Chimp Suffers from PTSD from Medical Testing

As part of a four-part series on chimpanzees in laboratories published this week, Wired.com tells the story of a chimpanzee named Katrina who was taken from her mother as an infant to be infected with HIV and hepatitis B and C, even though chimpanzees' bodies don't react to these diseases in the same way as humans' do. Katrina was anesthetized almost 300 times by the age of 15 and was never given any painkillers after numerous invasive liver biopsies. This caged, lonely life, punctuated by fear and pain, so traumatized Katrina that she developed symptoms of severe post-traumatic stress disorder and has lost a third of her body weight.
