Objective. To compare the results of molecular biological and bacteriological studies to identify blood methicillin-resistant staphylococcus strains.
Subjects and methods. A parallel bacteriological and molecular biological (real-time PCR) study was conducted to examine biomaterials from 240 patients with signs of infection who were treated in a Moscow multidisciplinary hospital. The biological material was peripheral vein blood taken in vacuum test tubes with EDTA for PCR and in vials containing a nutrient medium for bacteriological testing.
Results. The sensitivity and specificity of the PCR assay versus the bacteriological test in detecting blood methicillin-resistant staphylococci were 100 and 97%, respectively. Methicillin-resistant staphylococci were detected by PCR in 6.3% of patients with signs of infection and by bacteriological tests in 3.3% of patients.
Conclusion. The real-time PCR assay used for the detection of blood methicillin-resistant staphylococci will be able to reduce the time of a diagnostic study, to increase the possibility of identifying the etiological agent for bacteremia, and to timely perform adequate antimicrobial therapy.
