In this case report, we describe the first instance of septicemia caused by an obligately anaerobic Staphylococcus aureus in a human. A 45-year-old man presented with septicemia, septic arthritis, and multiple pulmonary abscesses, which were caused by an obligately anaerobic S. aureus. The clinical and microbiological features that led to the diagnosis are discussed. Genotyping cannot at presen...

Wound infection caused by Staphylococcus aureus (S. aureus) is a critical clinical problem due to long hospitalization times, significant morbidity and mortality, as well as considerable medical resource consumption. With the emergence of methicillin-resistant S. aureus (MRSA) strains, current antibiotic treatments are becoming ineffective in combatting S. aureus infection. Thus, a novel therap...

Of 500 hospital-onset Staphylococcus aureus bacteremia events (58% methicillin-susceptible S. aureus [MSSA]; 42% methicillin-resistant S. aureus [MRSA]), we found no significant differences in S. aureus bacteremia rates between medium-sized and large hospitals. However, the proportion of S. aureus bacteremia caused by MSSA was greater in medium-sized hospitals and did not correlate with MRSA ba...

background: the aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (mrsa) and methicillin-susceptible (mssa) staphylococcus aureus. methods: in total, 209 s. aureus isolates were collected. the antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of clinica...

materials and methods this definitive and cross-sectional study was conducted in tehran, iran. a total of 15 s. aureus isolates were collected from wound samples with sterile swabs and were identified by the conventional diagnostic tests. the antibiotic susceptibility pattern was performed according to the clinical and laboratory standards institute (clsi, 2012) protocol. the meca gene, staphyl...

b a ckground : in fact the biofilms are composed of bacterial cells living inmulticellular structures such as tissues and organs embedded within a self-produced matrix of extracellular polymeric substance (eps). ability to attach and biofilm formation are the most important virulence factors staphylococcus aureus isolates. the aims of this study were to detect intracellular adhesion (ica) locus...

The effect of the addition of lactoferrin on Staphylococcus aureus to Minas frescal cheese was evaluated. Three cheeses were made: control (S. aureus), Lf-2% (2% lactoferrin + S. aureus) and Lf-4% (4% lactoferrin + S. aureus). Cheeses were packaged and S. aureus populations were determined on days 1, 8, 15, 22 and 29 of storage at 6 degrees C. The experiment was repeated three times. S. aureus ...

BACKGROUND The USA300 methicillin resistant Staphylococcus aureus (MRSA) genetic background has rapidly emerged as the predominant cause of community-associated S. aureus infections in the U.S. However, epidemiologic characteristics of S. aureus household transmission are poorly understood. METHODS We performed a cross-sectional study of adults and children with S. aureus skin infections and ...

BACKGROUND Staphylococcus aureus nasal carriage is a major risk factor for nosocomial S. aureus infection. Studies show that intranasal mupirocin can prevent nosocomial surgical site infections. No data are available on the efficacy of mupirocin in nonsurgical patients. OBJECTIVE To assess the efficacy of mupirocin prophylaxis in preventing nosocomial S. aureus infections in nonsurgical patie...

BACKGROUND To describe the incidence, clinical characteristics, and outcomes of Staphylococcus aureus bacteremia after liver transplantation and investigate the drug resistance of S. aureus to frequently used antibiotics to provide evidence for clinical prevention and therapy. MATERIALS AND METHODS In a double-center retrospective study, blood cultures positive for S. aureus were obtained fro...
