A U.S. team tests freezing blood from endangered animals to create a backup supply for life-saving transfusions.
Dr. Lily Parkinson is leading a U.S.-wide effort to create a frozen blood bank for endangered and exotic animals, testing whether red blood cells from giraffes, elephants, polar bears, and emus survive freezing and thawing for future transfusions.
Zoos are training animals to cooperate during blood draws without sedation, using treats as rewards.
Early results show giraffe and elephant blood cells hold up well, offering potential for treating elephants vulnerable to a deadly virus, while polar bear and emu samples show less resilience, suggesting needed adjustments.
The project aims to establish a centralized blood supply, enabling zoos to focus on treating sick animals without sourcing rare blood types.
The research is still in early stages.
