First Isolation of carbon dioxide-dependent Proteus mirabilis from an uncomplicated cystitis patient with Sjögren's syndrome.

An uncomplicated cystitis caused by CO2-dependent Proteus mirabilis was observed in a 64-year-old Japanese female patient with Sjögren's syndrome in the Aomori Kyoritsu Hospital, Aomori, Japan. The initial P. mirabilis isolate came from a midstream urine specimen containing large numbers of Gram-negative, rod-shaped organisms that failed to grow on both Drigalski agar and sheep blood agar incubated in ambient air.

Typing of Clostridium difficile isolates endemic in Japan by sequencing of slpA and its application to direct typing.

A typing system for Clostridium difficile using sequencing of the surface-layer protein A encoding gene (slpA) was evaluated and used to analyse clinical isolates in Japan. A total of 160 stool specimens from symptomatic patients in Japan was examined and 87 C. difficile isolates were recovered.
