Clinical description of tetanus in squirrel monkeys (Saimiri sciureus).

Abstract

Nineteen cases of clinical tetanus developed in Bolivian squirrel monkeys (Saimiri sciureus) which were housed in outdoor corrals with soil-based floors. The disease was initially characterized by stiffness in gait followed by extensor rigidity, trismus and opisthotonus. Eleven of the 19 monkeys (58%) had evidence of external wounds. The case fatality rate was 100%. Tetanus accounted for 12% of adult female and 19% of adult male mortalities in the colony. Immunization with tetanus toxoid was effective in reducing the incidence of tetanus.
