Abstract
PENALOZA PINA, Lucía Maribel and ASPIAZU HINOSTROZA, Karla Alexandra. Mechanisms in Escherichia Coli in Ecuador and Latin America. Vive Rev. Salud [online]. 2021, vol.4, n.11, pp.90-103. ISSN 2664-3243. https://doi.org/10.33996/revistavive.v4i11.88.
Bacterial resistance is a natural process of evolution of microorganisms and that can be accelerated by stimulations of the environment that forces pathogens to adapt for their survival. It has become a major problem on a global scale, due to the fact that a considerable number of bacteria of medical importance have acquired resistance to antibiotics and among this group, Escherichia coli stands out, declared by the WHO as a control pathogen, for being the cause of hospital and community diseases and its high multidrug resistance.
Objective.
To determine which are the main resistance mechanisms expressed by E. coli in Latin America.
Method.
A systematic review of the scientific evidence was carried out with the articles published from January 2000 to 2020. The information search was collected from the PubMed, Scopus, Scielo, Science Direct databases.
Results.
430 relevant elements were identified for analysis, after which a total of 18 relevant articles were included for the review.
Conclusion.
The resistance mechanism of Escherichia coli reported to beta-lactams is the production of ESBL, among which those of the CTX-M type stand out. Among the genes resistant to quinolones, the aac (6 ′) Ib-cr gene of plasmid localization stands out, these are generally distributed in Latin America.
Keywords : Escherichia coli; Drug Resistance; Bacterial; Latin America.
