B. procyonis as has some very unique adaptation which has made it so prevalent throughout many raccoon populations.  B. procyonis adults can make millions of eggs.  These said eggs are then deposited via the fecal matter of the raccoons.  3-4 weeks later the eggs can become infected.  After the eggs have become infected it is not uncommon too see the infected eggs survive in the environment for months to even years depending upon the location that the fecal matter was deposited.  This is just one adaptation that has made B. procyonis so prevalent throughout the raccoon species.  Besides B. procyonis having eggs that can survive for such extended amounts of time if the eggs are ingested it has been documented that B. procyonis can infect upwards to ninety animal species.  These are just a few of the things that make B. procyonis so prevalent.
