So we used the 2 types of screening culture medium, \"KBM\" CRE-JU culture medium ‹KOJINBAIO› (CRE-JU culture medium) and the FRPM culture medium, and tried to detect drug-resistant gram-negative bacilli such as CPE, stealth type CPE, ESBL-producing bacteria, and excess AmpC-producing bacteria (AmpC-producing bacteria), etc. in combination of this culture mediums. As a result, CRE-JU culture medium showed a difference in the growth of CPE depending on the amount of inoculated bacteria while β-lactamase non-producing strain and other strains except for high concentration ESBL-producing bacteria and AmpC-producing bacteria were un-growing.

From these results, it was suggested that when a strain grown on CRE-JU and FRPM culture mediums, it could be distinguished as CPE, and when strains grown on FRPM culture medium which were un-grown on CRE-JU culture medium, it could be distinguished as drug-resistant bacteria such as stealth type CPE, ESBL-producing bacteria, and AmpC-producing bacteria.

The nucleic acid to be analyzed is located inside the cell wall, the cell membrane or nuclear envelope. Therefore, it is essential to disassemble them in nucleic acid extraction operation.

Nucleic acid extraction is an indispensable task, but depending on the selected method, it may have a significant effect on the genetic test results. However, the DNA extraction method that is actually selected tends to emphasize work efficiency, and the appropriate evaluation of the extraction operation is neglected. In this study, we focused on the purity of the extracted DNA, and examined six existing extraction methods and original extraction methods using Gram-negative bacilli as a simple model. As a result, there was a large difference in DNA purity depending on the extraction method. When used in a qualitative gene amplification test, there was a difference in the shading of the bands.
