Description
Summary:This paper aims to evaluate drug resistance of bacteria isolated from equipment placed close to patients in an Intensive Care Unit of a hospital in Caruaru/Pernambuco, Brazil. This is a cross-sectional study. The samples were collected with swabs moistened with Trypticase Soy Broth, which were then cultured in sheep blood agar and MacConkey agar. The phenotypic identification performed was based on the morphology of the strains and biochemical results. The drugs resistance analysis was based on Kirby-Bauer's Disk Diffusion protocol. A rate of 94.4% of the analyzed equipment was contaminated. The most frequently isolated microorganisms were: Acinetobacter sp., Staphylococcus aureus and Pseudomonas sp. Just about 75% of Acinetobacter sp. was resistant to piperacillin associated to tazobactam, meropenem and levofloxacin. Similarly, 36.3% of S. aureus showed resistance to oxacillin and 10% of Pseudomonas sp. was resistant to the drugs tested. Most of the microorganisms presented high levels of resistance to the drugs.
