ABSTRACT

Bacterial resistance to antibiotics is a major public health problem around the world causing high rates of morbi-mortality and economic problems in hospital settings. Major bacterial causing nosocomial infections are: extended-spectrum b-lactameses (ESBL) producing enterobacteria, methicillin resistance Staphylococcus aureus, coagulase negative Staphylococcus, metallo b-lactamases (MBL) producing Pseudomonas aeruginosa, Streptococcus pneumoniae, Enterococcus spp, Acinetobacter baumani. This last bacteria is not very often isolated in hospital settings yet, but it is multi-resistance pathogen causing high mortality. Helicobacter pylori, which is not a nosocomial pathogen but is associated to gastric diseases (from gastritis to gastric cancer). Infections prevention, to obtain an accuracy diagnostic and effective treatment, use antibiotic wisely and pathogen dissemination prevention (hand washing), are important steps to control the bacterial resistance.
