Abstract:
The main objectives of this study were to compare the
results obtained by different methods carried for detecting the
antimicrobial sensitivity testing (NCCLS table diameter method,
Stokes and Kirby-Bauer comparative methods) and to compare the
results when using two standard media (Muller-Hinton and
Diagnostic sensitivity agar).
Fifty organisms were isolated and identified to reach these
objectives. They were from two different sites, urine, and wounds.
The isolates were: Escherichia coli, Pseudomonas aeruginosa,
Klebsiella pneumoniae, Proteus vulgaris, Staphylococcus aureus
and Enterococcus faecalis.
Antimicrobial sensitivity testing was carried out for each
organism by the three methods on the two media. The results were
recorded and analyzed to detect the differences. According to the
statistical analysis, no differences were found to be between the
comparative methods Stokes and Kirby-Bauer, while a significant
difference was reported between them and NCCLS method. When
comparing the two media, no differences were noted, and the
.results were found to be similar
