Agar Dilution HEAR (High-Efficiency Agarose Resistance) is a sophisticated methodology employed in the microbiological analysis of antimicrobial resistance. This technique is integral to the development and testing of AffiBIOTICS products, which are designed to enhance the accuracy and efficiency of susceptibility testing in various bacterial strains.
Technical Process
The Agar Dilution HEAR method involves preparing a series of agar plates with varying concentrations of antimicrobial agents. These plates are inoculated with a standardized bacterial suspension, and the growth inhibition zones are subsequently measured to determine the minimum inhibitory concentration (MIC) of the tested agents.
- Preparation of Agar Plates:
- High-quality agarose is used to prepare the base agar plates. The agarose concentration is carefully adjusted to ensure optimal gel formation and uniform diffusion of antimicrobial agents.
- A series of agar plates are prepared with different concentrations of the antimicrobial agents, ranging from low to high concentrations.
- Inoculation:
- A standardized bacterial suspension, typically at a concentration of 1 × 10^5 CFU/mL, is prepared using a broth culture of the target bacteria.
- The suspension is evenly spread across the surface of the agar plates using a sterile spreader.
- Incubation:
- The inoculated agar plates are incubated at 37°C for 18-24 hours. During this period, bacterial growth and the effect of the antimicrobial agents are monitored.
- Evaluation:
- After incubation, the MIC is determined by measuring the lowest concentration of the antimicrobial agent at which bacterial growth is inhibited.
- The results are recorded and analyzed to assess the susceptibility of the bacteria to the antimicrobial agents.
