Introduction:

Staphylococcus aureus is an important cause of morbidity and mortality in the world. In Cuba, it is a germ to be taken into account as a cause of nosocomial infection.

Objective:

To characterize, clinically and epidemiologically, a sample of patients with infections caused by Staphylococcus aureus.

Methods:

An observational, descriptive and cross-sectional study was conducted at the Military Hospital "Dr. Mario Muñoz Monroy "of Matanzas, during the period from January to December of the year 2014. The population was constituted by all the patients hospitalized with the diagnosis of infection by Staphylococcus aureus (120 cases), identified by the department of Microbiology; then the medical records from which the information was obtained were reviewed.

Results:

There was a predominance of males (64.2%) those over 60 were the most affected (36.7%). Diabetes mellitus was the most frequent associated disease (40.8%) and the majority of infections were of community origin (67.5%). Positivity predominated in samples taken from skin lesions and blood cultures with 50.8% and 19.2%, respectively. Low sensitivity to vancomycin (49.2%) and cotrimoxazole (38.3%) was evidenced.

Conclusions:

Staphylococcus aureus infections were more frequent in geriatric male patients of out-of-hospital origin. The germ showed high resistance to antibiotics and of these, the aminoglycosides showed the highest antimicrobial sensitivity.
