Resumen

NORIEGA, Luis Miguel et al. Community acquired infections with methicillin resistant strains of Staphylococcus aureus: Report of five cases. Rev. méd. Chile [online]. 2008, vol.136, n.7, pp.885-891. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872008000700010.

Community acquired infections with methicillin resistant strains of Staphylococcus aureus (MRSA) infections have a more aggresive clinical course and involve mostly skin and lungs. These infections appear as outbreaks among prisoners, spoñsmen, men having sex with men and military personnel. The higher aggressiveness of these strains is due to the production of several toxins, mainly Panton- Valentine leukocidine. The detection of the gene that codes for this toxin is a distinctive feature ofthese strains. We report five patients with community acquired MRSA infections. The clinicalpresentation was a skin infection in all. One patient had a pleuropneumonia in addition. Apart for resistance to beta-lactam antimicrobials, the strains were resistant to erythromycin and ciprofloxacin. Patients were treated with vancomycin, clotrimoxazole or intravenous clindamycin with a good evolution. An epidemiológical surveillance for community acquired MRSA strain infections should be started and measures to adequately treat infected patients and avoid dissemination should be implemented
