| Outline of Final Research Achievements |
Because Clostridium botulinum types C and D produce botulinum neurotoxin, causing serious symptom botulism, they are recognized as severe pathogen you should prevent spreading in food and animal industries. The botulinum neurotoxin genes are coded on the prophage genomes, and so inhibition of lateral gene transfer mediated by bacteriophage (phage) can be one of the preventions for the disease. Thus, we investigated the adsorption mechanism of C. botulinum type C neurotoxin-converting phage, phage c-st on the genetic point. Based on the comparative genomics and identification of phage virion genes, we got at a speculation that several genes associated with phage adsorption. We are in advanced studies of the findings.
