abstract background and aim: oral infections and dental caries are considered as two serious public health problems, which inflict a costly burden on health care services worldwide, especially in the developing countries. the aim of this study was to evaluate the antibacterial activity of iranian licorice aqueous root extract on lactobacillus acidophilus in comparison with chlorhexidine. materi...
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 by their comparison with the re...
Two hundred and fifty tracheal aspirates were subjected to direct antimicrobial susceptibility testing by disk diffusion, Etest and inoculation on antibiotic-enriched MacConkey agar plates. Results were compared with those obtained using an automated system on microorganisms recovered from standard quantitative culture. A total of 255 microorganisms were isolated from 194 positive samples by th...
Background and purpose: Garlic and cinnamon extracts, like fluoride varnish, play a role in caries control due to their antimicrobial effect and controlling demineralization. This analytical laboratory study was conducted in 2021 to investigate the antimicrobial effect of garlic and cinnamon extracts compared with fluoride varnish in controlling the infection of oral Lactobacillus acidophilus a...
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...
Background and Objective: Pseudomonas aeruginosa is the most common pathogen causing nosocomial infections. The aim of this study was to determine the antimicrobial susceptibility pattern and prevalence of ESBLs in clinical and environmental isolates of P. aeruginosa by phenotypic and genotypic techniques. Materials and Methods: In this descriptive study, a total of 100 P. aeruginosa strains is...
Studies were conducted to compare and evaluate antimicrobial susceptibility test results for enterococci obtained by six national committee disk diffusion procedures. Variations in the incidence of isolates in resistance categories and errors were associated with the use of ciprofloxacin, gentamicin, nitrofurantoin, rifampin, and teicoplanin in a number of committee procedures. Results indicate...
Standard reference strains of Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa were suspended in sterile deionized water and tested daily via disk agar diffusion for their antimicrobial susceptibilities. Inocula of E. coli and P. aeruginosa yielded acceptable results for up to 32 days; however, results on S. aureus were unacceptable due to loss of viability of the organism in...
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...
