Detection of Methicillin-Resistant Staphylococcus Aureus by Phenotypical and Molecular Methods among Clinical Isolates
Abstract Background and Objective: Increasing prevalence of methicillin resistant Staphylococcus aureus strains (MRSA) with their multidrug resistance potential causes difficulties in the treatment of infections due to these bacteria. Hence, the detection and determination of the frequency of MRSA strains via phenotypical and molecular methods is necessary in different parts of the county. ...
متن کاملCharacterization 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 کاملPhenotypic Changes of Oxacillin Resistance in Methicillin-resistant Staphylococcus aureus Strains by Successive Passaging
Background and purpose: Rotational use of antibiotics can decrease antibiotic resistance in Staphylococcus aureus strains. The present study aimed to evaluate the alteration of oxacillin resistance in methicillin-resistant Staphylococcus aureus (MRSA) strain carrying SCCmec III cassette in long-term evolutionary experiments in an antibiotic-free medium. Materials and methods: In a cross-sectio...
متن کاملSynergy between oxacillin and manuka honey sensitizes methicillin-resistant Staphylococcus aureus to oxacillin.
OBJECTIVES Honey is an ancient wound remedy that has recently been introduced into modern clinical practice in developed countries. Manuka honey inhibits growth of methicillin-resistant Staphylococcus aureus (MRSA) by preventing cell division. In Gram-negative bacteria a synergistic interaction between honey and antibiotics has been suggested. We aimed to determine the effect of manuka honey on...
متن کاملImmunogenicity analysis of Staphylococcus aureus clumping factor A genetic variants.
The staphylococcal adhesin clumping factor A (ClfA) has a variant amino acid sequence, generating the potential for alterations in epitope structure and immunogenicity of this vaccine candidate. We demonstrated for two recombinant ClfA(40-531) (a slightly truncated version of the fibrinogen-binding domain of ClfA containing amino acids 40 to 531) genetic variants that strain-specific epitopes a...
