The primary species affected were cyclopis monkeys (Macaca cyclopis) at the New England center and rhesus monkeys (Macaca mulatta) at the California center. Most of the monkeys were being raised for future research purposes. The investigators discounted any effects of treatments on those currently being used in research protocols.
"In recent years it became apparent that there were
