A Novel Paludibacterium Species Isolated from Human Blood

Akihiro Nakamura, Jun Murakami, Hitoshi Itohara, Tamaki Orita et autres

A novel facultatively anaerobic, Gram-negative, curved rod-shaped bacterium was isolated from blood cultures obtained from a patient with pyogenic spondylitis in Japan. The organism was additionally detected by 16S rRNA gene sequence analysis in a formalin-fixed, paraffin-embedded lumbar spine biopsy specimen from …

Laboratory Surveillance for Prospective Plasmid-Mediated AmpC β-Lactamases in the Kinki Region of Japan

Katsutoshi Yamasaki, Masaru Komatsu, Noriyuki Abe, Saori Fukuda et autres

Extended-spectrum beta-lactamases, plasmid-mediated AmpC beta-lactamases (PABLs), and plasmid-mediated metallo-beta-lactamases confer resistance to many beta-lactams. In Japan, although several reports exist on the prevalence of extended-spectrum beta-lactamases and metallo-beta-lactamases, the prevalence and characteristics of PABLs remain unknown. To investigate the production of PABLs, …

Extended-Spectrum-^|^beta;-Lactamase-Producing Proteus mirabilis: Laboratory-Based Surveillance in Cooperation with 12 Clinical Laboratories in the Kinki Region of Japan

Tatsuya Nakamura, Masaru Komatsu, Kouichi Shimakawa, Noriyuki Sueyoshi et autres

We studied 247 strains of Proteus mirabilis collected during the 6 months from November 2003 to April 2004 from 12 clinical laboratories in the Kinki region of Japan for the production of extended-spectrum beta-lactamase (ESBL). Eighteen strains (7.3%) showed MICs for cefpodoxime …
