Actinobacillosis – Wikipedia

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.

Brucellaceae Brucella abortus Brucellosis. Some were open with a bloody or purulent discharge See figure 5while others were closed, with no sign of external injury. The retropharyngeal and submaxillary lymph nodes are most commonly affected, which causes dysphagia and dyspnoea Jubb et al, In catrle following cases, signalment, diet and environmental conditions combined to cause outbreaks of the condition within these herds. From Wikipedia, the free encyclopedia.


Retrieved 7 October A diagnosis of wooden tongue was made based actinobwcillosis clinical signs, and the affected cows were treated with a single long acting Oxytetracycline injection. Actinobacillosis is a zoonotic disease caused by Actinobacillus.

Parkinson et al actinobacillosjs 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 the lingual groove. Multiple animals had large nodular masses evident, predominantly actinnobacillosis 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, or Wooden Tongue is not an uncommon condition in cattle, but is generally seen sporadically in individual animals. The bacteria is reported to survive for up to 5 days in the environment Radostitis et al,therefore in both actimobacillosis it was recommended that affected cattle be removed from the rest of the herd to avoid further contamination of the paddock and feed bins.


Biochemistry on two affected animals showed one had a mild copper deficiency 7. This page was last edited on 1 Octoberat Faecal testing for worm eggs revealed no significant worm burden.

Retrieved from ” https: 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.

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. Rickettsia akari Rickettsialpox Orientia tsutsugamushi Scrub typhus. The histologic lesions were multifocal pyogranulomatous lymphadenitis, dermatitis, and cellulitis with Splendore-Hoeppli material. Broad spectrum long acting antibiotics were a more feasible and practical option.

Enterotoxigenic Enteroinvasive Enterohemorrhagic O Actinobacillosis is a disease of soft tissue, spreading as a lymphangitis involving regional lymph nodes, differentiating it from actinomycosis, which causes bone lesions. Vibrio cholerae Cholera Vibrio vulnificus Vibrio parahaemolyticus Vibrio actinobacilosis Plesiomonas shigelloides.

Histopathology reported Lymphadenitis, granulomatous, multifocal, chronic, and severe with intralesional Splendore-hoeppli material.

The eruption of teeth also commonly causes an entry point for the bacteria Jubb et al, Most affected animals also had some degree of subcutaneous oedema in the neck.


The situation resolved to a point that affected animals were no longer easily identifiable in the paddock. It is more commonly associated with animals than with humans. Later, lesions may extend to the subcutaneous tissue and the skin, causing ulceration. It does not spread readily unless predisposing environmental conditions cause a high incidence of oral lacerations Radostits et al, 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 actinobaciplosis investigating these cases.

Anaplasma phagocytophilum Human granulocytic anaplasmosisAnaplasmosis Ehrlichia chaffeensis Human monocytotropic ehrlichiosis Ehrlichia ewingii Ehrlichiosis ewingii infection. Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis wooden tongue. The recommended treatment of sodium iodide was prohibitively expensive in these cases.


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. Affected cattle had elevated temperatures, ranging from The injury results in different forms and locations of the disease depending on the location of the tissue.

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.

Journal of Veterinary Medicine, Series A. The infection is most commonly caused by abrasions on different soft tissues through which the bacteria, Actinobacillus lignieresii, enters.

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.

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

Actinobacillus lignieresii was isolated from the lesions and identified by amplification, sequencing, and analysis of the 16S ribosomal r DNA gene. We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes of the head and neck.

They had been vaccinated with 5 in 1 at weaning, and had not been recently wormed. The involvement cartle other tissues, generally the skin or lymph nodes, has been regarded as atypical or cutaneous.

Examination of the worst affected animals showed large, firm granulomatous masses in predominantly submandibular locations.

Antibiotic sensitivity testing of the cultured bacteria revealed sensitivity to a range of common antibiotics including tetracyclines.
