Bovine digital dermatitis (BDD) is an epidermitis which is a leading cause of infectious lameness. The only recognized diagnostic test is foot inspection, which is a labour-intensive procedure. There is no universally recognized, standardized lesion scoring system. As small lesions are easily missed, foot inspection has limited diagnostic sensitivi...
Article
Bovine digital dermatitis (BDD) is a debilitating infection that is being increasingly recognized in livestock worldwide. Several treponeme phylotypes have been identified in BDD lesions, although only a single BDD-associated treponeme taxon (Treponema brennaborense) has been proposed thus far. In a previous study, we observed that four BDD-associa...
Article
This study used a PCR-based approach targeting 16S rRNA gene fragments to determine the occurrence and association of the three bovine digital dermatitis (BDD) treponeme phylogroups within lesions found in cattle from the United Kingdom. Examination of 51 BDD lesions collected from infected cattle across the United Kingdom revealed that BDD trepone...
Article
Bovine digital dermatitis (BDD) is an infectious lameness in cattle, which has a large global impact in terms of animal welfare and cost. The majority of evidence suggests that spirochaetes are the aetiological agent of this disease. The aim of this study was to identify the susceptibility of BDD associated spirochaetes to a range of antimicrobial...
Article
The aim of this experimental study was to investigate the possible protective effect of dantrolene on neuronal injury induced by aortic ischemia/reperfusion (I/R). Nineteen rabbits were divided into three groups: sham (group 1, n = 5, no I/R), control (group 2, n = 7, only I/R) and dantrolene (group 3, n = 7, dantrolene + I/R). Abdominal aortic occ...
Article
Bovine digital dermatitis (BDD) is a severe infectious cause of lameness which has spread through dairy cattle populations worldwide, causing serious welfare and agricultural problems. Spirochetes are the main organisms implicated and have previously proven difficult to isolate. This study aimed to isolate and characterise the range of spirochetes...

There are several factors affecting the aggressiveness of animals and human beings, particularly abnormal serum lipid concentrations have been associated with aggression in humans, and were also scarcely reported in aggressive dogs. The possible link between serum lipid concentrations and degrees of aggression in MPD (military patrol dogs) trained...
Article
The aim of the study was to characterize a spirochaete isolated from the lesions of a cow with digital dermatitis (DD). The characterization was on the basis of its light and electron microscopic appearance, enzymic profile and DNA sequence analysis of its flagellin and 16S rRNA genes. The spirochaete was 6-8-microm long and 0.2-0.3 microm in diame...
Article
A potential pathological role for spirochaetes in bovine digital dermatitis (bovine DD) and severe virulent ovine foot rot (SVOFR) has been considered and a treponeme isolate obtained from each disease in the UK. In this work, we have investigated the hypothesis that the two diseases may have a shared (common) spirochaetal aetiology. Experiments we...
Article
In this study, it was aimed to examine the urinary system and to determine normal ultrasonographic appearance by rectal ultrasonography in Holstein cows. The study material consisted of 20 bladders, 20 urethras, and 20 right and 20 left kidneys, in 20 Holstein cows. A portable ultrasonograph combined with a 6 MHz linear rectal probe (transducer) wa...
Article
Bovine digital dermatitis causing lameness in a dairy herd in Turkey is described. The lesions were similar to those described for Mortellaro disease. Inflammation of the skin was mostly located at the plantar aspect of the foot, just above the interdigital cleft, and resembled strawberry-coloured epidermal erosion, which was prone to bleed when vi...
