Evaluation of the accuracy of various phenotypic tests to detect oxacillin resistance in coagulase-negative staphylococci.
In this study, we determined the accuracy of phenotypic tests (cefoxitin agar dilution, 30 microg-cefoxitin and 1 microg-oxacillin disks) to detect the oxacillin resistance/mecA gene among coagulase-negative staphylococci (CoNS) isolates. The presence of the mecA gene was detected by PCR technique (gold standard). A total of 176 CoNS isolates from blood of hospitalized patients were evaluated. ...
متن کاملClinical validation for oxacillin susceptibility testing of coagulase negative staphylococci.
Oxacillin susceptibility of coagulase negative staphylococci as assessed by conventional methods was confirmed by a modified Etest method, extended to detect heteroresistance. Verification of susceptibility was followed by successful treatment for six consecutive children with deep seated infections. Physicians' trust in such a validated method will contribute to the appropriate use of antibiot...
متن کاملEvaluation of latex agglutination test and oxacillin resistant screening agar base (ORSAB) medium for the detection of oxacillin resistant coagulase negative Staphylococci (ORCoNS)
Coagulase negative Staphylococci (CoNS) are recognized as an important cause of nosocomial infection, especially in neonates and patients with indwelling prosthetic devices. The CoNS resistance rate to oxacillin has been increasing. Therefore, rapid and accurate detection of oxacillin resistance is essential in order to determine the most appropriate antimicrobial therapy. This study aimed to p...
متن کاملexamining the relationship between fear of negative evaluation and communication strategies by iranian efl learners
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
Evaluation of oxacillin and cefoxitin disks for detection of resistance in coagulase negative staphylococci.
Coagulase-negative Staphylococcus spp. was considered nonpathogenic until the emergence of multiresistance and the demonstration of their participation as infectious agents. In Brazil, oxacillin resistance may be present in over 80% of isolates, and the Clinical and Laboratory Standards Institute standardized a disk-diffusion method to predict this resistance in Staphylococcus. The aim of this ...
