Characterization of a catalase-negative methicillin-resistant Staphylococcus aureus strain.
We describe an unusual clinical strain of catalase-negative methicillin-resistant Staphylococcus aureus sensu stricto. Sequence analysis of its catalase gene showed 99.60% identities to the catalase genes of the reference strains. A 5-base deletion, however, led to a shift of the nucleotide reading frame and a loss of the enzymatic activity.
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...
متن کاملMethicillin Resistant Staphylococcus aureus
Staphylococcus aureus is an opportunistic pathogen often carried asymptomatically on the human body. Methicillin-resistant S. aureus (MRSA) includes those strains that have acquired a gene giving them resistance to methicillin and essentially all other beta-lactam antibiotics. MRSA was first reported in 1961, soon after methicillin was introduced into human medicine to treat penicillinresistant...
