Results: The best performance was observed for MHA from Becton Dickinson (BBL MHA II), bioMérieux (MHE agar) and Hardy Diagnostics, for which >97% of zone diameters were within QC ranges and >60% on target ±1 mm. The poorest performance was seen for plates from HiMedia (MHA and MHA No. 2), where 20 and 18% of readings were outside the QC ranges, respectively.
