Ten of the 31 samples (32%) were positive for HPV DNA and all of the samples were positive for human beta-globin. The genotypes identified were HPV 16 (n=3), HPV 58 (n=2) and HPV 39, 45, 51, 59, 66 and 69 (n=1 for each). The three samples positive for HPV 16 had lost region E2, meaning that the viral DNA had been integrated into the host genome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
