• Abstract:

  Staphylococcus aureus is one of the leading pathogens causing health

  related infection as it is responsible for the microbiota of the skin of humans. Thus, the

  control and detection of S. aureus carriers are of significant importance when it comes

  to health students, since they can be attended by a multiresistant bacterium. Thus the

  objective of this work was to verify the prevalence of blaOXA10 and mecA genes in strains

  of multiresistant S. aureus isolated from the hands and nasal cavity of health students.

  Hands and nasal cavity were searched for 140 students. The isolated strains were

  identified and submitted to antibiogram, phenotype research of extended spectrum

  enzymes (ESBL) and the blaOXA10 and mecA genes.Of the 140 students, 62 (44.3%)

  were colonized by S. aureus (30 had in their hands, 18 in the nasal cavity and 14 in

  the hands and in the nasal cavity), totaling 76 strains of S. aureus. Most S.aureus

  strains were resistant to ampicillin (73.7%) and penicillin (50%). Only one strain was

  positive for ESBL production. The prevalence of the blaOXA10 and mecA genes in the

  strains was 57.9% (44) and 19.3% (15) respectively. These results indicate that health

  students should be constantly trained to prevent transmission of multiresistant strains

  of S. aureus
