b a ckground: s taphylococcus aureus (s. aureus) has remained always an important pathogen of common infections acquired in community and as  well as serious nosocomial infections. with advent of penicillins and cephalosporins, infections could be effectively treated, but with the global emergence of methicillin resistant staphylococcus aureus strains (mrsa) physicians were  again left  with li...

OBJECTIVE To examine the recovered strains phenotypically, by conventional methods and genotypically by polymerase chain reaction (PCR), for direct detection of Staphylococcus aureus (S. aureus) 16S ribosomal Ribonucleic Acid (rRNA) gene (which serves as an internal control) and mecA gene. Secondly, introduce multiplex PCR targeting at the same time S. aureus 16S rRNA, Panton-Valentine Leucocid...

background: staphylococcus aureus is a major human pathogen. due to high prevalence of s. aureus infections and increasing resistance to antibiotics, physicians have been facing problems in choosing the appropriate empirical antibiotic therapy for such infections. objectives: the aim of this study was to determine the pattern of antibiotic resistance in s. aureus clinical isolates of mashhad qu...

background: ventilator-associated pneumonia (vap) is a type of nosocomial pneumonia which develops more than 48 hours after endotracheal intubation. early recognition and treatment of vap is important, since timely and appropriate management can be lifesaving. objectives: this study aimed to determine the antimicrobial susceptibility pattern of microorganisms causing vap in the intensive care u...

INTRODUCTION Staphylococcus aureus colonisation/infection is common in children with atopic dermatitis (AD). MATERIALS AND METHODS We evaluated the nasal and body swabs of Chinese children with moderate-to-severe AD as assessed using SCORing-Atopic-Dermatitis (SCORAD) score. Swabs were taken from the right nostril, 5 flexural sites (anterior neck, antecubital fossae and popliteal fossae) and ...

We modeled estimates of the incidence, deaths, and direct medical costs of Staphylococcus aureus infections in hospitalized patients in the New York City metropolitan area in 1995 by using hospital discharge data collected by the New York State Department of Health and standard sources for the costs of health care. We also examined the relative impact of methicillin-resistant versus -sensitive ...

71 samples of milk and dairy products were collected from 18 cities throughout Iran. 93 strains of lactic acid bacteria (LAB) were isolated and assayed against four opportunistic patho gens including E. coli, proteus and klebsiella as gram-negative and S. aureus as a gram-positive organism. All indicators (organisms) were hospital strains. Among isolated bacteria, lactobacilli (37 isolates)...

Staphylococcus aureus (including Methicillin-resistant S. aureus) and coagulase negative Staphylococcus spp (including methicillin-resistant coagulase negative) permanently or transiently colonize humans and act as sources of complicated skin and soft tissue infections, bacteraemia and infective endocarditis. They also cause chronic infection of indwelling medical devices. Treatment of these in...

Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), is an important human pathogen that produces a variety of toxins and causes a wide range of infections, including soft-tissue infections, bacteremia, and staphylococcal food poisoning. A loop-mediated isothermal amplification (LAMP) assay targeting the arcC gene of S. aureus was developed and evaluated with 119 S. aureus a...

AIM This study was conducted to determine the occurrence of methicillin-sensitive and Staphylococcus aureus (MSSA) methicillin-resistant S. aureus (MRSA) from bovine mastitis and to characterize them with respect to antibiotic resistance gene mecA. MATERIALS AND METHODS A total of 160 mastitic milk samples were screened for the presence of S. aureus. The presumptive positive isolates were con...
