The Efficacy of Disinfectants against Staphylococcus aureus ITU Isolates including Methicillin-Resistant S. aureus.

This study assessed the efficacy of disinfectants against methicillin-sensitive S. aureus (MSSA) and MRSA hospital isolates as determined by minimum inhibitory concentration (MIC) and surface efficacy tests. MIC determinations showed no difference between the susceptibility of the MSSA and MRSA isolates to sodium dichloroisocyanurate (NaDCC). Interestingly, all strains exhibited a high MIC for NaDCC compared with the in use concentration. Carrier tests showed both MSSA and MRSA strains can survive 30 sec exposures to the in-use NaDCC concentration when organic matter is present, whereas 1 min exposures were bactericidal i.e a high MIC for NaDCC against MSSA and MRSA strains did not predict a failure to kill the target organisms under dirty conditions.
