The objectives of the present study were to investigate the rate of S.aureus nasal carriage and molecular characteristics in hospital and community settings in Bobo Dioulasso, Burkina Faso. Nasal samples (n = 219) were collected from 116 healthy volunteers and 103 hospitalized patients in July and August 2014. Samples were first screened using CHROMagar Staph aureus chromogenic agar plates, and...

Staphylococcus aureus is a gram positive, nonmotile bacterium which normally colonizes in skin and mucosa of human and animal, transmitted by direct contact or via contaminated surfaces, which causes infections like skin infections , respiratory infections and food poisoning. Methicillin is a narrow spectrum betalactam antibiotic of the penicillin class which was previously used for the treatme...

OBJECTIVES To compare the performance of the automated Vitek 2 system, the disc diffusion method and a home-made mupirocin screen agar (MSA) to detect mupirocin resistance in methicillin-resistant Staphylococcus aureus (MRSA) isolates. METHODS A total of 125 MRSA isolates were tested. The level of mupirocin resistance was determined by agar dilution and Etest techniques (gold standard), by th...

introduction: methicillin-resistant staphylococcus aureus (mrsa) can cause serious and life-threatening hospital- and community-acquired infections. colonized and infected patients represent the most important reservoir of mrsa in health care facilities. therefore, in this study, mrsa isolates collected from shohada hospital in tabriz were evaluated for the frequency of meca gene and their anti...

Forty-two medical centers from throughout the United States participating in a longitudinal surveillance program were asked to submit 100 consecutive Staphylococcus aureus isolates during July to December 2011. Susceptibility testing using CLSI broth microdilution and mecA detection by PCR analysis was performed on the 4,131 isolates collected. Methods employing Etest glycopeptide resistance de...

RATIONALE Colonization of lower airways by Staphylococcus aureus is a risk factor for the development of ventilator-associated tracheobronchitis (VAT) and ventilator-associated pneumonia (VAP). However, little is known about the virulence factors of methicillin-sensitive and -resistant S. aureus (MSSA and MRSA) that may influence host colonization and progression to VAT and VAP. OBJECTIVES We...

Introduction: Methicillin-Resistant Staphylococcus aureus (MRSA) is responsible for an increasing number of serious hospital- and community-acquired infections. USA300 is known to be the most common cause of community-acquired infections, but recently there have been some reports on hospital-acquired infections caused by this strain. Methods: Totally 171 isolates of S. aureus were collected fro...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is recognized as a cause of nosocomial infections in both human and veterinary medicine. Studies that examine the nasopharynx and guttural pouches of the horse as carriage sites for MRSA have not been reported. HYPOTHESIS/OBJECTIVE MRSA colonizes the nasopharynx and guttural pouch of horses. To determine the prevalence of MRSA in e...

background methicillin -resistant staphylococcus aureus (mrsa) is associated with serious infections. having the ability of biofilm-formation decrease their susceptibility to antibiotics. objectives the aim of this study was to determine the prevalence of biofilm formation among mrsa isolated from nasal carriers in the beheshti teaching hospital in kashan, iran. materials and methods a cross-se...

conclusions high hvr diversity among the studied mrsa isolates could be a result of insufficient or inadequate infection-control protocols in tabriz hospitals. moreover, the high number of hvr genotypes showed that hvr typing can be used along with other typing methods in epidemiological studies of mrsa as a useful tool for monitoring, tracking contaminations, and controlling infections in hosp...
