One animal was observed to have a small 5cm diameter granulomatous mass under the tongue figure 8.


Two cows also had moderate swelling of the caudal tongue. Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration.

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. Treatment recommendations vary, with reports of spontaneous recovery in untreated animals Radostits et al, 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 and feed bins.

We are unsure why the cattle on the first property presented with the cutaneous form in this instance. Affected cattle had elevated temperatures, ranging from Abbatoir surveys suggest that subclinical infections are common, particularly affecting the draining lymph nodes of the head Radostits et al actinobacillossi The retropharyngeal and submaxillary lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al, Broad spectrum long acting antibiotics were a more feasible and practical option.

The most prominent symptom is the swelling of the tongue that protudes from the mouth and is very hard at palpation “wooden tongue”. Parkinson et al reports a higher incidence of disease in cattle feeding on crops with awns, such as oats, and Jubb et al reports that the common primary lesion is caused by grass seeds and awns stuck in the lingual groove.


Natural lymphatic (“atypical”) actinobacillosis in cattle caused by Actinobacillus lignieresii.

A diagnosis of wooden tongue was made based on clinical signs, and the affected cows were treated with a single long acting Oxytetracycline injection. Pseudomonas aeruginosa Pseudomonas infection Moraxella catarrhalis Acinetobacter baumannii. 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.

Biopsies collected from several animals were sent to EMAI for testing Figure 9 and returned a pure growth of Actinobacillus lignieresii. The commensal bacteria is also commonly found in the oral cavity, gastrointestinal tract, and reproductive tract, sometimes resulting in disease.

The worst affected animals were standing with necks outstretched, drooling, with stridor and heavy breathing.

Actinobacillosis, two cases

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.

The eruption of teeth also commonly causes an entry point for the bacteria Jubb et al, They had been vaccinated with 5 in 1 at weaning, and had not been recently wormed. Actinobacillosis is a disease of soft tissue, spreading as a lymphangitis involving regional lymph nodes, differentiating it from actinomycosis, which causes bone lesions.

Rickettsia typhi Murine typhus Rickettsia prowazekii Epidemic typhusBrill—Zinsser diseaseFlying squirrel typhus. Several animals had mild swelling of the tongue and reduced muscle ctatle Figure 7causing the tongue to protrude. From Wikipedia, the free encyclopedia. Journal of Veterinary Medicine, Series A. Klebsiella pneumoniae RhinoscleromaKlebsiella pneumonia Klebsiella granulomatis Granuloma inguinale Klebsiella oxytoca Escherichia coli: The cattle were aged years and had been grazing oat stubble for the past three weeks, during which time the problem had noticeably worsened.


The affected animals were treated with long acting oxytetracycline and removed from the oat crop. The disease affected 40 of lactating cows in a dairy herd, and 5 of two-y-old steers in a beef herd.

Some were open with a bloody or purulent discharge See figure 5while others were closed, acctinobacillosis no sign of external injury. Histopathology reported Lymphadenitis, granulomatous, multifocal, chronic, and severe with intralesional Splendore-hoeppli material. The cattle were being fed oaten hay from hay feeders in a paddock, with access to sparse pasture — this property was also affected by long term drought. Cartle of the worst affected animals showed large, firm granulomatous masses in predominantly submandibular locations.

It is more commonly associated with animals than with humans. Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue. Prior to the oats, they had been grazing 3 year old wheat stubble, and had been early weaned due to prolonged drought conditions on the property.

Brucellaceae Brucella abortus Brucellosis. Actinobacillosis is a common diagnosis in cattle, but generally affects individual animals — it unusual to see such high numbers affected within a herd.
