[Development and Evaluation of Screening Culture Medium for Detection of Drug-Resistant Gram Negative Rods Containing Stealth Type CPE].

There is a report that an infection by medicine resistant bacteria will be the number one cause of death in 2050 according to the recommendation of WHO, and the CPE (carbapenem-producing ) infection is regarded as a problem in particular. When detecting CPE, it is important how to detect stealth type CPE sensitive to carbapenem series medicines. 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.

[Clinical significance on MicroScan Rapid plus series using various antibiotic-resistant bacteria].

MicroScan Rapid plus Neg II Series and MicroScan Rapid plus Pos Series by Siemens Healthcare Diagnostics K.K. are the panels which enable to measure identification and antimicrobial susceptibility testing quickly and we have confirmed that it is useful for detecting drug resistance bacteria.

[Rapid detection of Vibrio vulnificus using a loop-mediated isothermal amplification method].

Vibrio vulnificus is found in marine waters near the coast around the world. Infection with this gram-negative rod, via ingestion of raw seafood or via a skin wound following contact with contaminated estuarine or marine water, can cause necrotizing fasciitis and sepsis. Most of patients with Vibrio vulnificus infection have underlying liver dysfunction or diabetes mellitus.

[Evaluation of rapid antimicrobial susceptibility test for Staphylococcus aureus by chemiluminescent assay and its application for screening of beta-lactam antibiotic induced vancomycin-resistant MRSA].

Minimum inhibitory concentrations (MICs) of vancomycin (VCM) and teicoplanin (TEIC) were measured using a novel susceptibility test based on the chemiluminescence assay method (CA) (Rapid-Lumi Eiken; Eiken Chemicals, Tokyo, Japan) against 84 strains of Staphylococcus aureus, consisting of 82 strains of methicillin-resistant S. aureus (MRSA) from clinical isolated, S. aureus Mu3 involving beta-lactam antibiotic induced vancomycin (VCM) resistant MRSA (BIVR) and methicillin-susceptible S.

A chromogenic substrate culture plate for early identification of Vibrio vulnificus and isolation of other marine Vibrios.

Vibrio vulnificus infection can result in necrotizing fasciitis and sepsis, which have short latentcy periods and high mortality rates. Thus, an easy and quick detection method is needed to improve the outcome. To distinguish V.
