Detecció de bacteris resistents a antibiòtics en aigües d’estacions depuradores


Belenguer Batllerià, Maria


Antibiotics are partially metabolized (30-90%) in the human and animal body, this causes significant amounts of antibiotics to be excreted unchanged or as active metabolites through urinary and / or fecal excretion in the sewage system. The presence of these antibiotics in wastewater can promote the emergence of resistant bacteria. In addition, it is considered that the biological purification processes of the treatment plants create a potentially suitable environment for the development and dissemination of resistance in bacteria because they are constantly mixed with other bacteria and with antibiotics. In this work, the resistances of Escherichia coli and coliforms to ampicillin, sulfamethoxazole, levofloxacin, ciprofloxacin and ofloxacin present in the wastewater will be determined, at the entrance of different treatment plants (Amposta, San Carlos de la Ràpita and la Sènia ) with biological purification processes and at the exit of these to know how this system affects the resistance of the different antibiotics.
