NODARSE HERNANDEZ, Rafael. Estafilococos multirresistentes: uso del disco de oxacillín como marcador de resistencia a antibióticos. Rev Cub Med Mil [online]. 2001, vol.30, n.1, pp.7-10. ISSN 0138-6557.

The susceptibility in vitro of strains belonging to the genus Staphylococcus was studied by using different antibiotics. Emphasis was made on vancomycin and penicillin based on the degree of resistance to oxacillin. 200 strains of staphylococci were used. l00 of them belonging to the Staphylococcus aureus species and the other 100 to coagulase-negative staphylococci. The strains had an intrahospital and community origin. The rates of resistance observed among the studied strains, mainly the coagulase-negative staphylococci, were as follows: significant to oxacillin, very high to penicillin and incipient to vancomycin. The oxacillin-resistant strains showed the highest values and a wide spectrum of resistance to antibiotics.
