For this question, it's helpful to understand how different types of toxins and different bacterial species work.
00:07
So here we have the tetanus toxin caused by clostridium tetanine.
00:15
We have the botulism toxin caused by clostridium botulinum.
00:23
We have endotoxin and we have the opportunistic toxin.
00:33
So tetanus and botulism work in very similar ways.
00:36
You have a bacterial cell, and they're going to make different a and b components to create a toxin.
00:45
And these are both going to be released into the host cell to cause, say, their toxic effect.
00:52
For this reason, certain substances or foods can be contaminated with either tetanus or botulism because our system is reacting to a toxin, which does not have to have a living environment, as opposed to, say, reacting to the bacterium itself.
01:10
We are able to ingest this toxin in the case of contaminated food in botulism, or it can be punctured into our skin, such as in the case of tetanus...
