A Complete Guide to Tetanus in Alpacas
Tetanus, or lockjaw, is a deadly disease of alpacas caused by the bacterium Clostridium tetani. The spores live in soil and manure and enter through wounds, even small cuts from shearing, castration or bites. Signs usually appear 3 to 21 days later and include a stiff gait, reluctance to move, reduced jaw movement, difficulty eating, rigid posture, painful muscle spasms and trouble breathing. Diagnosis is based on recent wounds, vaccination history and classic signs. Treatment may use tetanus antitoxin, antibiotics, wound cleaning, pain relief and intensive nursing, but recovery is rare once nerve signs develop. Prevention is vital: vaccinate (two primary doses then yearly boosters, with a pre-birth booster for pregnant females), give antitoxin after severe wounds in unvaccinated animals, clean and treat wounds promptly, use sterile needles and keep housing dry and free of sharp objects. Tetanus in alpacas has a high welfare and financial cost, so contact your veterinary surgeon straight away for unexplained stiffness, wounds that look infected, difficulty swallowing or muscle spasms.
