Antimicrobial sensitivity and BLEE gene in gut microbiota enterobacteria from children treated at Llapa health center, San Miguel, Cajamarca – 2023

Abstract

To determining the sensitivity/resistance status of the intestinal microbiota of children from Llapa - Cajamarca, 30 bacterial isolates from feces were analyzed by microbiological and molecular methods. Sensitivity to cefuroxime, cefotaxime or ciprofloxacin (3.3 %, each) was the least common; sensitivity to ampicillin was null. Resistance to ampicillin (90 %), cefotaxime (80 %) and sulphamethoxazole-trimetropime (77 %) was the most common. E. coli was the most abundant species. The blaCTX-M gene was the most frequent, which is partly related to the phenotypic results.
