Experimental drug helping girl with brain eating parasite

An experimental drug couldbe the key to saving the 12-year-old girl who has a brain eating parasite.

"Day by day she'sshowing slow improvement and we're all very optimistic," said Dr. Sanjiy Pasala,a pediatrician at Arkansas Children's Hospital.

To preserve brain tissue KaliHardig's doctors induced a coma and cooled her body to 93 degrees. Doctors alsoturned to the Centers for Disease Control for an experimental anti-amoeba drug.

Now there's no trace ofthe amoebas in Kali's spinal fluid, but she still has a ways to go.

"Killing the amoebas isone thing, but managing brain swelling and the aftermath of the infection andthe irritation to the brain is really the critical part in having a patientsurvive," said Dr. Sanjiy.

If Kali can pull through,she'll beat the odds. Only two people have survived this disease.
