This prospective multicenter surveillance study was designed to provide antimicrobial susceptibility profiles of clinical anaerobic bacteria with genetic species identification in Japan. In 2014, a total of 526 non-duplicate clinical anaerobic isolates were collected from 11 acute-care hospitals in the Kyoto and Shiga regions of Japan. Genetic identification was performed using 16S rRNA sequencing. Read More

Animal botulism is primarily due to botulinum neurotoxin (BoNT) types C, D or their chimeric variants C/D or D/C, produced by Clostridium botulinum group III, which appears to include the genetically indistinguishable Clostridium haemolyticum and Clostridium novyi. In the present study, we used matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI TOF MS) to identify and characterize 81 BoNT-producing Clostridia isolated in 47 episodes of animal botulism. The instrument's default database, containing no entries for Clostridium botulinum, permitted reliable identification of 26 strains at the genus level. Read More
