background: recent analyses of hospital outbreaks have documented the spread of resistance to imipenem, which is cur­rently a major problem among gram positive and gram-negative bacteria. the aim of this study was to describe the rate of gram- positive and gram-negative isolates resistance to imipenem as an antibiotic. methods: recorded files of 242 hospitalized patients with at least one sampl...
