Background and Aims: Emerging antimicrobial resistance is one of the major public health threats worldwide. It can result in increased morbidity and mortality rates along with increased treatment costs and hospitalization stays. Methicillin-resistant Staphylococcus aureus (MRSA) has become a global challenge. It is a major cause of nosocomial and community-acquired infections. Its prevalence va...

Strategies to monitor and control the spread of methicillin-resistant Staphylococcus aureus (MRSA) infections are dependent on accurate and timely diagnosis of MRSA in both hospital and community settings. In Latin America, significant diversity in diagnostic and susceptibility testing procedures exists at the regional, national and local levels. Various tests for S. aureus and MRSA are availab...

The aim of the present study was to estimate the impact of methicillin resistance on mortality in ventilator-associated pneumonia (VAP) due to Staphylococcus aureus. PubMed, Scopus and the bibliographies of the eligible studies were searched. The DerSimonian-Laird random effects model was used to determine the effect of methicillin resistance on mortality. Eight articles were included. Crude in...

INTRODUCTION The study aimed to investigate the resistance of methicillin resistant Staphylococcus aureus (MRSA), an indicator used in hospitals but isolated from faecal samples of children in the community, to commonly used antibiotics and antiseptic agents. METHODOLOGY S. aureus isolates were identified by phenotypic and genotypic techniques such as biochemical tests and polymerase chain re...

Twenty-five serial passages of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus and 50 passages of methicillin-resistant Staphylococcus aureus resulted in no significant increase in NVC-422 MICs, while ciprofloxacin MICs increased 256-fold for E. coli and 32-fold for P. aeruginosa and S. aureus. Mupirocin, fusidic acid, and retapamulin MICs for MRSA increased 64-, 256-, and 1...

A systematic review was performed to determine the effectiveness of different approaches for eradicating methicillin-resistant Staphylococcus aureus carriage. Twenty-three clinical trials were selected that evaluated oral antibiotics (7 trials), topically applied antibiotics (12 trials), or both (4 trials). Because of clinical heterogeneity, quantitative analysis of all studies was deemed to be...

BACKGROUND AND OBJECTIVES Staphylococcus aureus is a versatile organism causing mild to life threatening infections. The major threat of this organism is its multidrug resistance. The present study was carried out to investigate in - vitro activity of conventional antibiotics routinely prescribed for methicillin resistant S. aureus (MRSA) and methicillin sensitive S. aureus (MSSA) infections in...

OBJECTIVES The increase in resistance of methicillin resistant Staphylococcus aureus (MRSA) strains to vancomycin has been perceived as a formidable threat in the therapeutic fields. The present study investigated the vancomycin resistance traits of MRSA isolates [vancomycin resistant S. aureus (VRSA)] collected from burn patients. MATERIALS AND METHODS Twenty-nine of 40 isolates of Staphyloc...

BACKGROUND A livestock-associated clonal lineage (ST398) of methicillin-resistant Staphylococcus aureus (MRSA) has been identified causing colonization or infection in farm workers. The aim of the study was to analyze the prevalence of MRSA-ST398 colonization in pigs and in pig farmers in an area with a high pig population (Osona, Barcelona province, Catalonia, Spain). METHODS We performed a ...

INTRODUCTION Staphylococcus aureus produces a range of virulence factors such as toxic shock syndrome toxin-1. METHODS In this cross-sectional study of 345 clinical S. aureus isolates, the presence of the tst gene was assessed by polymerase chain reaction (PCR). RESULTS The study revealed 53/345 (15.4%) isolates were positive for the tst gene. The tst gene was present in 18.1% of methicilli...
