BACKGROUND Staphylococcus aureus is the most commonly isolated organism from the different clinical samples in hospital. The emergence and dissemination of methicillin resistant Staphylococcus aureus (MRSA) and growing resistance to non-beta-lactam antibiotics is making treatment of infections due to this organism increasingly difficult. METHODS This study was conducted to determine the frequ...
Antimicrobial resistance is one of the most urgent problems in medicine nowadays. The purpose of the study was to investigate the microorganisms resistant to first-line antimicrobials, including gram-positive cocci, particularly the methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococci, the major agents of nosocomial infections. Owing to the multi-resistance of these ...
conclusions frequency of s. epidermidis was significantly lower, compared to other studies. presence rate of meca and susceptibility to linezolid and vancomycin did not show significant differences with other investigations, while resistant to trimethoprim-sulfamethoxazole was significantly lower compared to other investigations, and resistance to tetracycline was significantly higher in compar...
Background: Antibiotics called macrolide, lincosamide and streptogramin B (MLSB) are being used to treat staphylococci infections. Multiple pathways that impart resistance to MLSB antibiotics have been confirmed to cause clinical failure. The present work aimed to determine the frequency of constitutive and inducible clindamycin resistant among coagulase-negative staphylococci (CoNS) isolates o...
BACKGROUND Staphylococcus aureus is a pathogen that causes food poisoning and community-associated infection with antibiotic resistance. This species is an indigenous intestinal microbe found in infants and not found in adult intestine. The relatively small genome size and rapid evolution of antibiotic resistance genes in the species have been drawing an increasing attention in public health. T...
INTRODUCTION Community-acquired methicillin-resistant Staphylococcus aureus infections are a common, serious problem in pediatrics. OBJETIVE To describe antibiotic resistance in community-acquired Staphylococcus aureus (SA) bacteremias. To compare the characteristics of SA bacteremias in terms of methicillin resistance. MATERIALS AND METHODS Prospective cohort enrolled between January 2010 ...
Background and Aims: Staphylococcus aureus is one of the important pathogens around the world. The present investigation was carried out to study the distribution of Staphylococcal Cassette Chromosome Mec (SCCmec) types and antibiotic resistance properties in methicillin-resistant Staphylococcus aureus isolated from Isfahan hospitals. Materials and Methods: A total of 250 clinical specimens ...
Chromosomal BamHI DNA fragments containing both the mecA gene encoding the penicillin-binding protein responsible for methicillin resistance and the aadD gene encoding 4',4"-adenylyltransferase responsible for tobramycin resistance were cloned from three methicillin- and tobramycin-resistant strains of Staphylococcus aureus and one strain of Staphylococcus epidermidis. Physical maps of the frag...
objective: methicillin-resistant staphylococcus aureus is a major cause of nosocomial and community-acquired infections. aminoglycosides are potent bactericidal agents that are often used in combination with either a β-lactam or a glycopeptide, especially in the treatment of staphylococcal endocarditis. the main mechanism of aminoglycoside resistance in staphylococci is drug inactivation by cel...
We demonstrated the marked emergence of resistance to ciprofloxacin among Staphylococcus arueus strains isolated at the Ann Arbor Veterans Administration Medical Center. All S. aureus isolates tested from 1984 to 1985 were susceptible, whereas 55.1% of methicillin-resistant and 2.5% of methicillin-susceptible strains from 1989 had high-level resistance to ciprofloxacin.
