Abstract
In the present study, we use chrOMagar TM medium as a rapid method taking only 24 hrs. for MRSA detection from 70 clinical specimens (exudates or pus) and 25 nasal swabs (health care personnel) in comparison to the conventional method which needs 48 hrs., the validity values obtained were 100% sensitivity, specificity, PPV and NPV of cefoxitin disc diffusion method versus 93.8% sensitivity, 100% specificity, 100% PPV and 97% NPV of the chromogenic agar in identification of MRSA isolates from nasal swabs, burn and wound discharge samples collectively. Also we test the effect of some antiseptics Agents on the MRSA isolates. The used antiseptics were acetic acid (5%), betadine (10%), sodium hypochlorite´´ dakin’s solution´´ (4%) and H2O2 (10%). Minimal inhibitory concentration (MIC) & minimal bactericidal concentration (MBC) of the different antiseptics were measured against the MRSA isolates. These results revealed that acetic acid was effective in the range of 5% to 0.63%, while betadine was effective in the range of 10% to 1.25%, also H2O2 was effective in the range of 10% to 0.63% but Dakin’s solution was effective in the range of 0.5% to 0.063%.
