Prevalence and Characteristics of Staphylococcus aureus Colonization among Healthcare Professionals in an Urban Teaching Hospital

Abstract

The observed prevalence of S. aureus and MRSA colonization among HCPs exceeds previously reported prevalences in the general population. The proportion of community-associated MRSA among all MRSA in this colonized HCP cohort reflects the distribution of the USA300 community-associated strain observed increasingly among US hospitalized patients.

Prevalence of Staphylococcus aureus and Lack of Its Lytic Bacteriophages in the Anterior Nares of Patients and Healthcare Workers at a Rural Clinic

“…38 This study's overall prevalence of S. aureus (24.3%) and MRSA (0.99%) is also similar to those noted for the U.S. population and published by Kuehnert et al, 28 who reported S. aureus and MRSA colonization prevalence estimates as 32.4% (95% CI, 30.7-34.1) and 0.8% (95% CI, 0.4-1.4), respectively. However, our study showed a lower prevalence rate (25.5% for S. aureus and 0% for MRSA) among HCE workers than previous studies, such as Elie-Turenne et al 39 who reported a 43.8% prevalence for S. aureus and a 15.2% prevalence for MRSA in healthcare professionals, and Barbosa et al 40 who reported a 5% MRSA prevalence in house staff in their study, all from surgical rather than medical house officers. In addition, Halablab et al 41 reported contact with healthcare workers as a risk factor for nasal colonization.…”

Detection and antibiotic resistance pattern of Staphylococcus aureusand (MRSA) isolated from healthcare workers Nares at three Gaza hospitals, Palestine

“…Increased rates of MRSA colonization among HCWs have at least 3 important implications. First, HCWs may become infected by their own MRSA carriage strains; second, they could serve as a route of cross-transmission to patients; and finally, they may introduce the pathogen into their communities [12]. Several studies in Arabic countries and worldwide have reported that the rate of the nasal carriage of S. aureus and MRSA among HCWs ranges from 10.1%-76% [10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

Hemodialysis Access Infections, Epidemiology, Pathogenesis and Prevention

“…More recent data are in agreement with this, and it is widely believed that nasal colonisation provides a natural reservoir that facilitates ongoing habitation and propagation of S. aureus in human populations. (Elie-Turenne et al, 2010;Mermel et al, 2010). Nasal application of mupirocin has been proven to eradicate nasal carriage of S.aureus in up to 98.5% of cases (Taal et al, 2006).…”
