Fifty circulating strains of Staphylococcus aureus of clinical origin were characterized by their drug susceptibility to 15 antimicrobials through the method of radial diffusion in Mueller Hinton medium. Also, beta-lactam production was determined by acidimetric and chromogenic methods as well as the presence of methicillin-resistant strains. It was confirmed that 32% of strain was susceptible to tested antimicrobials, the most effective of which were imipenem, norfloxacyn, and amikacyn for 98,
