With an increase in the numbers of bacterial isolates resistant to first-line antibiotics, there has been a revival in the use of older drugs including fosfomycin. Although several commercial tests based on different techniques have been developed, Agar Dilution (AD) is considered the best method for performing Fosfomycin susceptibility testing so far.

The AD Fosfomycin 0.25-256 is the first and only (international patent pending) ready-to-use commercially available kit for performing the agar dilution antimicrobial susceptibility testing, in compliance with the CLSI and EUCAST standards, with 4 months shelf life at present.

The AD Fosfomycin panel comprises 12 wells, containing the antibiotic incorporated into an agar medium in different concentrations, i.e. 11 two-fold dilutions (0.25-256 μg/mL).

The ready-to-use Agar Dilution panels are available for custom versions with up to 4 weeks lead time.
