Bioassay Guided Fractionation of an Anti-Methicillin-Resistant Staphylococcus aureus Flavonoid From Bromus inermis Leyss Inflorescences
BACKGROUND Plants are considered as promising sources of new antibacterial agents as well as bioassay guided fractionation. OBJECTIVES In the present work, the antibacterial properties, especially against methicillin-resistant Staphylococcus aureus (MRSA), of Bromus inermis inflorescence was studied, using the bioassay guided fractionation as well as the bio-autographic method. MATERIALS AN...

conclusions as a result of the full range uv-vis scanning of the responsible band in the hptlc experiments (200-700 nm), the flavonoid was the most imaginable natural compound. results through the bioassay guided fractionation method, the greatest antibacterial activities were related to the n-hexane extract. it was also revealed that the effective anti-mrsa agent of the assessed plant was a re...
متن کاملMethicillin Resistant Staphylococcus aureus
Etiology Staphylococcus aureus is a Gram positive, coagulase positive coccus in the family Staphylococcaceae. Methicillin-resistant S. aureus (MRSA) strains are resistant to methicillin and essentially all other beta-lactam antibiotics. MRSA isolates are genetically heterogeneous. 1 Some strains, which are called epidemic strains; are more prevalent and can spread within or between hospitals an...
متن کاملMethicillin Resistant Staphylococcus aureus
Staphylococcus aureus is an opportunistic pathogen often carried asymptomatically on the human body. Methicillin-resistant S. aureus (MRSA) strains have acquired a gene that makes them resistant to all beta-lactam antibiotics. Hospital-associated strains of this organism are serious nosocomial pathogens that have become resistant to most common antibiotics, and treatment can be challenging. Com...

received much attention over the past 30 years because of its increasing incidence and the morbidity and excess hospital stay length associated with MRSA infection. Th e current controversy about the eff ectiveness of control measures, notably screening, derives from the confl icting results of available studies, lack of well-designed controlled studies, and concomitant use of several intervent...
