RESUMO
Este trabalho objetivou caracterizar a resistência antimicrobiana de 43 cepas de Escherichia coli isoladas do açude Santo Anastácio (Fortaleza, CE), durante os meses de janeiro a abril de 2007. As cepas foram submetidas a testes de suscetibilidade a oito antimicrobianos, tendo 67,4% delas apresentado sensibilidade a todos. Observou-se resistência à tetraciclina (25,6%), ao sulfazotrin (18,6%), ao ácido nalidixíco (9,3%) e a ciprofloxacina (4,7%). Nenhuma resistência foi observada aos betalactâmicos. Nove (21%) cepas apresentaram multirresistência, com um percentual de 78% para resistência cromossômica e 56% para resistência plasmidial. A presença de bactérias resistentes pode estar relacionada ao lançamento de antimicrobianos nas águas através de esgotos, sendo que o uso inadequado dessas águas pode comprometer a saúde da população.
ABSTRACT
The aim of this study was to determine the antimicrobial resistance of 43 Escherichia coli strains isolated from the Santo Antonio weir (Fortaleza, CE, Brazil) from January to April 2007. Susceptibility tests performed with 8 antimicrobials indicated that 67.5% of the strains were susceptible to all of them. Resistance to tetracycline (25.6%), sulfazotrim (18.6%), nalidixic acid (9.3%), and ciprofloxacin (4.7%) was observed. The strains did not show resistance to betalactamics. Nine strains (21%) were multiresistant, the resistance being chromosome (78%) and plasmid (56%) mediated. The presence of resistant bacteria may be related to antimicrobials in the sewage discharged into the weir, and the inappropriate use of this body of water may pose human health risks.
