Since it is a bacteria, it can take the intestines a dose to get used to.

It is a bacteria?  I understood that it is a "fermentation product" of a bacteria.

"A palatable, beef-flavoured tablet, Comfortis starts to kill fleas within 30 minutes, providing 100 per cent control in four hours, the fastest specific claim of any approved flea preventive. It is based on a unique active ingredient, Spinosad, a naturally occurring fermentation product of soil bacteria  with a unique insecticidal effect. "

From Cornell:

"Spinosad is composed of spinosyns A and D, substances produced by aerobic fermentation of the actinomycete species Saccharopolysora spinosa. This rare species was found in soil samples from an island in the Caribbean in 1982. Actinomycetes are filamentous bacteria found in the soil that give it a sweet ‘healthy’ smell."
