Perfiles de susceptibilidad antimicrobiana en bacterias aisladas en cultivos agrícolas de la cuenca del Río Chambo.

Abstract

Foodborne illnesses have increased in recent years, derived from the consumption of agricultural products contaminated with pathogenic bacteria resistant to antibiotics.To identify the antimicrobial resistance profiles of pathogenic bacteria isolated in agricultural crops from the Chambo river basin. A total of 12 samples of vegetables and vegetables collected from agricultural areas of six geographical points near the Chambo River were analyzed. The isolation and identification of the bacteria was carried out by means of conventional tests culture media, together with biochemical tests. The antibiotic resistance profile was determined by the agar disk diffusion method. (12/14) 85.7% human pathogenic bacteria belonging to the Enterobacteriacea family were identified, including: Citrobacter freundii, Citrobacter amalonaticus, Enterobacter cloacae, Proteus vulgaris, Klebsiella oxytoca and (2/14) 14.3% corresponding to Enterococcus faecalis. 50% of the Enterobacteriaceae were resistant to 3rd generation cephalosporins (ceftriaxone and cftazidime), 50% to kanamycin and 25% to imipenem, gentamicin and trimethoprim sulfamethoxazole. The results obtained indicate a high contamination of agricultural crops dumped with irrigation water from the Chambo river basin by species of nterobacteriaceae and E. faecalis; with high percentages of resistance to antibiotics for clinical use.
