To determine appropriate mupirocin susceptibility testing interpretive criteria, 177 staphylococci were tested by agar dilution, disk diffusion, and E test. E test was found to be a reliable method for determining susceptibility of staphylococci to mupirocin. The agar dilution and disk diffusion results were plotted on a scattergram, and error rates were calculated. No errors were found with su...

background and aims. enterococci are gram-positive cocci that often occur in pairs (diplococci) or short chains. beside developing high level of antibiotic resistance, these bacteria can cause wide range of disease in human, thus to help provide an effective treatment for infections caused by this genus, this study was conceived to provide information on enterococcus faecalis antibiotic resista...

objective(s) the aim of this study was to investigate the presence of per-1-type esbls in drug resistant pseudomonas aeruginosa isolates. materials and methods during one-year period (2008-2009), following isolation and identification of 56 p. aeruginosa, the e-test method was performed for determination of minimal inhibitory concentration of ceftazidim. the isolates that they had mic≥16 µg/ml ...

The agar dilution method has been standardized by the CLSI for the susceptibility testing of Campylobacter species, and according to these standards, the disk diffusion method should be used only in screening for macrolide and ciprofloxacin resistance. Nevertheless, the disk diffusion test is currently widely used, since it is easy to perform in clinical microbiology laboratories. In this study...

Nevertheless, the disk 24 diffusion test is currently widely used, since it is easy to perform in clinical microbiology 25 laborato...

A 5-h broth disk test, read visually for growth or no growth to determine resistance of coagulase-negative staphylococci to 1.6 micrograms of novobiocin per ml, was evaluated as a rapid test for the presumptive identification of Staphylococcus saprophyticus. The correlation with an overnight disk diffusion test was 100%.

In this paper we report on an experimental evaluation of phenotypic and molecular methods as means for the detection of oxacillin resistance in members of the Staphylococcus sciuri group. A total of 109 S. sciuri group member isolates (92 S. sciuri isolates, 9 S. lentus isolates, and 8 S. vitulinus isolates) were tested by the disk diffusion method, the agar dilution method, the oxacillin salt-...

Background and Aim:  Streptococcus sanguinis (S. sanguinis) is one of the effective bacteria in the formation of caries and periodontal diseases which are caused by dental plaque. Currently, the use of natural honey (NH) is considered as a method of reducing S. sanguinis and S. mutans in saliva, which results in reducing the dental plaque. The purpose of this study was to evaluate the effects o...
