Horizontal gene transfer in the human gastrointestinal tract: potential spread of antibiotic resistance genes
Bacterial infections are becoming increasingly difficult to treat due to widespread antibiotic resistance among pathogens. This review aims to give an overview of the major horizontal transfer mechanisms and their evolution and then demonstrate the human lower gastrointestinal tract as an environment in which horizontal gene transfer of resistance determinants occurs. Finally, implications for ...
متن کاملInter-species population dynamics enhance microbial horizontal gene transfer and spread of antibiotic resistance
Horizontal gene transfer (HGT) plays a major role in the spread of antibiotic resistance. Of particular concern are Acinetobacter baumannii bacteria, which recently emerged as global pathogens, with nosocomial mortality rates reaching 19-54% (Centers for Disease Control and Prevention, 2013; Joly Guillou, 2005; Talbot et al., 2006). Acinetobacter gains antibiotic resistance remarkably rapidly (...
متن کاملHorizontal Gene Transfer as a Global Mediator of Antimicrobial Resistance
Antimicrobial resistance in pathogenic bacteria has become a serious public health concern as infections with multi-drug resistant bacteria are becoming increasingly difficult to treat. In a recent publication by Hatosy and Martiny, the diversity of antimicrobial resistance genes in marine systems was explored using functional metagenomics. Work from these authors, as well as other studies of a...
متن کاملHorizontal Gene Transfer
Horizontal gene transfer (HGT) is the movement of genetic information between organisms, a process that includes the spread of antibiotic resistance genes among bacteria (except for those from parent to offspring), fueling pathogen evolution. Many resistance genes evolved long ago in natural environments with no anthropogenic influence but these genes are now rapidly spreading to and among huma...
متن کاملInferring Horizontal Gene Transfer
Horizontal or Lateral Gene Transfer (HGT or LGT) is the transmission of portions of genomic DNA between organisms through a process decoupled from vertical inheritance. In the presence of HGT events, different fragments of the genome are the result of different evolutionary histories. This can therefore complicate the investigations of evolutionary relatedness of lineages and species. Also, as ...
