Human infections involving microorganisms i.e. bacteria, fungi, viruses, cause serious infections in tropical and subtropical countries of the world. In recent years, a multidrug resistance microorganism is on rise due to indiscriminate use of commercial drugs (Gutmann et al., 1988; Mohanasundari et al., 2007). Staphylococcus aureus is a Gram positive cocci arranged in clusters and is ubiquitou...

A total of 15 of 101 (14.8%) nasal methicillin-resistant Staphylococcus aureus (MRSA) isolates exhibited mupirocin resistance (Mup(r)) compared with 1 of 154 (0.6%) methicillin-susceptible Staphylococcus aureus isolates. A total of 14 (93%) isolates exhibiting high-level Mup(r) belonged to a single clone. Horizontal plasmid transfer and transmission of Mup(r) strains contribute to a high incide...

Background: Nasal carriage of Staphylococcus aureus has a key role in the epidemiology and pathogenesis of infection. In this study we aimed to investigate the occurrence of the methicillin resistant Staphylococcus aureus (MRSA )and mecA gene among healthy primary school boys in north of Iran.Material and methods: This cross-sectional study was conducted from January 2017 to July 2017 in Sari l...

BACKGROUND The rapid emergence and spread of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has raised considerable public health concern in both developed and developing countries. The current study aimed to address the extent of this phenomenon in healthy preschool children of a developing country. MATERIALS AND METHODS We conducted a prospective study from April...

background and objectives: staphylococcus aureus is an important cause of nosocomial and community-acquired infections in every region of the world. clindamycin is one of the alternative agents used to treat s. aureus infections and accurate identification of clindamycin resistance is important to prevent therapeutic failure. unfortunately, inducible clindamycin resistance is not detected by st...

Cibacron blue F3GA (CB) was found to reduce the MIC of oxacillin for methicillin-resistant Staphylococcus aureus (MRSA). This effect was not observed with methicillin-susceptible S. aureus. CB alters the resistance level of MRSA through a factor(s) other than mecA-related products, major autolysins, or femAB products. The exact target(s) of CB in causing the effect is unknown.

With its remarkable armamentarium of resistance and virulence factors, Staphylococcus aureus has emerged as a dominant pathogen causing pneumonia of all classifications. Rates of methicillin resistance are increasing as clinicians struggle to find ways to prevent the acquisition of methicillin-resistant Staphylococcus aureus (MRSA) and to effectively treat MRSA pneumonia. Community-associated M...

ESR has undertaken national surveillance of methicillin-resistant Staphylococcus aureus (MRSA) since MRSA was first identified in New Zealand in 1975. For the next decade, MRSA remained uncommon in New Zealand, with a maximum of 13 people identified with MRSA in any one year. In a 1982 national survey of antimicrobial resistance among S. aureus, just one (0.05%) of 2077 isolates included in the...

Successful empirical therapy of Staphylococcus aureus infections requires the ability to predict methicillin resistance. Our aim was to identify predictors of methicillin resistance in community-onset (CO) invasive S. aureus infections. Sixteen hospitals across Korea participated in this study from May to December 2012. We prospectively included cases of S. aureus infection in which S. aureus w...

BACKGROUND Methicillin-Resistant Staphylococcus aureus (MRSA) is a major pathogen in the hospital and community settings. Rapid methods to diagnose S. aureus infections are sought by many researchers worldwide. The current study aimed to utilize a phenotypic method of turanose fermentation to identify methicillin-susceptible and resistant S. aureus. OBJECTIVES The current study aimed to assay...
