[Comparative evaluation of the results of antibiotic sensitivity testing using automated microbiological systems and...

A total of 1120 comparative estimations of antibiotic sensitivity of clinical gram positive and gram negative bacteria isolated from patients with surgical and urological infections were performed. The data for comparison were obtained with the use of microbiological systems MIC-2000 and MS-2 and the disk diffusion method. A high percentage of coincidence for both gram negative and gram positive organisms was observed. The frequency of total coincidence was higher for Enterobacteriaceae. The results of disk diffusion estimations more frequently coincided with the results obtained with the use of apparatus MIC-2000 as compared to the results provided by MS-2. The choice of the nutrient medium markedly influenced the coincidence level of the results obtained with the apparatus and control methods.
