Staphylococcus aureus is notorious for its ability to become resistant to antibiotics. Infections that are caused by antibiotic-resistant strains often occur in epidemic waves that are initiated by one or a few successful clones. Methicillin-resistant S. aureus (MRSA) features prominently in these ep...
aureus (VRSA) are now used, when 8-16 µg/ml or > 32 µg/ml of vancomycin respectively, is needed to inhibit staph growth during antibiotic susceptibility test (7). VISA and VRSA are not more powerful than other staphylococci, but they should be recognised as such, otherwise the ...
aureus was first isolated in the early 1960s, shortly after methicillin came into wide use as an antibiotic. Today methicillin is no longer used, but the strain of MRSA to which it gave rise is commonly found on the skin, in the nose, and in the blood and urine of humans. An ...
What is MRSA?MRSA (methicillin-resistant Staphylococcus aureus) is a strain of staph bacteria that can cause infection. Usually, antibiotics are used to kill bacteria. MRSA bacteria are resistant to the common antibiotics used to treat Staph infections. This makes MRSA hard to treat. MRSA most ...
aureus is established intracellularly for 12 h, the bacteria are less sensitive to antibiotics capable of eukaryotic cell penetration (statistically significant). These antibiotic sensitivity changes could be due in part to the observed structural changes. This leads to the rejection of our null ...
Conventional treatment of bacterial UTIs should be performed by evaluating patterns of antibiotic sensitivity and resistance, through the culture of urine samples. Commonly used antibiotics include amoxicillin-clavulanate, ciprofloxacin, cephalosporin, nitrofurantoin, trimethoprim-sulfamethoxazole, among others; how...
More than 40% of Staphylococcus aureus strains isolated in hospitals are methicillin-resistant, thus posing daily problems regarding therapy. The treatment of these infections is principally based on glycopeptides. The need or not to combine them, first-line or second-line, with another antibiotic,...

whether resistant strains are present in the infection. Drug-resistant strains require cautious treatment approaches, which in many instances involves the antibiotic vancomycin, to which most antibiotic-resistant strains remain susceptible. For non-resistant strains ofS. aureus,penicillinis generally used. ...
We describe a collection of antibiotic-activated Staphylococcus aureus promoter-lux reporter strains that can be used to discriminate among antibiotic classes on the basis of their light production response profile. We screened over 400 culture supernata
