Naegleria fowleri, the rare, but deadly, so-called brain-eating amoeba, can be found in Pennsylvania's waters.

The parents of Jaysen Carr, a 12-year-old who died July 18 from a brain-eating amoeba after swimming in a South Carolina lake, say warnings should be put in place to prevent similar tragedies.

The infection destroys brain tissue, which is why the infection is commonly referred to as a brain-eating amoeba.
