RESUMO
In this article, a case of decubitus ulcer infection caused by an extended-spectrum beta-lactamase-producing Proteus mirabilis strain, successfully treated with oral amoxicillin-clavulanate (1-month therapy) is described. This article focuses on diffusion and clinical effect of extended-spectrum beta-lactamases-producing Proteus mirabilis on treatment of gram negative lower extremity infections.

We report a case in which Escherichia fergusonii, an emerging pathogen in various types of infections, was associated with cystitis in a 52-year-old woman. The offending strain was found to be multidrug resistant. Despite in vitro activity, beta-lactam treatment failed because of a lack of patient compliance with therapy. The work confirms the pathogenic potential of E. fergusonii.
