“…A study by Obire and Guda (2002) [ 38 ] demonstrated the presence of species belonging to the genera Klebsiella , Citrobacter , Escherichia and Enterobacter in leachates from a landfill in Nigeria, which is consistent with the results found in this study. Although species belonging to these genera have been associated with fecal contamination [ 39 ], their presence in highly complex matrices such as leachates is [ 40 ] mainly associated with their ability to tolerate and bioremediate heavy-metal-contaminated environments [ 41 , 42 , 43 , 44 , 45 , 46 ].…”

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 Enterobacterales isolated from a leachate treatment plant located in Cali, Colombia. Detection was performed using selective culture media, bacterial identification using Matrix-Assisted Laser Desorption/Ionization-Time-Of-Flight (MALDI-TOF, bioMérieux) and by sequencing the gene coding for the 16S ribosomal RNA subunit when discrepancies were observed between phenotypic characteristics and MALDI-TOF. Antibiotic sensitivity profiling was determined using the automated VITEK®2 system (bioMérieux). Twenty-one isolates were obtained, of which Klebsiella pneumoniae was the most frequent (23.8%), and 34% of the isolates showed decreased sensitivity to beta-lactam antibiotics such as cefoxitin, ampicillin/sulbactam and piperacillin/tazobactam. These findings suggest that leachates from landfills could be a reservoir of pathogenic bacteria carrying antibiotic resistance determinants, so periodic microbiological characterization of these effluents should be performed, promoting the One Health approach.

“…The P. pentosaceus strain HN10 was isolated from fermented foods, which achieved maximum growth rate at 50 g/L NaCl [12]. Another LAB detected and isolated from various environmental niches, such as soil [13], or food [14] sources is Enterococcus faecium. Three E. faecium strains isolated by fermented soybean paste containing 25.50 g/L NaCl, have been reported to grow in up to 70 g/L NaCl [15].…”
