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.
AD Fosfomycin 0.25-256 is a 12-well panel containing the antibiotic incorporated into an agar medium in
different concentrations, i.e. 11 two-fold dilutions (0.25 - 256 µg/mL). The device is used to perform the AD
method for the antimicrobial susceptibility testing of fosfomycin as recommended by CLSI and EUCAST standards
but in a simpler and less time-consuming way.
