Infestation (Ex)
Any living creature that takes damage from a rot grub swarm becomes infested unless it succeeds at a DC 19 Reflex save. On a failed save, the infested creature takes 1d4 points of Constitution damage per round as the rot grubs burrow through and consume its flesh-this effect continues as long as the victim remains in the swarm and continues for 1d6 rounds after it leaves the swarm. Any energy-based attack (including damage from negative energy) that deals at least 5 points of damage to the victim automatically destroys all of the rot grubs infesting it, ending the effect prematurely. Additionally, any effect that removes disease instantly ends a rot grub infestation. Immunity to disease offers no defense. The save DC is Constitution-based.Ecology

Rot grubs are foul, nauseating parasites that feed on flesh and use corpses as nests in which to grow. While a rot grub can derive nourishment from dead flesh, its true hunger is for the flesh of the living. Thankfully, rot grub swarms occur only rarely, as they require the infested carcass of a Huge or larger creature and many weeks to build up the numbers necessary to constitute a swarm.
In some cases, a rot grub continues to feed and grow, eventually reaching enormous size as a giant rot grub.
