Broad spectrum long acting antibiotics were a more feasible and practical option. Most broad spectrum antibiotics are effective Parkinson et al,and sensitivity testing confirmed that tetracyclines were likely to be effective against the cattel agent in this case. The eruption of teeth also commonly causes an entry point for the bacteria Jubb et al, Salmonella enterica Typhoid feverParatyphoid feverSalmonellosis.

Actinobacillosis, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals. On examination, the affected cows were found to have cm diameter granulomatous lesions in the submandibular region.

Six months later on a nearby property at Burren Junction, 15 Angus x Hereford cows in a mob of 40 with calves at foot were observed with similar lesions. It is difficult to prevent the disease except through minimizing exposure to catfle or spiky feedstuffs Parkinson et al,which can prove difficult under drought conditions.

These soft tissues include subcutaneous tissues, the tongue, lymph nodes, lungs, and various tissues in the gastrointestinal tract.

The injury results in different forms and locations of the disease depending on the location of the tissue. This page was last edited on 1 Octoberat 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.

Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue. Mouth actinobacillosis of cattle must be differentiated from actinomycosis that affects bone tissues of the maxilla.

Interestingly, both herds were eating oats — stubble and hay — and actinobqcillosis had further anecdotal reports from other actinobbacillosis around the same time of cattle on oat stubble being affected with suspected wooden tongue. They had been vaccinated with 5 in 1 at weaning, and had not been recently wormed. 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, Other differentials we considered were foreign bodies, grass seed abscesses, intestinal worms, Actinomycosis, granulomas and neoplastic growths.

Faecal testing for worm eggs revealed no significant worm burden. Views Read Edit View history. The recommended treatment of sodium iodide was prohibitively expensive in these cases. Journal of Veterinary Diagnostic Investigation. Rickettsia akari Rickettsialpox Orientia tsutsugamushi Scrub typhus. From Wikipedia, the free encyclopedia. It is more commonly associated with animals than with humans. Enterotoxigenic Enteroinvasive Enterohemorrhagic O Two cows also had moderate swelling of the caudal tongue.

Treatment recommendations vary, with reports of spontaneous recovery in untreated animals Radostits et al, The histologic lesions were multifocal pyogranulomatous lymphadenitis, dermatitis, and cellulitis with Splendore-Hoeppli material. Some were open with a bloody or purulent discharge See figure 5while others were closed, with no sign of external injury.

Routine management advice was also given including recommendations to wormtest and drench if required. Exotic diseases that cause excessive salivation such as foot and mouth and bluetongue were also excluded based on clinical examination. Vibrio cholerae Cholera Vibrio vulnificus Vibrio parahaemolyticus Vibrio alginolyticus Plesiomonas shigelloides.

A diagnosis of wooden tongue was made based on clinical signs, and the affected cows were treated with a single long acting Oxytetracycline injection.

One animal was observed to have a small 5cm diameter acginobacillosis mass under the tongue figure 8. We are unsure why the cattle on the first property presented with the cutaneous form in this instance.

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.

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. Actinobacillosis is a disease of soft tissue, spreading as a lymphangitis involving regional lymph nodes, differentiating it from actinomycosis, which causes axtinobacillosis lesions. Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. The cattle were aged years and had been grazing oat stubble for the past three weeks, during which time the problem had noticeably worsened.

CASE NOTES

The disease affected 40 of lactating cows in a dairy herd, and 5 of two-y-old steers in a beef herd. All articles with dead external links Articles with dead external links from October Articles with permanently dead external links Infobox medical condition. None were observed to have lesions within the oral cavity.

The worst affected animals were standing with necks outstretched, drooling, with stridor and heavy breathing. Pseudomonas aeruginosa Pseudomonas infection Moraxella catarrhalis Acinetobacter baumannii. We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes of the head and neck.

The retropharyngeal and submaxillary lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al,
