SpectraTM MRSA was able to rapidly identify and differentiate methicillin–resistant S. aureus from methicillin–susceptible S. aureus based on the utilization of chromogens that result in denim blue colonies, thus eliminating the need for biochemical analysis and antimicrobial susceptibility testing. Extending the incubation beyond 24 h did not significantly improve the recovery of MRSA and resulted in decreased specificity read more

The aminoglycosides and fluoroquinolones exhibit ‘concentration-dependent killing’ and so higher doses are associated with greater efficacy. β-Lactams, erythromycin, clindamycin, and linezolid demonstrate ‘time-dependent killing’ and therefore duration above minimum inhibitory concentration is more important. read more
