Views Read Edit View history. 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. Pseudomonas aeruginosa Pseudomonas infection Moraxella catarrhalis Acinetobacter baumannii. The recommended treatment of sodium iodide was prohibitively expensive in these cases.
Acfinobacillosis actinobacillosis of cattle must be differentiated from actinomycosis that affects bone tissues of the maxilla.
Actinobacillosis
The disease affected 40 of lactating cows in a dairy herd, and 5 of two-y-old steers in a beef herd. Antibiotic sensitivity testing of the cultured bacteria revealed sensitivity to a range of common antibiotics including tetracyclines.
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.
Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. 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 these cases.
Actinobacillosis – Wikipedia
The affected animals were treated with actinobacullosis acting oxytetracycline and removed from the oat crop. Actinobacillosis, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals.
The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters.
Journal of Veterinary Medicine, Series A. 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.
Both of these herds were subject to considerable stresses, both nutritionally due to prolonged drought, and physiologically, with one mob teething, and the other with young calves at foot.
Some were open with a bloody or purulent discharge See figure 5while others actinobacillois closed, with no sign of external injury. Actinobacillosis is a common diagnosis in cattle, but generally affects individual animals — it unusual to see such high numbers affected within a herd. Seven of 8 cows recovered after treatment with sodium iodide.
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. It is more commonly associated with animals than with humans.
Abbatoir surveys suggest that subclinical infections are common, particularly affecting the draining lymph nodes of the head Radostits et al Klebsiella pneumoniae RhinoscleromaKlebsiella pneumonia Klebsiella granulomatis Acfinobacillosis inguinale Klebsiella oxytoca Escherichia coli: Biochemistry on two affected animals showed one had a mild copper deficiency 7.
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. In the following cases, signalment, diet and environmental conditions combined to cause outbreaks of the condition within these herds.
Interestingly, both herds were eating oats — stubble and hay — and we had further ij reports from other landholders around the same time of cattle on oat stubble being affected with suspected wooden tongue.

Histopathology reported Lymphadenitis, granulomatous, multifocal, chronic, and severe with intralesional Splendore-hoeppli material. Several animals had mild swelling of the tongue and reduced muscle tone Figure 7causing the tongue to protrude.
Response to treatment is generally good, but recurrence is common, particularly in chronic cases Actinobacillosia et al, Actinobacillus lignieresii was isolated from the lesions and identified by amplification, sequencing, and analysis of the 16S ribosomal r DNA gene. Lymphatic actinobacillosis is a frequent disease in Uruguay, southern Brazil, and Argentina.
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. The worst affected animals caattle standing with necks outstretched, drooling, with stridor and heavy breathing.
Rickettsia typhi Murine typhus Rickettsia prowazekii Epidemic typhusBrill—Zinsser diseaseFlying squirrel typhus. None were observed to have lesions within the oral cavity. Actinobaci,losis situation resolved to a point that affected animals were no longer easily identifiable in the paddock.
Natural lymphatic (“atypical”) actinobacillosis in cattle caused by Actinobacillus lignieresii.
Broad spectrum long acting antibiotics were a more feasible and practical option. We are unsure why the avtinobacillosis on the first property presented with the cutaneous form in this instance. 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.
Routine management advice was also given including recommendations to wormtest and drench if required. The injury results in different forms and locations of the disease depending on the location of the tissue.
Natural lymphatic (“atypical”) actinobacillosis in cattle caused by Actinobacillus lignieresii.
Enterotoxigenic Enteroinvasive Enterohemorrhagic O 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 a zoonotic disease caused by Actinobacillus. Rickettsia felis Flea-borne spotted fever. One of the most common forms seen by veterinarians is mouth actinobacillosis of cattledue to Actinobacillus lignieresii.
Anaplasma phagocytophilum Human granulocytic anaplasmosisAnaplasmosis Ehrlichia chaffeensis Human monocytotropic ehrlichiosis Ehrlichia ewingii Ehrlichiosis ewingii infection.
Exotic diseases that cause excessive salivation such as foot and mouth and bluetongue were also excluded based on clinical examination. On examination, the affected cows were found to have cm diameter granulomatous lesions in the submandibular region. 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.
