Identification of and Isolated from Leachate Ponds: Characterization of Their Antibiotic Resistance and Virulence-Associated Genes.

This study aimed to evaluate the antibiotic resistance of 22 environmental isolates and 1 isolate from landfill leachates in southwestern Colombia. Isolates were identified by Matrix-Assisted Laser Desorption/Ionization-Time-Of-Flight (MALDI-TOF), and 16S ribosomal RNA gene sequencing. Analysis of the susceptibility to six antibacterial agents by the Kirby-Bauer method showed susceptibility of all the isolates to ciprofloxacin and imipenem.

Beta-Lactam-Resistant Isolated from Landfill Leachates.

Antibiotic resistance is one of the main challenges worldwide due to the high morbidity and mortality caused by infections produced by resistant bacteria. In Colombia, this problem has been studied mainly from the clinical perspective; however, it is scarcely studied in the leachates produced in landfills. The objective of this study was to detect, identify and determine the antibiotic sensitivity profile of isolated from a leachate treatment plant located in Cali, Colombia.
