[Updated at 3:57 p.m. ET] A University of West Georgia graduate psychology student is fighting for her life with flesh-eating bacteria after falling off a homemade zip line and cutting her leg, CNN affiliates WSB report and WXIA report.

Aimee Copeland, 24, fell off a homemade zip line near a friend’s home in Carroll County, Georgia, on May 1. Doctors at a hospital in Augusta were forced to amputate most of her right leg on Friday after the bacteria destroyed her leg muscles and moved into other parts of her body. She stopped breathing and at one point and had to be resuscitated, her father, Andy Copeland, told WSB.

On Thursday, Andy Copeland told the Atlanta Journal-Constitution that her hands and her remaining foot also will have to be amputated.

But he said she was showing improvement at a hospital in Augusta and was "extremely responsive, coherent and alert" on Thursday, the AJC reported.

The AJC reported that Copeland contracted Aeromonas hydrophila in the deep gash in her leg after the zip line broke.
