Tetanus in cattle in southern Brazil: study of 24 outbreaks. Pedro S. Quevedo I ; Silvia R. Ladeira II ; Mauro P. Twenty-four outbreaks of tetanus occurred in in beef cattle on farms located in the region of influence of the Regional Diagnostic Laboratory LRD , southern Rio Grande de Sul, are described.

Those were prolapse of the third eyelid, stiff gait, recumbency with limbs extended and off the ground spastic paralysis , very open eyelids, salivation, hyperexcitability, erect ears, mandibular trismus, food accumulation in the oral cavity, and presence of foam in mouth and nostrils in some cases. At postmortem some animals had necrosis, edema and hemorrhage surrounded by purulent exudate in the muscles where some medicine had been applied.

Blood serum and muscle fragments of affected animals were collected for subsequent inoculation into mice. No changes were evident in histological examination. The clinical and epidemiological data associated with the absence of histological lesions allowed the diagnosis of tetanus. The infection probably occurred during the vaccination procedure, by intramuscular injections using contaminated needles.

Although tetanus is not an important disease in the region, outbreaks could occur depending on epidemiological conditions. Appropriate care should be taken to avoid major economic losses as those that occurred in in the region. Index terms: Tetanus, Clostridium tetani, cattle.
