[Role of infectious agents in the emergence of malignant tumors].

[Article in Russian]

Abstract

According to the data of the International Agency for Research on Cancer (IARC), at least 6 virus species (HPV, EBV, HHV-8/KSHV, HTLV-1, HBV, HCV), 4 helminthes species (Schistosoma haematobium and japonicum, Opisthorchis viverrini, Clonorchis sinensis) and I bacterium species (Helicobacter pylori) have been proved to be capable of causing the development of cancer. The analysis of the data available shows that Merkel cell polyomavirus (MCV), herpes simplex virus (HSV), John Cunningham polyomavirus (JCV), monkey virus 40 (SV40), cytomegalovirus (CMV), xenotropic murine leukemia virus (XMRV), Helicobacter bilis and hepaticus, Campylobacter jejuni, Fusobacterium varium, enteropathogenic Escherichia coli, enterotoxigenic Bacteroides fragilis, Bacteroides vulgatus, Prevotella spp., Streptococcus bovis and anginosus, Treponema denticola, Salmonella typhi, paratyphi and typhimurium, Borrelia burgdorferi, Bartonella spp., Mycobacterium tuberculosis, Chlamydia pneumoniae, trachomatis and psittaci, Neisseria gonorrhoeae, Propionibacterium acnes, Tropheryma whippelii, Schistosoma mansoni, Opistorchis felineus, Strongyloides stercoralis, Taenia solium, Candida spp., Paracoccidioides brasiliensis, Histoplasma capsulatum and Trichomonas vaginalis can also be potential etiological agents of cancer. Apparently, detection of new associations between infectious agents and risk of the development of cancer will facilitate progress in elaboration of prophylaxis measures, early diagnostic methods and, probably, methods of treatment of malignant tumors.
