Multiple animals had large nodular masses evident, predominantly under the jaw, but some animals also had masses protruding from their flanks See figure 4and one had a large mass in the inguinal region. Actinobacillosis is not considered a high risk zoonotic disease, but the organism has been isolated from bite wounds inflected by cattle Radostits et al, actinoabcillosis, so care should be taken when investigating these cases.

The worst affected animals were standing with necks outstretched, drooling, with stridor and heavy breathing. Faecal testing for worm eggs revealed no significant worm burden. The situation resolved to a point that affected animals were no longer easily identifiable in the paddock.

Actinobacillosis, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals. Retrieved from ” https: It is difficult to prevent the disease except through minimizing exposure to rough or spiky feedstuffs Parkinson et al,which can prove difficult under drought conditions.

Retrieved 7 October Actinobacillosis is a common diagnosis in cattle, but generally affects individual animals — it unusual to see such high numbers affected within a herd.

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. We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes of the head and neck. Two cows also had moderate swelling of the caudal tongue.



Salmonella enterica Typhoid feverParatyphoid feverSalmonellosis. The affected animals were treated with long acting oxytetracycline and removed from the oat crop. The most prominent symptom is the swelling of the tongue that protudes from the mouth and is very hard at palpation “wooden tongue”. Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue.

The retropharyngeal and submaxillary lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al, It is more commonly associated with animals than with humans. Histopathology reported Lymphadenitis, granulomatous, multifocal, chronic, and severe with intralesional Splendore-hoeppli material.

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. Treatment recommendations vary, with reports of spontaneous recovery in untreated animals Radostits et al, Cutaneous Actinobacillosis is reportedly uncommon, presenting as lesions on the flanks and thighs in the form of large ulcers or nodules which may exude pus Radostits et al, This page was last edited on 1 Octoberat It does not spread readily unless predisposing environmental conditions cause a high incidence of oral lacerations Radostits et al, The recommended treatment of sodium iodide was prohibitively expensive in these cases.

Anaplasma phagocytophilum Human granulocytic anaplasmosisAnaplasmosis Ehrlichia chaffeensis Human monocytotropic ehrlichiosis Ehrlichia ewingii Ehrlichiosis ewingii infection.

Rickettsia felis Flea-borne spotted fever. 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. Several animals had mild swelling of the tongue and reduced muscle tone Figure 7causing the tongue to protrude.

A landholder reported cattle with excessive drooling, bottle jaw and open lesions around the jaw and neck on an extensive grazing property in Burren Junction, North Western NSW.

Actinobacillosis, two cases

actinlbacillosis Mouth actinobacillosis of cattle must be differentiated from actinomycosis that affects bone tissues of the maxilla. We are unsure why the cattle on the first property presented with the cutaneous form in this instance. Routine management advice was also given including recommendations to wormtest and drench if required.


A diagnosis of wooden tongue was made based on clinical signs, and the affected cows were treated with a single long acting Oxytetracycline injection. Journal of Veterinary Medicine, Series A. Klebsiella pneumoniae RhinoscleromaKlebsiella pneumonia Klebsiella granulomatis Granuloma inguinale Klebsiella oxytoca Escherichia coli: Actinobacillus lignieresii was isolated from cattlw lesions and identified by amplification, sequencing, and analysis of the 16S ribosomal r DNA gene.

From Wikipedia, the free encyclopedia. Response to treatment is generally good, but recurrence is common, particularly in chronic cases Radostits et al, Pseudomonas aeruginosa Pseudomonas infection Moraxella catarrhalis Acinetobacter baumannii.

The histologic lesions were multifocal pyogranulomatous lymphadenitis, dermatitis, and cellulitis with Splendore-Hoeppli material. Journal of Veterinary Diagnostic Investigation.

Vibrio cholerae Cholera Vibrio vulnificus Vibrio parahaemolyticus Actinlbacillosis alginolyticus Plesiomonas shigelloides. The involvement of other tissues, generally the skin or lymph nodes, has been regarded as atypical or cutaneous. On examination, the affected cows were found to have cm diameter granulomatous lesions in the submandibular region. The masses ranged from cm diameter, and were not attached to bone.

Actinobacillosis – Wikipedia

Broad spectrum long acting antibiotics were a more feasible and practical option. Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. They had been vaccinated with 5 in 1 at weaning, and had not been recently wormed. 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.
