conclusions the rate of imlsb in s. aureus isolates is relatively high in the northwest iran. since isolates with inducible resistance may mutate and change to constitutive resistance, to prevent clinical treatment failure, d-test should be performed along with routine antibiotic susceptibility tests. in this study, ermc gene was the predominant genetic determinant for the expression of mlsb re...

Background. Global concerns have been raised due to upward trend of Vancomycin Intermediate Staphylococcus aureus (VISA) and Vancomycin Resistant Staphylococcus aureus (VRSA) reports which mean casting doubt on the absolute effectiveness of the last line of antibiotic treatment for S. aureus, vancomycin. Hence, epidemiological evaluation can improve global health care policies. Methodology. 171...

This study assessed the in vitro activities of ceftaroline and five comparator agents against a collection of Staphylococcus aureus isolates. Ceftaroline demonstrated potent activity against community-associated methicillin-resistant S. aureus (CA-MRSA) isolates and showed bactericidal activity against vancomycin-intermediate S. aureus (VISA), vancomycin-resistant S. aureus (VRSA), heteroresist...

background quorum sensing is a microbial cell-to-cell communication process. quorum sensing bacteria produce and release extracellular messenger molecules called autoinducers. gram-positive and gram-negative, homoserine lactones, and oligopeptides are autoinducers used to communicate and regulate gene expression. objectives the goal of this study was to assess the impact of subinhibitory concen...

Invasive disease following methicillin-resistant Staphylococcus aureus (MRSA) detection is common, regardless of whether initial detection involves colonization or infection. We assessed the genetic relatedness of isolates obtained > or =2 weeks apart representing either repeated infections or colonization-infection sets to determine if infections are likely to be caused by previously harbored ...
