yes, clostridia does form spores.
You are probably correct about the production of the toxins under aerobic conditions.
Vaccination would provide protection against this germ.
I dunno - the last time I had a tetanus booster, my arm was swollen for about 2-3 days, and tender for about a week after that!!
It would take the threat of something before I volunteered for another one (damned college entrance requirements)
I feel pretty good though - seems my shot record is better than most - Hepatitis B, DPT regimen within last 5 years.
The only thing - I'm too young to have had smallpox vaccine
