Outline of Final Research Achievements |
Severe sepsis is a common and frequently fetal condition, but current biomarkers do not always reflect the severity of sepsis at a particular point in time. Here we show the development of a novel rapid identification and quantification method of unknown bacteria in a clinical sample using the original technology. We identified and quantified bacteria in septic blood samples, and the quantification results were correlated with the severity of microbial infection . We subsequently examined the time-dependent changes of blood bacterial concentration, and found that the time-dependent changes of blood bacterial concentration were not correlated with those of BT, WBC, CRP, IL-6, and Presepsin. In particular, 24 to 72 hours after antibiotic treatments, blood bacterial concentrations were dramatically decreased. In conclusion, blood bacterial concentration would be useful as a novel biomarker not only to estimate the severity of microbial infection but to monitor the therapeutic effect.
