    Botulism commonly affects water birds and it has recently been observed to be emerging in poultry production. In the present work, outbreaks of botulism in wild native species, such as the black-fronted Piping-guan (Aburria jacutinga), wild duck (Cairina moschata) and its crosses with mallard (Anas platyrhynchos), and domestic chickens (Gallus gallus domesticus) are described. Following treatments with a commercial botulism antitoxin CD, 28 (96. Read More

    Identification and characterization of Clostridium botulinum group III field strains by matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS).

    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

Electronic address:
    Susceptibility breakpoints provide fundamental information for rational administration of antibiotics. The present investigation reports the first valnemulin susceptibility breakpoint (MIC<0.25 μg/mL) against Clostridium perfringens infections in rabbits based on the wild-type cutoff (COWT) and the pharmacokinetics/pharmacodynamic (PK/PD) cutoff (COPD).
