Abstract
Three health Brazilian families were examined for their oral carriage of Staphylococcus aureus the most common persistent human pathogen. The mean level of S.aureus colonization was high 56.2% and 25.9% of the individuals were methicillin-resistant S. aureus (MRSA) carriers. However, a low level of resistance to eight antimicrobial agents were found, except for penicillin (85.1%), erythromycin (40.7%) and amoxicillin (22.2%).References
