Tularemia in a group of nonhuman primates.

In an episode of tularemia in a Canadian zoologic garden, three black and red tamarins (Sanguinus nigricollis) and one talapoin (Cercopithecus talapoin) died. A second talapoin developed abscesses in the tongue and submandibular area; this animal recovered with treatment. Francisella tularensis was isolated from lung, liver, and spleen from each dead monkey and from pus collected from the tongue abscess of the sick talapoin. The attending veterinarian contracted the disease from a tamarin bite. The source of the disease was identified as wild ground squirrels, and the causative organism was recovered from the liver and spleen of one squirrel and from fleas found on it.
