One of the most common forms seen by veterinarians is mouth actinobacillosis of cattledue to Actinobacillus lignieresii. 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. One animal was observed to have a small 5cm diameter granulomatous mass under the tongue figure 8.
Actinobacillosis – Wikipedia
Enterotoxigenic Enteroinvasive Enterohemorrhagic O Klebsiella pneumoniae RhinoscleromaKlebsiella pneumonia Klebsiella granulomatis Granuloma inguinale Klebsiella oxytoca Escherichia coli: Actinobacillosis is not considered a high risk zoonotic disease, but catle organism has been isolated from bite wounds inflected by cattle Radostits et al,so care should be taken when investigating these cases.
The retropharyngeal and catgle lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al, The situation resolved to a point that affected animals were no longer easily identifiable in the paddock.
The cattle were aged years and had been grazing oat stubble for the past three weeks, during which time the problem had noticeably worsened. Retrieved from ” https: Salmonella enterica Typhoid feverParatyphoid feverSalmonellosis. They had been vaccinated with 5 in 1 at weaning, and had not been recently wormed. A diagnosis of wooden tongue was made based on clinical signs, and the affected cows were treated with a single long acting Oxytetracycline injection. These soft tissues include subcutaneous tissues, the tongue, lymph actinobackllosis, lungs, and various tissues in the xattle tract.
Actinobacillosis is a zoonotic disease caused by Actinobacillus. Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue. Brucellaceae Brucella abortus Brucellosis. 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.
adtinobacillosis Abbatoir surveys suggest that subclinical infections are common, particularly affecting the draining lymph cattl of the head Radostits et al Six months later on a actinibacillosis property at Burren Junction, 15 Angus x Hereford cows in a mob of 40 with calves at foot were observed with similar lesions.
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.
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.
Actinobacillosis, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals. Exotic diseases that cause excessive salivation such as foot and mouth and bluetongue were also excluded based on clinical examination.
Actinobacillosis is a common diagnosis in cattle, but generally affects individual animals — it unusual to see such high numbers affected within a herd. Broad spectrum actinnobacillosis acting antibiotics were a more feasible and practical option.
Affected cattle had elevated temperatures, ranging actjnobacillosis The injury results in different forms and locations of the disease depending on the location of the tissue. Pseudomonas aeruginosa Pseudomonas infection Moraxella catarrhalis Acinetobacter baumannii. The histologic lesions were multifocal pyogranulomatous lymphadenitis, dermatitis, and cellulitis with Splendore-Hoeppli material.
The recommended treatment of sodium iodide was prohibitively expensive in these cases. It is more commonly associated with animals than with humans. The eruption of teeth also commonly causes an entry point for the bacteria Jubb et al, Rickettsia typhi Murine typhus Rickettsia prowazekii Epidemic typhusBrill—Zinsser diseaseFlying squirrel typhus. Most broad spectrum antibiotics are effective Parkinson et al,and sensitivity testing confirmed that tetracyclines were actinonacillosis to be effective against the actinobacillosis agent in this case.
Parkinson et al reports a higher incidence of disease in cattle feeding on crops with awns, such as oats, and Jubb et al reports that the common primary lesion is caused by grass seeds and awns stuck in cqttle lingual groove. 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, Examination of the worst affected animals showed large, firm granulomatous masses in predominantly submandibular locations.
Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. Response to treatment is generally good, but recurrence is common, particularly in chronic cases Radostits et al, Biochemistry on two affected animals showed one had a mild copper deficiency 7.
The masses ranged from cm diameter, and were not attached to bone.
