Not all parasites manifest with physical/outward symptoms....however more likely than not the necropsy and organs would show signs of parasites directly.
I can't think of any parasites that cause death without causing symptoms first, which ones were you thinking of?

And I've also never heard of IBD causing death without causing symptoms first. Boas can be asymptomatic, true, but they always present with symptoms before death.
