24 lut 2023 · Disk diffusion is often the first AST method commercially available for testing bacteria against new antimicrobial agents. It is an accurate method, although with the downside of not providing an MIC, which is crucial for dose optimization in certain situations.
1 gru 2009 · Some methods provide quantitative results (eg, minimum inhibitory concentration), and all provide qualitative assessments using the categories susceptible, intermediate, or resistant. In general, current testing methods provide accurate detection of common antimicrobial resistance mechanisms.
17 maj 2020 · The performance of antimicrobial susceptibility testing (AST) of bacterial pathogens is an important task to determine susceptibility to the antimicrobial agents and to detect possible drug resistance in clinical microbiology laboratories.
21 gru 2019 · For the first time, a rapid method was proposed to determine the susceptibility of Escherichia coli cells to antibiotics by the example of ampicillin by using a biological sensor based on a slot mode in an acoustic delay line.
28 sie 2023 · Objectives: Identify the indications for the use of ampicillin. Describe the mechanism of action of ampicillin. Review the adverse effects associated with the use of ampicillin. Outline the role of interprofessional coordination in restricting unwarranted use of ampicillin and other antimicrobials.
21 cze 2017 · Antimicrobial susceptibility test methods include disk diffusion and minimal inhibitory concentration (MIC) methods, such as broth microdilution, agar dilution, and agar gradient diffusion. MIC tests often utilize semi- or fully automated platforms to decrease time to results and improve workflow.
29 paź 2015 · When tested with 20 μL samples of a model bacterial strain (E. coli ATCC 25922) treated with ampicillin or streptomycin, our method allows for the determination of minimum inhibitory concentrations consistent with the microdilution test in three hours, which is almost a factor of ten more rapid than the standard method.
