ICU, intensive care unit; Med, medical unit(s); ICU-P, polivalent ICU; ICU-S, postsurgical ICU; OBS, observation; NC, neurosurgery; PED, pediatrics; GIN, gynecology; CET, cranium-encephalic traumatism; CSF, cerebrospinal fluid; NK, origin not known.
Number of pulsotyped isolates (in 2003 and 2004, only representative isolates from the different hospital units were included). Clones are designated by capital letters and refer to A. baumannii isolates.
The respiratory tract includes sputum, bronchial secretions, and tracheal aspirate.
P was <0.01 for the difference between the two values (after Bonferroni's adjustment) for 2001 and 2002, and P was <0.001 for the difference between the two values for 2002 and 2003. No significant differences were observed between 2003 and 2004 (P = 0.73)
