title: Suppurative bite wound by repetitive aggression of dominance hierarchy during group housing in rhesus monkeys.
abstract: Group formation of rhesus monkeys, often leads to victims of repeated attacks by the high ranking animal. We reported a case of an injured middle ranking monkey from repetitive and persistent aggression. 4-male rhesus group was formed by a rapid group formation strategy 2 years ago. One monkey in the group suddenly showed depressive and reluctant movement. Physical examination revealed multiple bite wounds and scars in the dorsal skin. Overall increased opacity of the dorsal soft tissue and some free air was observed on radiographic examination. An unidentified anaerobic gram negative bacillus was isolated from the bacterial culture. Reconstructive surgery was performed and in consequence, the wound was clearly reconstructed one week later. Eventually, the afflicted monkey was separated and housed apart from the hierarchical group. This case report indicate that group formation in rhesus monkeys is essentially required sufficient time and stages, as well as more attention and a progressive contact program to reduce animal stress and fatal accidents.
