| Resumo: | Objective
To analyze nasal colonization by Staphylococcus sp. its resistance to methicillin, and associated factors in inpatients.
Methods
Nasal sample collection, antimicrobial susceptibility tests, and analysis of medical records of inpatients (n=71) were performed, and a questionnaire was applied. Data were analyzed by descriptive and inferential statistics using the chi-square, Student’s t, and Mann-Whitney tests (α=5%).
Results
Nearly half (44.4%) of the patients who were significantly associated with prolonged antibiotic treatment (p=0.02) was infected with methicillin-resistant Staphylococcus sp.. A significant association was observed between patients with sensitive strains and absence of antibiotic treatment prior to sample collection (p=0.02) or absence of wounds (p=0.003).
Conclusion
Strains of methicillin-resistant Staphylococcus sp. were found, and there was no significant difference between the S. aureus species and the coagulase-negative Staphylococci groups, which indicates the degree of spread of methicillin resistance among different species of Staphylococcus. |
