Bovine TB tests have been carried out on other animals at a Devon zoo where a herd of antelope have been put down because of the disease.
Paignton Zoo culled the lechwe antelope after one of its animals tested positive for TB. Staff were "saddened" by the cull, which saw 10 animals killed, it said.
Senior head keeper of mammals Rob Rouse said the cull was also partly carried out because there were "other species here that are vulnerable".
He said elephants, giraffes, kangaroos, goats and sheep could be affected.
He added: "Some have also already been TB tested and those have come back negative."
Sir David Attenborough spoke to the BBC about Zoo Quest, the environment and the planet's future.
