Staphylococcus aureus nasal carriage in hemodialysis centers of Fez, Morocco.

Background And Objectives: Staphylococcus aureus (S. aureus) nasal carriage may be responsible for some serious infections in hemodialyzed patients. The main target of this study was to estimate the prevalence of S.

Staphylococcus aureus nasal carriage in a Moroccan dialysis center and isolates characterization.

Staphylococcus aureus, which has its ecological niche in the anterior nares, has been shown to cause a variety of infectious diseases mainly for patients in hemodialysis units. We performed this study to evaluate the prevalence of nasal S. aureus carriage among hemodialysis outpatients, to determine the antimicrobial susceptibility of isolates, to characterize the virulence genes, and to identify associated risk factors.

Characterization of fusidic acid-resistant Staphylococcus aureus isolates in the community of Casablanca (Morocco).

Resistance to fusidic acid in Staphylococcus aureus is caused by mutation of the elongation factor G (EF-G) encoded by fusA or by expression of a protein, encoded by fusB or fusC, that protects the drug target. Other mechanisms involved in this resistance are mutations in the riboprotein L6 operon within rplF. The aim of this study was to determine the prevalence and mechanisms of resistance to fusidic acid in clinical isolates of S.
