Purification and characterization of aminoglycoside-modifying enzymes from Staphylococcus aureus and Staphylococcus epidermidis.
Several strains of Staphylococcus aureus and Staphylococcus epidermidis, exhibiting characteristic resistance patterns to aminoglycoside antibiotics, were examined. The aminoglycoside-modifying enzymes from these strains were purified by DEAE-Sephadex A-50 chromatography, affinity chromatography, and Sephadex G-100 gel filtration. Three enzymes, a 3'-phosphotransferase III (molecular weight, 31...
متن کاملSynergistic Effects of Gold Nanoparticles Mixed with Gentamicin, Erythromycin, Clindamycin, Bacitracin, and Polymyxin B against Staphylococcus aureus, Staphylococcus saprophyticus, Staphylococcus epidermidis, Enterococcus faecium and Enterococcus fae
Background and Objective: The majority of bacterial infections are now treatable using different classes of antibiotics. However, the world has faced a challenge called antimicrobial resistance that will diminish most antibiotics' beneficial impacts. A valuable strategy to prevent this adverse phenomenon is to increase the antibacterial effects of antibiotics using various materials as antibiot...
متن کاملاثر ضدمیکروبی بخش هوایی گلدار عروس سنگ طلایی (.dionysia revoluta boiss) علیه استافیلوکوک کوآگولاز مثبت (staphylococcus aureus) و استافیلوکوک های کوآگولاز منفی (staphylococcus epidermidis, staphylococcus saprophyticus)
dionysia revoluta boiss یکی از گیاهان متعلق به تیره primulaceae می باشد که پراکندگی نسبتا محدودی در جنوب ایران دارد. با توجه به این که اسانس حاصل از بخش هوایی این گیاه اثر قابل توجهی علیه بعضی باکتری های بیماری زا نشان داده است. در این پروژه اثر ضدمیکروبی عصاره تام متانولی و کلرفرمی و آبی حاصل از بخش هوایی گلدار گیاه را بر استافیلوکوکوس اورئوس و استافیلوکوکوس اپیدرمیدیس و استافیلوکوکوس ساپروفیت...
Cloning, Expression, and Purification of Recombinant Lysostaphin From Staphylococcus simulans
BACKGROUND Staphylococcus aureus is one of the most common causes of nosocomial infections and its resistance to antibiotics is a global concern. Lysostaphin is an antimicrobial agent belonging to a major class of antimicrobial peptides and proteins known as the bacteriocins. It exhibits a high degree of anti-staphylococcal bacteriolytic activity. OBJECTIVES In this study, high level of recom...
متن کاملHomology of mecA gene in methicillin-resistant Staphylococcus haemolyticus and Staphylococcus simulans to that of Staphylococcus aureus.
A penicillin-binding protein of molecular weight 76,000 inducible by beta-lactams was detected in methicillin-resistant Staphylococcus haemolyticus and Staphylococcus simulans. DNA from these strains hybridized to the mecA gene from Staphylococcus aureus; however, the chromosomal HindIII fragments containing the mecA genes were 3.4 kilobases in S. haemolyticus and 4.3 kilobases in S. simulans.
