A Case Study of Rat Bite Fever Caused by Streptobacillus moniliformis.

We report a case of rat bite fever, diagnosed based on positive cultures of Streptobacillus moniliformis from blood and synovial fluid. The patient was a 45-year-old man who presented with history of a rat bite and alcoholic liver cirrhosis. He had been bitten on his third finger by a rat, which was caught in a mousetrap installed in his house.

[Analysis of extended-spectrum CTX-M-14 beta-lactamase (ESBLs) producing Escherichia coli isolates in the same ward over the long term].

We bacteriologically and genetically analysed 30 cephalosporin-resistant Escherichia coli strains isolated from specimens from 19 neurology-ward inpatients at our hospital over the 3 years from April 2006 to March 2009, surveying and comparing subjects' backgrounds. Of the 30, 19 (63%) were urine, 6 (20%) sputum, and 3 (10%) blood. We tested extended-spectrum beta-lactamase (ESBLs) production, found in all samples.
