Bacterial resistance is an increasing health problem worldwide. A descriptive, retrospective study was conducted in the Laboratory of Clinical Microbiology of the Municipal Center of Hygiene and Epidemiology of Güines municipality, from January to December 2005, to know the susceptibility to the antimicrobial elective agents of 750 strains that included the following microorganisms: Staphylococcus aureus (n=250), Escherichia coli (n=250) and Pseudomonas aeruginosa (n=250), isolated from different clinical samples (ear secretion, skin lesions, wound pus, pharynx and urine) from ambulatory patients with signs and symptoms of infection from 5 municipalities of Eastern Havana. High levels of resistance were found in the strains of Staphylococcus aureus to penicillin, oxacillin, and erythromycin; in Escherichia coli to trimethoprim-sulphamethoxazole, nalidixic acid and ampicillin; and in the case of Pseudomomas aeruginosa no high levels of resistance to the studied drugs were reported. The results show the need to improve and continue the epidemiological surveillance of the resistance to antimicrobial agents.
