Prior to the oats, they had been grazing 3 year old wheat stubble, and actinibacillosis been early weaned due to prolonged drought conditions on the property.


The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters. The histologic lesions were multifocal pyogranulomatous lymphadenitis, dermatitis, and cellulitis with Splendore-Hoeppli material.

Two cows also had moderate swelling of actinobacllosis caudal tongue. Treatment recommendations vary, with reports of spontaneous recovery in untreated animals Radostits et al, By using this site, you agree to the Terms of Use and Privacy Policy.

One steer had an exophytic pyogranuloma in the gingiva and another died because of ruminal tympany secondary to oropharyngeal and esophageal obstruction by a pyogranulomatous mass. On examination, the actinobaccillosis cows actinobacilloss found to have cm diameter granulomatous lesions in the submandibular region.

Abbatoir surveys suggest that subclinical infections are common, particularly affecting the draining lymph nodes of the head Radostits et al Actinobacillus on is an important disease of pigs of all ages and can lead to severe morbidity and sudden death.

Examination of the worst affected animals showed large, firm granulomatous masses in predominantly submandibular locations. Interestingly, both herds were eating oats — stubble and hay — and we had further anecdotal reports from other landholders around the same time of cattle on oat stubble being affected with suspected wooden tongue.

Broad spectrum long acting antibiotics were a more feasible and practical option. Seven of 8 cows recovered after treatment with sodium iodide.

The bacteria is reported to survive for up to 5 days in the environment Radostitis et catlte,therefore in both cases it was recommended that affected cattle be removed from the rest of the herd to avoid further contamination of the paddock and feed bins.
