Evaluation of a new inoculum standardization device and a fast susceptibility testing medium for Staphylococcus aureus antimicrobial susceptibility testing
01/2012
New device INOCLIC™ for inoculum preparation and standardization, and new rapid medium MHR-SIR™ were tested for Staphylococcus aureus A.S.T. Sixty five different clinical strains of S. aureus, including fifteen Methicillin-Resistant S. aureus (MRSA) strains, were tested using two different methods for inoculum standardization: Inoclic device (i2a, Montpellier, France) versus standard 0.5 McFarland suspension according to CLSI guidelines. And two different culture media: classical Mueller-Hinton medium (MH, i2a, Montpellier, France) versus fast Mueller-Hinton medium (MHR-SIR™, i2a, Montpellier, France).
