Antimicrobial resistance of methicillin-resistant Staphylococcus aureus at the Dr. Gustavo Aldereguía Lima Hospital

Abstract

Foundation: Multidrug-resistant bacteria are a growing problem in hospitals around the world. Methicillin-resistant Staphylococcus aureus is the germ responsible for a considerable part of infections both inside and outside hospitals. Objective: To describe the antimicrobial resistance of methicillin-resistant Staphylococcus aureus. Methods: A descriptive study with clinical samples of patients attended at Dr. Gustavo Aldereguía Lima Hospital, Cienfuegos, in the year 2014. For the 142 clinical samples analyzed, the service of origin, type of sample and bacterial resistance were studied. Samples were analyzed in the Laboratory of Microbiology of the Hospital. Cefoxitin discs were used for the detection of resistance by the Kirby Bauer diffusion method.Results: Methicillin-resistant Staphylococcus aureus was most frequently isolated in hospitalized patients (55.0%), mainly causing skin and mucosal infections (50.6%). He showed greater resistance to erythromycin and azithromycin, both in hospitalized and outpatient patients. 15 patterns of resistance were obtained, of which the pattern azithromycin, erythromycin, ciprofloxacin, was the most frequent (70 isolates).Conclusion: The high antimicrobial co-resistance patterns confirmed the multidrug resistance character of methicillin of Staphylococcus aureus, which showed resistance to more than two types of antibiotics in the analyzed samples.
