A system rapidly detects and identifies pathogenic bacteria responsible for infection (particularly septicemia), and selects an appropriate antimicrobial drug. A method according to the present invention for detecting and identifying pathogenic bacteria includes performing gene amplification such as real-time PCR, and analyzing the combination of the melting temperatures (Tm values) determined by gene amplification product melting curve analysis or the difference between the Tm values. Specifically, real-time PCR is performed using 4 to 16 primer sets including 1 to 7 primer sets for the 16S ribosomal RNA of bacteria, 1 to 6 primer sets for the 18S ribosomal RNA of fungi, and one primer set respectively for the spa gene and the mecA gene specific to MRSA, and the combination of the Tm values of the amplification product or the combination of the differences between the Tm values is compared with a database to identify pathogenic bacteria responsible for septicemia. Pathogenic bacteria responsible for infection (particularly septicemia) can be rapidly detected and identified using the method according to the invention so that a rapid septicemia diagnosis method and evidence-based medicine in septicemia treatment are implemented.
