Detección de resistencia antimicrobiana en bacterias de interés clínico aisladas en el Río Chambo. Noviembre 2018- enero 2019

Currently antibiotic-resistant bacteria have become a global problem and continue to grow due to the evolution of these microorganisms and the slow pace that is discovering new antibiotics. The objective of this study was to determine the antimicrobial resistance of bacteria of clinical interest isolated from the Chambo River, which allowed the identification of bacteria harmful to human health and difficult to treat with antibiotics. The study is descriptive, cross-sectional with a field design. It began with the collection of samples in six different points taking into account factors such as water temperature, environment and pH. For the isolation and identification of microorganisms, culture media were used: CLED agar, Blood, McConkey and interpretation of physiological and biochemical tests to classify them according to their species. For the measurement of susceptibility or antimicrobial resistance, the Kirby Bauer technique was used. Isolation and identification evince eleven gram-negative pathogenic bacteria: Enterobacteria (81.8%) among these Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Enterobacter aerogenes, Citrobacter freundii and Pseudomonas (18.2%) among these Pseudomonas sp. The majority of the bacteria were resistant to the quinolones and in lesser proportion to the cephalosporins, concluding that the Chambo River is contaminated with bacteria of clinical interest resistant to commonly used antibiotics.
