The present study was conducted to isolate and characterize the molecular epidemiology of the methicillin-resistant staphylococci in the general university environment, where all five locations; the library, restrooms, canteens, computer rooms and outdoor surfaces, are in common use by a large population of students. We used Mannitol Salt Agar (MSA) supplemented with 4 μg/ml of oxacillin to scr...

Background: Blood stream infection is one of the main causes of morbidity and mortality in patients with cancer. The purpose of this study was to evaluate the prevalence of aerobic and anaerobic-bacteremia in hospital inpatients with cancer and to determine the antibiotic resistance profile in isolated organisms in Kerman, southeast Iran. Methods: Total of 240 blood cultures from 136 patients w...

The in vitro activity of DX-619, a new des-F(6)-quinolone, was tested against staphylococci and compared to those of other antimicrobials. DX-619 had the lowest MIC ranges/MIC(50)s/MIC(90)s (microg/ml) against 131 Staphylococcus aureus strains (</=0.002 to 2.0/0.06/0.5) and 128 coagulase-negative staphylococci (0.004 to 0.25/0.016/0.125). Among strains tested, 76 S. aureus strains and 51 coagul...

Vitek 2 (bioMérieux, Inc., Durham, NC) is a widely used commercial antimicrobial susceptibility testing system. We compared MIC results obtained by Vitek 2 to those obtained by the Clinical and Laboratory Standards Institute (CLSI) broth microdilution (BMD) reference method for 134 staphylococcal and 84 enterococcal clinical isolates. Nineteen agents were evaluated, including all those availabl...

aims: it is very important to detect the coagulase-negative staphylococci, which produce the hospital infections. being one of the most expensive and time-consuming stages before the polymerase chain reaction (pcr), dna extraction is one of the primary stages of pcr. then, it should be noticed that the elimination of the stage might save time and costs. the aim of this study was to compare two ...

Four commercially available rapid agglutination tests for the identification of Staphylococcus aureus were compared with the tube coagulase test for the identification of 300 methicillin-resistant isolates of staphylococci. Isolates tested included 207 methicillin-resistant S. aureus and 93 coagulase-negative staphylococci, collected from five medical centers. Strain variability was documented ...
