Prevalence of qacA/B Genes and Mupirocin Resistance Among Methicillin-Resistant Staphylococcus aureus (MRSA) Isolates in the Setting of Chlorhexidine Bathing Without Mupirocin.
OBJECTIVE We aimed to determine the frequency of qacA/B chlorhexidine tolerance genes and high-level mupirocin resistance among MRSA isolates before and after the introduction of a chlorhexidine (CHG) daily bathing intervention in a surgical intensive care unit (SICU). DESIGN Retrospective cohort study (2005-2012) SETTING: A large tertiary-care center PATIENTS Patients admitted to SICU who ...
متن کاملMulticenter evaluation of BBL CHROMagar MRSA medium for direct detection of methicillin-resistant Staphylococcus aureus from surveillance cultures of the anterior nares.
Active surveillance for methicillin-resistant Staphylococcus aureus (MRSA) is among the strategies recommended by the Society for Healthcare Epidemiology of America for control of nosocomial MRSA infections. Infection control and laboratory personnel desire rapid, sensitive, and inexpensive methods to enhance surveillance activities. A multicenter study was performed to evaluate a new selective...
متن کاملThe association between biocide tolerance and the presence or absence of qac genes among hospital-acquired and community-acquired MRSA isolates.
OBJECTIVES The MBCs of three commonly used hospital biocides [containing quaternary ammonium compounds (QACs), chlorhexidine gluconate and triclosan] were determined for clinical isolates of Staphylococcus aureus, which were also screened for genes encoding Qac efflux pumps. METHODS MBCs were determined by broth microdilution for 94 clinical isolates of S. aureus, including 38 hospital-acquir...
متن کاملNasal Colonization Rate of Community and Hospital Acquired Methicillin Resistant Staphylococcus Aureus in Hospitalized Children
Background & Aims: Prevalence of community and hospital acquired methicillin-resistant Staphylococcus aureus (MRSA) infection is increasing. The primary reservoir is the anterior nares; and nasal carriage is a risk factor for infection in a variety of populations. Infection due to hospital-acquired colonization is different from community acquired in clinical manifestations and antibiotics susc...
متن کاملPrevalence of resistance and toxin genes in community-acquired and hospital-acquired methicillin-resistant Staphylococcus aureus clinical isolates
Objective(s): Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major health hazards and became of greater public health concern since the emergence of community-acquired MRSA. This work aimed to study the prevalence of mecA, femA, femB, lukS-PV, lukF-PV (PVL), intI, and intII genes among community-acquired (CA) hospital-acquired (HA) MRSA to increase vi...
