The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters. The cattle actinobacilllosis being fed oaten hay from hay feeders in a paddock, with access to sparse pasture — this property was also cattlf by long term drought.
Several animals had mild swelling of the tongue and reduced muscle tone Figure 7causing the tongue to protrude.
Vibrio cholerae Cholera Vibrio vulnificus Vibrio parahaemolyticus Vibrio alginolyticus Plesiomonas shigelloides.
Actinobacillosis, two cases
These soft tissues include subcutaneous tissues, the tongue, lymph nodes, lungs, and various tissues in the gastrointestinal tract. The worst affected animals were standing with necks outstretched, drooling, with stridor and heavy breathing. Lymphatic actinobacillosis is a frequent disease in Uruguay, southern Brazil, and Argentina. Brucellaceae Brucella abortus Brucellosis.
Exotic diseases that cause excessive salivation such as foot and mouth and bluetongue were also excluded based actinobacillsis clinical examination. The eruption of teeth also commonly causes an entry point for the bacteria Jubb et al, On examination, the affected cows were found to have cm diameter granulomatous lesions in the submandibular region.
The injury results in different forms and locations of the disease depending on the location of the tissue.
Examination of the worst affected animals showed large, firm granulomatous masses in predominantly submandibular locations. Other differentials we considered were foreign bodies, grass seed abscesses, intestinal worms, Actinomycosis, granulomas and neoplastic growths.
Actinobacillosis is a disease of soft tissue, spreading as a lymphangitis involving regional lymph nodes, differentiating it from actinomycosis, which causes bone lesions.
Histopathology cxttle Lymphadenitis, granulomatous, multifocal, chronic, and severe with intralesional Splendore-hoeppli material. We are unsure why the cattle on the first property presented with the cutaneous form in this instance.
It is more commonly associated with animals than with humans. One animal was observed to have a small 5cm diameter granulomatous mass under the tongue figure 8. The affected animals were treated with long acting oxytetracycline and removed from the oat crop.
Actinobacillosis – Wikipedia
Antibiotic sensitivity testing of the cultured bacteria revealed sensitivity to a range of common antibiotics including tetracyclines.
Retrieved from ” https: In the following cases, signalment, diet and environmental conditions combined to cause outbreaks of the condition within these herds.
Routine management advice was also given including recommendations to wormtest and drench if required. The masses ranged from cm diameter, and were not attached to bone.
Actinobacillus lignieresii is a normal inhabitant of the oral cavity and rumen Radostits et al,and infection occurs due to damage to the oral mucosa.
Multiple or single, occasionally ulcerated nodules were observed in the region of the mandible, neck, and shoulder, including the parotid, submandibular, retropharyngeal, and prescapular lymph nodes. Actinobacillosis is a cattlle disease caused by Actinobacillus. 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.

Rickettsia typhi Murine typhus Rickettsia prowazekii Epidemic typhusBrill—Zinsser diseaseFlying squirrel typhus. It does not spread readily unless predisposing environmental conditions cause a high incidence of oral lacerations Radostits et al, Treatment recommendations vary, with reports of spontaneous recovery in untreated animals Radostits et al, Mouth actinobacillosis of cattle must be differentiated from actinomycosis that affects bone tissues of the maxilla.
Actinobacillosis
Affected cattle with draining pyogranulomas contaminate the environment, favoring disease transmission, and should be treated with sodium iodide or antibiotics and isolated from the herd in order to control the disease. Klebsiella pneumoniae RhinoscleromaKlebsiella pneumonia Klebsiella granulomatis Granuloma inguinale Klebsiella oxytoca Escherichia coli: The bacteria is reported to survive for up to 5 days in the environment Radostitis et al,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 cathle feed bins.
This page was last edited on 1 Octoberactinobacillosks Actinobacillosis, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals. Both of these herds were subject to considerable stresses, catle nutritionally due to prolonged drought, and physiologically, with one mob teething, and the other with young calves at foot. The situation resolved to a point that affected animals were no longer easily identifiable in the paddock.
Actinobacillosis is not considered a high risk zoonotic disease, but the organism has been isolated from bite wounds inflected by cattle Radostits et al,so care should be taken when investigating actinobacillozis cases.
Rickettsia felis Flea-borne spotted fever. Journal of Veterinary Diagnostic Investigation. None were observed to have lesions within the oral cavity.
