Chronic nasal carriage of the bacterium Staphylococcus aureus in patients with the autoimmune disease granulomatosis with polyangiitis (GPA) is a risk factor for disease relapse. To date, it was neither known whether GPA patients show similar humoral immune responses to S. aureus as healthy carriers, nor whether specific S. aureus types are associated with GPA. Therefore, this study was aimed a...
objective(s) staphylococcus aureus is both a successful human commensal and a major pathogen. in this study we investigated the genetic diversity of 26 s. aureus isolates recovered from human skin and urinary tract infections. materials and methods typing procedure for the studied s. aureus isolates was performed based on pcr amplification of the aroa gene, which encodes the enzyme 5-enolpyruvy...
Background & Aims of the Study: Methicillin-resistant staphylococcus aureus (MRSA) is considered as a major pathogen in public health concern. The objectives of this study were to firstly determine antibiotic sensitivity among Staphylococcus aureus isolated from traditional Iranian white cheese during 2015 from Hamedan province of Iran; and secondly to estimate the presence of ...
introduction: staphylococcus aureus (s. aureus) is a bacterium found on the skin and hair of people and animals. s. aureus could product some extracellular protein. materials and methods: one hundred and fifty s. aureus isolates that were collected from different resources were screened for the meca, tst-1, eta and etb genes by pcr. 50 isolates were selected from human staphylococcal isolates a...
Mechanisms of protective immunity to Staphylococcus aureus infection in humans remain elusive. While the importance of cellular immunity has been shown in mice, T cell responses in humans have not been characterised. Using a murine model of recurrent S. aureus peritonitis, we demonstrated that prior exposure to S. aureus enhanced IFNγ responses upon subsequent infection, while adoptive transfer...
The rate of nosocomial bacteremia due to Staphylococcus aureus has increased over the past decade, but trends in community-acquired S. aureus bacteremia are less certain. This hospital-based observational study compares nosocomial and community-acquired S. aureus bacteremias during 1980-1983 and 1990-1993. The rate of nosocomial S. aureus bacteremia increased from 0.75 to 2.80 cases per 1,000 d...
BACKGROUND AND OBJECTIVES Staphylococcus aureus is a leading cause of infection in patients with ESRD. Clinical and economic outcomes associated with S. aureus bacteremia and other S. aureus infections in patients with ESRD were examined. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Laboratory, clinical, and hospital billing data from a randomized trial of 3359 hemodialysis-dependent patient...
BACKGROUND Pulmonary Staphylococcus aureus (S. aureus) infections occur early in a high percentage of cystic fibrosis (CF) patients and it is believed that these infections facilitate further colonization of CF lungs with Pseudomonas aeruginosa (P. aeruginosa). Previous studies demonstrated a marked reduction of sphingosine in tracheal and bronchial epithelial cells in CF compared to wild type ...
the prevalence of methicillin resistant staphylococcus aureus (mrsa) and methicillin sensitivestaphylococcus aureus (mssa) carriage among poultry and poultry farmers in malaysia is largely unknown.in the current investigation, chickens and chicken farmers from 30 chicken farms were screened for mrsaand s. aureus carriage. the genetic characteristics of the isolates were determined through multi...
removing the bacteria, including enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.we aimed to compare the antibacterial activity of chlorhexidine with two natural drugs. the antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and aloe vera gel on e. faecalis were compared using three methods: disk diff...
