Antimicrobial Susceptibility Testing
New Fosfomycin Agar Dilution panel

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 new 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 3 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 AD Fosfomycin 0.25-256 panel is the first of a series of agar dilution panels, which will be available as both standard and custom versions, in terms of antibiotics and concentrations.

New EUCAST ESBL confirmation disc kit

ESBL detection involves two important steps. The first is a screening test with an indicator cephalosporin which looks for resistance or diminished susceptibility, thus identifying isolates likely to be harboring ESBLs. The second step is a confirmation test which evaluates the synergy between an oxyimino cephalosporin and clavulanic acid, distinguishing isolates with ESBLs from those that are resistant for other reasons.

The new ESBL confirmation disk kit recommended by EUCAST includes Cefotaxime 5 µg, Cefotaxime + Clavulanic acid 5+10 µg, Ceftazidime 10 µg, Ceftazidime + Clavulanic acid 10+10 µg, Cefepime 30 µg, Cefepime + Clavulanic acid 30+10 µg.
