Staphylococcus aureus can be found in normal flora of the skin and mucous membranes of humans. It features easy dissemination and high pathogenicity through multiple mechanisms of action. The agents of infections of both superficial and deep type. They often lead to septicemia and death of the patient. Objective: The indiscriminate use of antibiotics has led to the creation of resistant microorganisms, with the aim of this study was to compare in vitro the degree of effectiveness of beta-lactam antibiotics and glycopeptide in the inhibition of Staphylococcus aureus by comparing its effectiveness in surgical wound infection. Methods: We used pure cultures of Staphylococcus aureus. In the conduct of the trial were selected antimicrobials amoxicillin, oxacillin, cefepime, cefotaxime, cephalothin and vancomycin. Conclusion: The test strains were resistant to amoxicillin and susceptible to all antimicrobials tested.
