If you took a stool sample five days after Bronx was given the deworming treatment and then the sample showed no signs of worms, it likely means that the deworming treatment was effective and killed all the worms. The deworming treatment starts working within hours of administration to kill the worms present.

I know it can be confusing, but this happens quite often. When we check stool samples for parasites, we are looking for the eggs that they shed. Parasites shed eggs intermittently, so it is quite possible that the roundworms found in Bronx's stool weren't shedding eggs when you collected his stool sample.
