A fatal epizootic of undetermined etiology in new world monkeys.

A peracute epizootic disease, strikingly characterized by profuse terminal hemorrhaging from the lungs, caused the deaths of 104 squirrel monkeys and 3 capuchin monkeys over a 22-month period. The case fatality rate was 100%. The pulmonary hemorrhaging was often accompanied by pulmonary edema and congestion, interstitial pneumonia, and hydrothorax.

Use of primates for wear testing of dental restorative materials.

The mechanical loss of substance, both of teeth and man-made materials used to fill or replace teeth, principally occurs by attrition (the grinding of one tooth against another) or abrasion due to coarse particles present in the diet, dentifrices, or as products of the grinding itself. Nonhuman primates often have pronounced grinding or bruxing habits that serve to sharpen the teeth. Papio anubis baboons were used as a model to study the ability of teeth and restorative materials to withstand continual two- or three-body wear.
