Patients are classified according to the number of days in ICU at the date of BAL; three patients had BAL performed 1,2, and 4 days before ICU admission. BAL: bronchoalveolar lavage; BALF: BAL fluid; F: female; D28: 28th day; HIV: human immunodeficiency virus; ICU: intensive care unit; M: male; MRSA/MSSA: methicillin-resistant/sensible Staphylococcusaureus; NA: non available.

At the date of BAL.

D28 means the 28th day following ICU admission.
