Bovine actinobacillosis is typically characterized by pyogranulomatous glossitis (wooden tongue). The involvement of other tissues, generally the skin or lymph nodes, has been regarded as atypical or cutaneous. We describe herein 2 outbreaks of actinobacillosis affecting primarily the lymph nodes...

We report an unusual case of actinobacillosis in four 8-15 month heifers and 2 dairy cows from 190 Holstein cattle with history feeding on oat and wheat straw due to 4 years of drought. In heifers we found cud dropping, drooling, reduced rumination, anorexia, swelling of parotid and...

Over a period of one year, 8 young beef cows out of a total of 160 showed cutaneous lesions on their hind limbs. Histopathology and bacteriology of biopsies allow the diagnosis of actinobacillosis with the isolation of Actinobacillus lignieresii. The descriptive, diagnostic and therapeutic steps...

Actinobacillosis usually is a sporadic infection that affects the tongue in cattle ("wooden tongue") with possible spread to the digestive tract. Two 4-year-old Rouge-des-Prés cows from a single French beef herd were referred for chronic (2-6 months) swelling and cutaneous nodules in the distal...

Avian haemolytic Actinobacillus-like organisms have tentatively been named Bisgaard taxon 26. Phenotypic information has been published on 65 strains of this taxon. In the current study, 31 isolates were selected for genotypic characterization. Thirty strains had the same rpoB sequence and only one ...

The aetiology, epidemiology, clinical signs and differential diagnosis of lumpy skin disease in 7 cattle in England and Wales, UK, in 24 May 2016 are presented. Biopsy samples showed severe pyogranulomatous dermatitis caused by Actinobacillus lignieresii in a steer, lymphoma in 2 cows and...

Actinobacillosis is an infectious, chronic, generally non-fatal disease caused by Actinobacillus lignieresii. The etiologic agent is a part of the oral flora and causes pyogranulomatous lesions of the soft tissues. A 5-year old, approximately 500 kg cross-breed Holstein cow was presented for the...

Post-mortem findings in cattle and pigs detected at slaughter houses in Finland are reviewed. The following findings are discussed: bovine lymphoma, E. coli infection causing calf diarrhoea and bovine pulmonary embolism, bacterial granulomas, botryomycosis caused by Pseudomonas aeruginosa in...

In February 1997, several cows from a herd of 115 commercial crossbred beef cows in Florida, USA, were observed to have swelling at the angle of mandible. Samples of exudate obtained by aspiration were confirmed as containing Actinobacillus lignieresii. Affected cows were treated with i.v. sodium...

An unusual occurrence of actinobacillosis was diagnosed in 4 heifers aged 8-15 months and 2 cattle in a dairy herd with 190 Iranian Holstein breed. Anorexia, dysphagia, drooling of normal or foodtinged saliva and presence of warts-like lesions on the dorsal surface of tongue shaft were observed in...
