Original Toronto Star caption: Tuberculosis tests have resulted in a positive reaction by more than 100 large animals at the new Metro Zoo; including a herd of wisents; a European deer. The zoo might have to slaughter the affected animals-camels; yaks and several varieties of antelope; as well as the deer-which are valued at about $200;000. All of them have been imported in the past few months and none is on display.
