A descriptive cross-sectional study in patients with hard-to-heal venous ulcers, whose objective is to identify the prevalence of Gram-negative rods (GNR) in venous ulcers presenting clinical signs of infection; analyze the susceptibility profile of such ulcers and detect ESBL, AmpC and metallo-?-lactamase production. We identified 69 individuals. The samples were gathered by means of an interview, clinical exam, photographic record and a swab of the lesions. Specimens were submitted to laboratorial evaluation for microbiological analysis. A total of 98 lesions were evaluated, of which BGN presented in 74.5%. There was a prevalence of P. aeruginosa and Escherichia coli. The mircoorganisms were sensitive to most antimicrobials. In terms of resistance, tetracycline and cefoxitine were discarded. ESBL was not detected; AmpC was verified in 37.5% of the CESP group and metalo-?-lactamase in 8.0% of P. aeruginosa. Our study points to the need for microbiological vigilance of patients with hard-to-heal venous ulcers. doi: 10.5216/ree.v16i2.24670.
