Item Análisis de los mecanismos de resistencia en enterobacterias presentes en aguas residuales urbanas en Latinoamérica: una revisión sistemática de la literatura(Universidad Satiago de Cali, 2025-12-10) Mosquera Arboleda, ValeriaThis monograph addresses the study of Enterobacteriaceae present in urban wastewater in Latin America, with an emphasis on antimicrobial resistance mechanisms and the environmental factors associated with their persistence and spread. The objective was to analyze the available scientific evidence on resistance mechanisms in Enterobacteriaceae detected in wastewater through a systematic literature review based on the PRISMA methodology. The search was conducted in specialized scientific databases, integrating publications in English and Spanish corresponding to the period 2015–2025; 185 documents were identified in English (with 7 duplicates) and 104 in Spanish (with 34 duplicates). After filtering, 178 studies in English and 70 in Spanish were evaluated; of these, 14 full texts were reviewed in each language, and 5 were excluded from each group. Finally, 9 articles in English and 9 in Spanish were included, along with 10 additional documents identified in Google Scholar, for a total of 28 articles analyzed. The results show that urban wastewater constitutes a critical reservoir of multidrug-resistant Enterobacteriaceae, including Escherichia coli and Klebsiella pneumoniae, carriers of genes associated with mechanisms such as ESBL, AmpC, carbapenemases, and plasmid resistance. It is concluded that poor management of domestic and hospital effluents, along with the presence of antibiotics and heavy metals, favors the selection and spread of antimicrobial resistance. These findings highlight the need to strengthen environmental microbiological surveillance and implement integrated regional strategies that contribute to the adequate control and treatment of wastewater in Latin America.
