Oregon Zoo's Asian elephant Rama tested positive for tuberculosis during annual screening. Only one of the three trunk fluid tests was positive for tuberculosis, according to the zoo's lead veterinarian, Mitch Finnegan, but Rama has been taken off exhibit and placed in quarantine. Eight instances of transmission of tuberculosis occurred between elephants and humans in 2009, according to the CDC, but Oregon Zoo staff say the public isn't at risk. Staff members who have had contact with Rama will be tested.
