Without further qualification, if someone refers to themselves as vegetarian (in America), the general assumption is that they are lacto-ovo vegetarian. That means they don't eat animal products that require killing the animal, but eggs and dairy are fine.elatin is not vegetarian as it is made from dead animals... any vegetarian, from ovo-lacto in the liberal end to the fruitarian on the extreme end should have an aversion.
Spirilla is a serious bacteria that can cause illness in humans. Spirilla bacteria can be picked up via Lyme disease.
One enzyme contributes to the plant degradation process. Bacillus subtilis can also be found in the human body, mostly on the skin or in the intestinal tract. However it is very rare for this bacterium to colonize on the human body. Along with enzymes, Bacillus subtilis also produces a toxin called subtilisin. Subtilisin can cause allergic reactions if there is repeated exposure in high concentrations. This only poses a risk to fermentation plants that use high quantities of subtilisin.
