Emergence of a multidrug-resistant plasmid encoding , and in a clinical isolate of in Japan.

(formerly genospecies 15 Tjernberg and Ursing) has been isolated from humans and animals and was proposed to be a novel species in 2015. A multidrug-resistant isolate, RYU24, was obtained in 2012 from an inpatient in Okinawa, Japan, with no record of overseas travel. The isolate was resistant to carbapenems, aminoglycosides and ciprofloxacin, with minimum inhibitory concentrations (MICs) of 32 µg ml for imipenem and meropenem; > 1024 µg ml for amikacin, arbekacin, gentamicin and tobramycin; and 8 µg ml for ciprofloxacin.

An improved carbapenem inactivation method, CIMTrisII, for carbapenemase production by Gram-negative pathogens.

The modified carbapenem inactivation method (mCIM) is a simple phenotypic screening method for detecting carbapenemase production by Enterobacteriaceae and Pseudomonas aeruginosa. We recently developed another modified carbapenem inactivation method (CIMTris), in which carbapenemase is extracted from bacteria with Tris-HCl buffer, to detect carbapenemase production by Acinetobacter and Pseudomonas species. This study describes an improved carbapenem inactivation method, CIMTrisII, for detecting carbapenemase production by Gram-negative pathogens, including Enterobacteriaceae, Acinetobacter and Pseudomonas species.

A Modified Carbapenem Inactivation Method, CIMTris, for Carbapenemase Production in Acinetobacter and Pseudomonas Species.

The carbapenem inactivation method (CIM) and modified CIM (mCIM) are simple and economical phenotypic screening methods for detecting carbapenemase production in Gram-negative bacteria. Although the mCIM has been recommended by the Clinical and Laboratory Standards Institute, both the CIM and mCIM have limitations. This study describes another modified CIM, called CIMTris, in which carbapenemase was extracted from bacteria with 0.

Meningococcal pneumonia in Japan: A case report and literature review.

Neisseria meningitidis often causes meningitis and meningococcemia; however, meningococcal pneumonia is quite rare. Herein, we report a case of non-invasive meningococcal pneumonia initially misdiagnosed as pneumonia due to Moraxella catarrhalis on the basis of a Gram stain in a 43-year-old woman with asthma, type 2 diabetes mellitus, and schizophrenia. She visited our hospital following a 3-day history of fever, productive cough, and shortness of breath.
