- Introduction: Tetanus is a neuromuscular disorder of animals and humans and is also an infectious and potentially fatal disease, caused by Clostridium tetani. Tetanospasmin as a tetanus neurotoxin affects the nervous system. The spore is introduced to animal tissue through wounds, particularly deep ones, sometimes this infection happens due to dystocia. This study mentioned the sheep's tetanus because of the dystocia.
- Methods: During the lambing season, two flocks of Ile-du-France (2 sheep) and Romane (2 sheep) had dystocia, the signs of muscle spasms were seen, so we suspected tetanus. Bacteriological swabs were taken from the depth of the related wound. Swabs were cultured in an anaerobic condition for 48 hours at 37℃ and then the smear of that was taken.
- Results: According to the clinical signs, which were stiffness, the rigidity of the neck and limbs, bloat, hypersensitivity, pricked ears, prolapse of the third eyelid and morphology of the C.tetani, gram-positive rods with terminal spores(tennis racket), and hemolytic colony that were visible on the blood agar media, and also biochemical tests, clostridium tetani was diagnosed as the cause of tetanus.
- Conclusion: Control and prevention of tetanus are efficient and have beneficial costs, but because of the high incidence in flocks, it is recommended to include the tetanus vaccine with other clostridial vaccines in the sheep flocks.
