Mutations occur as the consequence of this damage, but may also be caused by improper DNA repair of alterations occurring during normal DNA replication and transcription. Genetic damage can occur at the level of the gene (e.g. point mutations, insertions, and deletions) or at the level of the chromosome (e.g. aneuploidy, translocations). Further, mutations can also take place in mitochondrial DNA. Another form of DNA modification is epigenetic methylation of CpG islands, which affects the dynamics of chromatin as well as the expression of a large panel of genes. Recent technical advances have improved the capacity to detect and quantify genetic and epigenetic changes. This chapter summarizes current knowledge on mechanisms of DNA damage and mutagenesis, laying out the concepts for interpreting mutations as biomarkers in investigating the causes and consequences of cancer. It also outlines both established and novel methods for detecting genetic and epigenetic changes in normal and diseased tissues, and then discusses their application in the realm of molecular epidemiology.</p>","PeriodicalId":13149,"journal":{"name":"IARC scientific publications","volume":" 163","pages":"63-97"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30921801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infectious agents. 传染性病原体。

François Coutlée, Eduardo L Franco
{"title":"Infectious agents.","authors":"François Coutlée,&nbsp;Eduardo L Franco","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The detection and characterization of microbial agents in biological specimens are essential for the investigation of disease outbreaks, for epidemiologic studies of the clinical course of infections, and for the assessment of the role of infectious agents in chronic diseases. Methodological approaches depend on the infectious agent, the specimens analysed and the target populations. Although the diagnosis of infectious diseases has traditionally relied on direct microscopic examination of samples and on the cultivation of microbial agents in vitro, novel techniques with increased sensitivity and specificity are now being used on samples that can be more easily collected and transported to microbiology laboratories (e.g. dried blood spots on filter paper for nucleic acid analysis). Direct detection techniques include the microscopic examination of specimens with special stains, antigen detection and nucleic acid detection by molecular assays. These assays are highly sensitive and provide rapid results for most agents. Genomic amplification assays greatly increase the sensitivity of nucleic acid-based tests by extensive amplification of specific nucleic acid sequences before detection. Real-time polymerase chain reaction (PCR) permits genomic amplification concurrently with detection of amplified products. Typing infectious agents requires additional investigation employing either serologic techniques to identify unique antigenic epitopes, or molecular techniques. These studies are important for epidemiologic purposes, as well as for the investigation of pathogenesis, disease progression, and to establish causality between a disease and a microbial agent. Much of bacteriology has relied on growth of organisms on artificial media, and on identification of bacterial growth with biochemical, serological, or more recently, nucleic acid-based tests. The detection of specific antibodies from the host directed against pathogens is another strategy to identify current or past infections.</p>","PeriodicalId":13149,"journal":{"name":"IARC scientific publications","volume":" 163","pages":"175-87"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30921806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
