[An epidemic strain of Acinetobacter baumannii in two long-term care facilities].

This study describes an epidemic strain of Acinetobacter baumannii (AB) in two long-term care facilities. Assessment was focused on the spreading modalities of AB infection, the risk of acquiring the infection from colonized patients, the multidrug-resistant features, the clinical characteristics of affected patients, and the average length of hospital stay prior to and after AB infection. The effects of AB spreading among the healthcare operators and the environment are also evaluated, along with a description of the clinical course and outcome, and the efficacy of implemented preventive measures. AB is an opportunistic pathogen with increasing relevance in a variety of nosocomial infections.
