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

Affected cattle had elevated temperatures, ranging from The affected animals were treated with long acting oxytetracycline and removed from the oat crop. Journal of Veterinary Diagnostic Investigation. Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue.

Biochemistry on two affected animals showed one had a mild copper deficiency 7. Broad spectrum long acting antibiotics were a more feasible and practical option. On examination, the affected cows were found to have cm diameter cattpe lesions in the submandibular region. Rickettsia akari Rickettsialpox Orientia tsutsugamushi Scrub typhus.

It is more commonly associated with animals than with humans. 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.

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.

Biopsies collected from several animals were sent to EMAI for testing Figure 9 and returned a pure growth of 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. The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters. These soft tissues include subcutaneous tissues, the tongue, lymph nodes, lungs, and various tissues in the gastrointestinal tract.

The retropharyngeal and submaxillary lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al, By using this site, you agree to the Terms of Use and Privacy Policy. They had been vaccinated with 5 in 1 at weaning, and had not been recently wormed. Faecal testing for worm eggs revealed no significant worm burden.

Routine management advice was also given including recommendations to wormtest and drench if required. 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. One animal was observed to have a small 5cm diameter granulomatous mass under the tongue figure 8. Actinobacillosis, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals.

None were observed to have lesions within the oral cavity.

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, The histologic lesions were multifocal pyogranulomatous lymphadenitis, dermatitis, and catle with Splendore-Hoeppli material.

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.

We are unsure why the cattle on the first property presented with the cutaneous form in this instance. Actinobacillosis is a common diagnosis in cattle, but generally affects individual animals — it unusual to see such high numbers affected within a herd. Actinobacillus lignieresii was isolated from the lesions and identified by amplification, sequencing, and analysis of the 16S ribosomal r DNA gene.

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.

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. The injury results in different forms and ij of the disease depending on the location of the tissue. The most prominent symptom is the swelling of the tongue that protudes from the actinobacilloais and is very hard at palpation “wooden tongue”.

Brucellaceae Brucella abortus Brucellosis. In the following cases, signalment, diet and environmental conditions combined to cause outbreaks of the condition within these herds. Most affected animals also had some degree of subcutaneous oedema in the neck.

CASE NOTES

We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes of the head and neck. The eruption of teeth also commonly causes an entry point for the bacteria Jubb et al, 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.

Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. Actinobacillosis is a disease of soft tissue, spreading as a lymphangitis cagtle regional lymph nodes, differentiating it from actinomycosis, which causes bone lesions.

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. Salmonella enterica Typhoid feverParatyphoid feverSalmonellosis. The worst affected animals were standing with necks outstretched, drooling, with stridor and heavy cattoe. One of the most common forms seen by veterinarians is mouth actinobacillosis of cattledue to Actinobacillus lignieresii.

Seven of 8 cows recovered after treatment with sodium iodide. This page was last edited on 1 Octoberat
