High levels of the heme precursor, protoporphyrin, were found in a sample of 36 Aotus trivirgatus. The owl monkeys were of five different karyotypes and from three separate colonies. In many animals, a significant proportion of the protoporphyrin was not bound to zinc, as is normal, but existed as the free base protoporphyrin IX. The protoporphyrinemia may be related to major pathologies of captive Aotus.
