active HIV-negative men (70 HPV-negative, 33 HPV-positive). Those who tested HPV-positive were genotyped. The PSM of all samples was analyzed using 16S rRNA sequencing of the V4 region. Alpha and beta diversity were compared. Community State Types (CSTs) were identified using hierarchical clustering. Associations between CSTs and HPV status were tested adjusting for sexual preference.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      HPV-positive men exhibited significantly higher microbial richness than HPV-negative men (Chao1\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = .02), particularly those with high-risk genotypes (Chao1\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = .03).
