Abstract

Infections, the microorganisms responsible for them, and the use of antimicrobials in hospital and community environments are of interest to all medical specialties. A descriptive and retrospective study of Pseudomonas aeruginosa isolated from skin and wounds secretions of hospitalized patients at the Arnaldo Milian Castro Provincial University Hospital in Santa Clara from January 2004 to December 2008 was conducted with the objective of characterizing these isolates, identifying its frequency, describing its distribution in different medical services and determining the levels of antibiotic resistance. The data were collected from the records books of the microbiology laboratory. The isolates of microorganisms in this period were a total of 6777. Three predominated: Staphylococcus aureus (23.5%), Acinetobacter spp (13.4%), and the sample producing the data, Pseudomonas aeruginosa, with a total of 881 isolates for 13.1%. The distribution according to medical services was analyzed in this species. It was found that the surgical services have a higher incidence of infections caused by Pseudomonas aeruginosa (79.2%) than the clinical services (20.8%). It predominated mainly, in decreasing order, in the Boards of Angiology, Orthopaedics, and Plastic Surgery and Care of Burn Patients. Pseudomonas aeruginosa showed higher levels of resistance to carbenicillin, ticarcillin and gentamicin, while the lowest levels were shown to amikacin, ceftazidime and ciprofloxacin.
