Nasal carriage of Staphylococcus aureus is an important risk factor for nosocomial and community-acquired staphylococcal infections. We investigate the prevalence of community-acquired methicillin-sensitive (CA-MSSA) and -resistant (CA-MRSA), including inducible dormant (ID)-MRSA S. aureus, and genotypes of MRSA strains of nasal cultures from 1,108 university students attending Selcuk Universit...

BACKGROUND: Community-acquired methicillin-resistant Staphylococcus aureus (CA- MRSA), a novel strain of MRSA, has recently emerged and rapidly spread in the community. Invasion into the hospital setting with replacement of the hospital-acquired MRSA (HA-MRSA) has also been documented. Co-colonization with both CA-MRSA and HA-MRSA would have important clinical implications given differences in ...

Background: Staphylococcus aureus, particularly methicillin resistant (MRSA), is a common pathogen among patients receiving hemodialysis. To understand MRSA carriage rate among these patients in different hospital levels, we conducted this study. Materials and Methods: From January 2011 to June 2011, two nasal samplings with a 3-month interval were obtained from 161 patients (totally 265 sampli...

Nasal and rectal cultures were taken from all patients with methicillin-resistant Staphylococcus aureus identified on routine cultures obtained because of clinical indications. Of 117 patients studied over a 3-year period, 70 (60%) had rectal colonization and 62 (53%) had nasal colonization. Rectal colonization, probably reflecting gastrointestinal carriage, may be a source of transmission of m...

BACKGROUND AND OBJECTIVES Acquired antimicrobial resistance is commonly attributed to regimens that expose bacteria to subinhibitory concentrations; consequently, eradication of susceptible cells is advocated. The mutant selection window hypothesis predicts that resistance can be acquired even when inhibitory concentrations are exceeded and susceptible bacteria are eradicated. The objective was...

background nasal colonization of healthy children with staphylococcus aureus is an important risk factor for different infections. detection of colonized individuals with methicillin resistant s. aureus (mrsa) and its eradication is the proper prevention strategy for infection spread in the community and health-care centers. objectives the aim of this study was to determine the prevalence, asso...

conclusions the occurrence of multidrug-resistant s. aureus in the elderly cohort indicates their capacity to serve as reservoirs for these strains, which could facilitate the dissemination of mrsa into the community. therefore, decolonization and the implementation of measures to prevent the spread of this organism are necessary. results fifty (21.7%) s. aureus strains were identified among th...
