Some were open with a bloody or purulent discharge See figure 5while others were closed, with no sign of external injury. The affected animals were treated with long acting oxytetracycline and removed from the oat crop.


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.

Response to treatment is generally good, but recurrence is common, particularly actinobqcillosis chronic cases Radostits et al, Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue.

The commensal bacteria is also commonly found in the oral cavity, gastrointestinal tract, and reproductive tract, sometimes resulting in disease. Klebsiella pneumoniae RhinoscleromaKlebsiella pneumonia Klebsiella granulomatis Granuloma inguinale Klebsiella oxytoca Escherichia coli: Faecal testing for worm eggs revealed no significant worm burden. The injury results in different forms and locations of the disease depending on the location of the tissue.

Exotic diseases that cause excessive salivation such as foot and mouth and bluetongue were also excluded based on clinical examination. 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.


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, We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes of the head and neck.

The most prominent symptom is the swelling of the tongue that protudes from the mouth and is very hard at palpation “wooden tongue”. It does not spread readily unless predisposing environmental conditions cause a high incidence of oral lacerations Radostits et al, Rickettsia felis Flea-borne spotted fever. Mouth actinobacillosis of cattle must be differentiated from actinomycosis that affects bone tissues of the maxilla.

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. Routine management advice was also given including recommendations to wormtest and drench if required.

Most broad spectrum antibiotics are effective Parkinson et al,and sensitivity testing confirmed that tetracyclines were likely to be effective against the causative agent in this case. Vibrio cholerae Cholera Vibrio vulnificus Vibrio parahaemolyticus Vibrio alginolyticus Plesiomonas shigelloides.

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

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.

Retrieved 7 October Pseudomonas aeruginosa Pseudomonas infection Moraxella catarrhalis Acinetobacter baumannii.

Rickettsia akari Rickettsialpox Orientia tsutsugamushi Scrub typhus. The eruption of teeth also commonly causes an ccattle point for the bacteria Jubb et al, actinbacillosis 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.


The involvement of other tissues, generally the skin or lymph nodes, has been regarded as atypical or cutaneous. Infectious diseases Bacterial disease: Actinobacillus suis is an important disease of pigs of all ages and can lead to severe morbidity and sudden death.

Actinobacillosis, two cases

Actinobacillosis is a disease of soft tissue, spreading as a lymphangitis involving regional lymph nodes, differentiating it from catttle, which causes bone lesions. Salmonella enterica Typhoid feverParatyphoid feverSalmonellosis. Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. Two cows also had moderate swelling of the caudal tongue. Tick-borne Rickettsia rickettsii Rocky Mountain spotted fever Rickettsia conorii Boutonneuse fever Rickettsia japonica Japanese spotted fever Rickettsia sibirica North Asian tick typhus Rickettsia australis Queensland tick typhus Rickettsia honei Flinders Island spotted fever Rickettsia africae African tick bite fever Rickettsia parkeri American tick bite fever Rickettsia aeschlimannii Rickettsia aeschlimannii infection.

The retropharyngeal and submaxillary lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al, Abbatoir surveys suggest that subclinical infections are common, particularly affecting the draining lymph nodes of the head Radostits et al The infection is most commonly cattld by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters.
