Altered muropeptide composition in Staphylococcus aureus strains with an inactivated femA locus

Vancomycin Resistance in Staphylococcus aureus Strains

Antibiotic Resistance and Detection of femA Gene in Staphylococcus Aureus Isolates from Raw Milk

ABSTRACT         Background and Objective: Antibiotic-resistant Staphylococcus aureus strains have become a problem in treatment of infections caused by S. aureus. This study aimed to evaluate antibiotic resistance in S. aureus isolates from raw milk and detect femA gene in these isolates, as a confirmatory test for identification of S. aureus species. ...

Staphylococcus Aureus Carriage in Patients with Psoriasis

Background: The aggravating role of Staphylococcus aureus is well known in atopic dermatitis but has not yet been proven in psoriasis. The role of Staphylococcus aureus superantigens is emphasized in the initiation, maintenance and complications of psoriasis. We investigated the frequency of nasal, axillary, and perineal carriage of Staphylococcus aureus (SA) in patients with psoriasis and its ...

The Spread of Beta Lactam Antibiotic-Resistant Staphylococcus aureus and Staphylococcus epidermidis Strains in Hospital

Bachground and objectives: Hospital surfaces can serve as reservoirs of potential pathogen bacteria. Staff hands are the most important source of transmission in hospital. The prevalence of β–lactamase producer bacteria in staff hands and hospital surfaces, increase antibiotic resistance nosocomial infection. The aim of this study was to survey the spread of beta-lactam resistance St...

Staphylococcus aureus β-toxin production is common in strains with the β-toxin gene inactivated by bacteriophage.

BACKGROUND Staphylococcus aureus causes life-threatening infections, including infective endocarditis, sepsis, and pneumonia. β-toxin is a sphingomyelinase encoded for by virtually all S. aureus strains and exhibits human immune cell cytotoxicity. The toxin enhances S. aureus phenol-soluble modulin activity, and its activity is enhanced by superantigens. The bacteriophage φSa3 inserts into the ...
