Abstract Background and Objective: Due to the continuous increase of multidrug-resistant Acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. In this study, the validity of disk diffusion and E-test methods was assessed b...
In June 1987, the Antimicrobial Susceptibility Testing Subcommittee of the National Committee for Clinical Laboratory Standards (NCCLS) established a fastidious-organism working group expressly for the purpose of addressing issues related to in vitro susceptibility tests with aerobic or microaerophilic bacteria that do not grow well on unsupplemented Mueller-Hinton (MH) media. The fastidious-or...
Background and Objective: Pseudomonas aeruginosa has become a frequent cause of nosocomial infections, particularly in intensive care units (ICUs). Many reports have documented high rates of resistance in this species to commonly-used broad-spectrum antibiotics. The aim of this study was to assess the in vitro activity of some a...
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...
21 The agar dilution method has been standardized by the CLSI for the susceptibility testing of 22 Campylobacter species, and according to these standards, the disk diffusion method should only 23 be used for the screening of macrolide and ciprofloxacin resistance. Nevertheless, the disk 24 diffusion test is currently widely used, since it is easy to perform in clinical microbiology 25 laborato...
Background: Background: Today, due to the increased use of antibiotics and spread of resistant strains, using natural compounds as an alternative to synthetic compounds, with fewer side effects, has been widely importance. The aim of this study was to investigate the antimicrobial activity of ethanolic extracts of seven medicinal herb include; green tea (Camellia sinensis), thyme Khorasani (Th...
The emergence of infections caused by multidrug-resistant Pseudomonas aeruginosa and Acinetobacter spp. has necessitated the search for alternative parenteral agents such as the polymyxins. The National Committee for Clinical Laboratory Standards (NCCLS) documents do not currently provide interpretative criteria for the testing of the polymyxins, colistin and polymyxin B. Therefore, an evaluati...
The incidence rate for scarlet fever in South Korea is rising. During 2008-2015, we collected group A Streptococcus isolates and performed emm and exotoxin genotyping and disk-diffusion antimicrobial tests. Scarlet fever in South Korea was most closely associated with emm types emm4, emm28, emm1, and emm3. In 2015, tetracycline resistance started increasing.
A total of 24 strains of the Mycobacterium fortuitum complex were tested for susceptibility to antimicrobial agents by the disk diffusion and agar dilution techniques. By comparing zones of inhibition obtained with the disk diffusion technique with results of minimal inhibitory concentration determinations, it was shown that disk diffusion results could predict in vitro susceptibility to select...
