Infection by Acinetobacter spp. in the University Hospital "Comandante Faustino Pérez Hernández" of Matanzas. 2011-2012

Abstract

Infections associated to the sanitary care are serious public health problems at the international level because of their frequency and high mortality. In the last ten years, Acinetobacter spp. has emerged as an important nosocomial opportunistic pathogen. Among these species, A. baumanii (B Ab) is the main isolated species covering as many as 92 % of the nosocomial bacteremias. Most of the reports of nosocomial bacteremias by A. baumanii (B Ab) are outbreaks in adult patient intensive care units. It has been reported a boost of this germ antimicrobial resistance. We carried out a cross sectional, descriptive, observational study on Acinetobacter spp. infection, in the University Hospital “Comandante Faustino Pérez Hernández” of Matanzas municipality, from October 2011 to July 2012. Taking into account the absence of a previous study in Matanzas on infections caused by this microorganism, we decided identifying the Acinetobacter spp. incidence according to biological samples and coming-from service and identifying its sensibility/resistance, allowing the instauration of the efficacious treatment of the patients who carry this bacterium, considering the susceptibility pattern found in the study. The most frequently found species was A. baumanii, mainly in endotracheal secretions and hemo-cultures, most of them coming from Intensive Therapy Units, being this service the one contributing with more quantity of multidrug resistant stocks. We found a bigger sensibility to antimicrobials that are not considered first line ones like doxycycline, tetracycline and trimetoprim-sulfametoxazole.
