Abstract
SANMARTIN ORBE, Marcia Lucia; ANDRANDE TACURI, Carlos Fernando and ORELLANA BRAVO, Paola Patricia. Susceptibility of S. aureus strains isolated on hospital surfaces. Vive Rev. Salud [online]. 2021, vol.4, n.11, pp.233-245. ISSN 2664-3243. https://doi.org/10.33996/revistavive.v4i11.98.
Nasocomial infections by Staphylococcus aureus have a high prevalence, because this bacterium is part of skin microbiota of health personnel and patients. This microorganism for its ubiquity is present on surfaces and fomites becoming vectors for the transmission of infecions.
Objective
. Describe the antibiotic sisceptibility profile of S. aureus strains isolated from surfaces of hospital the city of Cuenca.
Materials and methods
. Is a quantitative cross sectional, descriptive, 200 samples were collected from different surfaces of hospital areas, in which S. aureus was identified through the amplification of nucA and femB genes. Phenotipic susceptibility to antibiotics was determined by the Kirby Bauer method.
Results.
6 strains of S. aureus were identified, distributes as follows: 2 strains in the emergency area (33.33%) and 1 (16.66%) in each of the areas: dressing rooms X-rays, ultrasound and dentistry. All of these isolates were resistant to: penicillin, oxacillin, and amoxacillin; sensitive to trimethoprim sulfamethoxazole, rifampin, tetracycline vancomycin and linezolid. In the case of gentamicin, it was found: 3 sensitive strains, 1 with intermediate sensitivity and 2 resistant.
Conclusion.
Six strains of S. aureus were isolates, in which the susceptibility to different antibiotics could be measured.
