Infections bronchopulmonaires à Stenotrophomonas maltophilia et à Acinetobacter baumannii

摘要: Stenotrophomonas maltophilia and Acinetobacter baumannii are both non-fermenting ubiquitous Gram-negative bacilli. The incidence of lower respiratory tract infections related to these microorganisms is increasing, especially in intensive care units. Their capacity acquire resistance against several antimicrobials challenging for clinicians microbiologists. Despite their low virulence, pathogens responsible colonization infection patients with comorbidities, immunosuppression, critically ill patients. S. A. mainly identified nosocomial infections: ventilator-associated pneumonia, bacteremia surgical wound infection. Infections microorganism associated high mortality morbidity. Trimethoprime-sulfamethoxazole carbapenem the first line treatment respectively. However, increasing rate agents results difficulties treating pathogens. New antimicrobial further randomized studies needed improve infections. Prevention spared multidrug-resistant bacteria mandatory, including hand-hygiene, environment cleaning, limited usage large spectrum antibiotics.
