摘要
objectives: to assess colonization by staphylococcus aureus sensitive and resistant to methicillin found in the saliva of nurses and, to recognize the mupirocin profile of resistance. methods: it was collected three saliva samples of 356 (94.2%) professional research participants, totaling 1068 samples processed. all ethical aspects were covered. microbiological analysis included the phenotypic identification, according to the standards of the clinical and laboratory standards institute. results: in the first collection were obtained 73 individuals colonized by staphylococcus aureus, 48 in the second and 37 in the third, totaling 158 samples of staphylococcus aureus. of these, 24 (15.2%) were resistant to oxacillin and 30 resistant to mupirocin (18.9%). mupirocin resistance was observed sharply in the staphylococcus aureus resistant to methicillin (mrsa); of 24 mrsa, 17 (70.8%) were resistant to this antibiotic. conclusion: the results indicated that mupirocin resistance is a major problem since this antibiotic is an excellent ally in the measures taken to control infection in health services.
