Introduction: Antimicrobial resistance is a serious public health problem that is increasing. Among the most important factors related to the spread of multi-resistant bacteria are the inappropriate use of antibiotics and the insufficient implementation of prevention and control measures. Additionally, bacteria have the ability to mutate or create mechanisms for transfer of resistance genes via plasmids, transposons and integrons. Materials and methods: A critical review of the literature on major resistance genes in Gram negative bacteria and its impact on public health was conducted. Data have been collected from Medline, Embase, Lilacs, ScienceDirect, Scopus, SciELO, the Cochrane Library and Lilacs. Results: A review of literature that describes and analyzes the main antibiotic resistance genes present in gram-negative bacilli is presented, as well as their origin, evolution, and subsequent spread to hundreds of species of microorganisms by Horizontal gene transfer which justifies the importance of conducting an epidemiological surveillance on transit of clones with different resistance profiles and major enzymes. Conclusions: The control of antimicrobial resistance from the point of view of molecular epidemiology is part of the antibiotic surveillance control as recommended by the World Health Organization; as it represents the future of the surveillance of resistance.

Keywords : Bacterial drug resistance; bacterial genes; public health; horizontal gene transfer.
