It is now widely accepted that infection of stomach tissue with the bacteria Helicobacter pylori is an important cause of stomach adenocarcinoma. In addition, oncogenic viruses, such as papilloma viruses, herpes viruses, and hepadnaviruses are strongly associated with increased risk of cervical cancer, lymphomas, liver cancer, amongst others. However, in the scientific community the percentage of cancers caused by pathogens is believed to be far higher than 15%. A significant volume of data collected to date show an association between infectious agents and urogenital cancers. These agents include Chlamydia trachomatis, Neisseria gonorrhoea, Mycoplasma genitalium and certain viruses that have been implicated in ovarian cancer.enAttribution-NonCommercial-ShareAlike 3.0 United Statesurogenital cancersovarian cancercervical cancerBladder cancerKidney cancerChlamydia trachomatisNeisseria gonorrheaMycoplasma genitaliumSchistosoma haematobiumHPVEpstein-BarrCMVHuman polyomavirusesResearch Subject Categories::MEDICINE::Microbiology, immunology, infectious diseasesArticle
