Antimicrobial resistance bacteria, including Escherichia coli, are widespread and pose a global health and economic burden. Monitoring fecal microbiota is important as it can serve as a potential source of resistant E. coli due to gene transfer between different bacteria. An analysis of 150 E. coli isolates from environmental, animal, and human samples in rural areas of Panama revealed high resistance to tetracycline and the presence of plasmid-associated tetA and tetB genes, suggesting the horizontal transfer of resistance genes within the community.
Antimicrobial resistance bacteria are nowadays ubiquitous. Its presence has been reported in almost every type of source, from water for agricultural and recreative use, water distribution pipes, and wastewater, to food, fomites, and clinical samples. Enterobacteriaceae, especially Escherichia coli, are not the exception, showing an increased resistance to several antibiotics, causing a global health and economic burden. Therefore, the monitoring of fecal microbiota is important because it is present in numerous reservoirs where gene transfer between commensal and virulent bacteria can take place, representing a potential source of resistant E. coli. In this work, antibiotic resistance profiles of 150 E. coli isolates from environmental, animal, and human samples, collected in three rural areas in Panama, were analyzed. A total of 116 isolates were resistant to at least one of the nine antibiotics tested. Remarkably, almost 100% of these exhibited resistance to tetracycline. Plasmid-associated tetA and tetB genes were detected in 42.86% of the isolates analyzed, tetA being the most prevalent. These results suggest that tetracycline resistance would be used as a convenient indicator of genetic horizontal transfer within a community.
