Item Identificación de bacterias productoras de Betalactamasas de espectro extendido en fertilizantes orgánicos(Universidad Santiago de Cali, 2023) Espinosa Santa, Gabriela; Montero Castrillón, Paola Andrea; Correa Bermúdez, Adriana María (Directora); Falco Restrepo, Aura Dayana (Directora)Organic fertilizers have played a fundamental role nowadays due to their multiple benefits on soils and on the environment by not producing harmful chemicals for it, without leaving behind certain key factors such as their components to make them more natural, such as the waste produced by livestock. Thus, a search for enzymes encoded by third generation cephalosporin resistance genes was carried out by means of susceptibility tests, synergy tests and PCR from industrial and artisanal fertilizers, which are available for free sale to the public. The results indicated 100% presence of genes related to antibiotic resistance in the 19 isolates analyzed, 68.42% of which were identified as E. coli and 31.58% as K. pneumoniae, with the bla CTX-M gene standing out among them, being present in 84.21% of the isolates. In conclusion, it was confirmed that organic fertilizers can act as a possible source of dissemination of multiresistances.
