TITLE:

SUMMARY:

The elderly population, individuals aged 60 years or older, is the fastest growing demographic in the world. With aging, the immune system becomes less efficient, generating systemic impairments in the elderly, making them more vulnerable to possible infections. Thus, the objective of this study was to evaluate the prevalence of S. aureus and MRSA colonizing the oral environment of bedridden and domiciled elderly people, as well as to evaluate factors associated with this population. For this purpose, 263 elderly people were visited in their homes in the city of Natal/RN. Samples of the oral environment were collected with the aid of swabs, plated on the selective culture medium mannitol salt agar and colonies suggestive of Staphylococcus aureus were reisolated and later identified through conventional laboratory tests and mass spectrometry (MALDI-TOF). The identification of the MRSA strain was performed by the disk diffusion method, using the antimicrobial cefoxitin. The same technique was used to assess susceptibility to other antimicrobials. Data related to sociodemographic factors and self-perceived health were collected through a questionnaire. The prevalence of elderly individuals colonized by S. aureus was 13.3% (n=35) and for MRSA it was 1.5% (n=4). All MRSA were sensitive to other classes of drugs tested. Statistical tests showed an association between the variables male gender, bedridden elderly individuals, poor general health and difficulty in eating and the presence of S. aureus. The presence of S. aureus colonizing elderly individuals may represent a health risk to this population, especially due to their greater immunological vulnerability.
