(CNN) -- Tests done on 12-year-old Zachary Reyna show no signs of activity from the brain-eating parasite he contracted earlier this month, according to his father.
Doctors had given Zachary the same experimental anti-amoeba drug used to treat 12-year-old Kali Hardig recently in Arkansas, the Reyna family told CNN affiliate WBBH.
The Arkansas girl is only the third person in the last 50 years to survive this deadly parasite.
Extensive damage has been done to Zachary's brain, his father wrote Wednesday on a Facebook page dedicated to the Little League baseball player. Right now the family is looking for signs that his brain is still active.
"This is a small victory but we know the battle is not over," he wrote. "I feel like Zac was in a slump. ... All ball players go through them. We all do. As his Dad and Coach I do all I can to help him get out of it by giving him extra training and making adjustments to his swing. We all go through tough times and we need to find God and prayer to get through theses slumps of life."
The Centers for Disease Control and Prevention says it will make the experimental drug that helped fight Zachary's amoeba available to physicians who consult it.
