Camelidae and Cervidae Tetanus Study Guide

Overview and Clinical Importance

Tetanus is a potentially fatal neurological disease caused by the neurotoxin tetanospasmin produced by Clostridium tetani, an anaerobic, spore-forming, gram-positive bacillus. While tetanus is relatively uncommon in camelids and cervids compared to horses, these species remain susceptible and cases are reported in veterinary literature. Understanding the pathophysiology, clinical presentation, and management of tetanus is essential for NAVLE success and clinical practice.

Camelids (llamas, alpacas, guanacos, vicunas) and cervids (deer, elk, reindeer, moose) represent expanding sectors of veterinary practice in North America and Europe. Tetanus in these species often follows wounds from castration, shearing, antler trauma, or environmental injuries. Early recognition and aggressive treatment are critical for survival.

Etiology

Causative Agent

Clostridium tetani is an obligate anaerobic, gram-positive, spore-forming bacillus. The organism is ubiquitous in the environment, found in soil (especially cultivated soil), dust, and the gastrointestinal tract of many animals including horses, cattle, sheep, and humans.
