Introduction Staphylococcus aureus has been appointed as one of the most agent cause nosocomial infection. There are evidences showing that many infections are preceded by one or more sites colonised by microorganisms.

In the era of HAART, people living with HIV/aids require less hospitalisation processes. However, in many cases it is necessary and hospital environment can be a further injury for their condition, because of their greater vulnerability to nosocomial microorganisms. The study aims to identify the presence of nasal colonisation by Staphylococcus aureus in people living with HIV/AIDS after seven days of hospitalisation.

Methods It´s a cross-sectional study undertaken in two units specialised in attending people living with HIV/AIDS, in the period of August-2011 – October 2012. Socio-demographic and clinical data collected through individual interviews and from the medical records. Samples of nasal secretion were collected with Stuart swabs on the hospital admission and seven days after hospitalisation. All ethical aspects were respected.

Results Of the 227 people living with HIV/AIDS that hospitalised in this period, 33 (14.5%) identified with nasal colonisation with Staphylococcus aureus. Of these, 10 (24.9%) showed no nasal colonisation with Staphylococcus aureus on the first day of hospitalisation. In addition, 6 (60%) identified oxacillin resistance cepa.

Conclusion Thirty three (14,5%) people living with HIV/AIDS were identified Staphylococcus aureus after seven days of hospitalisation. These results allow contributing to more investigations and implementation of measures to prevent and control this pathogen in this population.
