Colonization of resistant faecal aerobic gram-negative bacilli among geriatric patients in hospital and the community.

Among the elderly most infections are caused by organisms of faecal origin. The study of the resistance of such Gram-negative bacilli should therefore be a priority. In this study, we determine the occurrence of resistance to five antimicrobials commonly used in geriatric outpatient care, and compare it with long-term and short-term hospitalized geriatric patients treated and not treated with antimicrobials.
