Dichelobacter nodosus, Fusobacterium necrophorum and the epidemiology of footrot
Anaerobe, 2009Footrot is a debilitating disease of sheep resulting in lameness, production losses and suffering. To study the basic bacteriology of the disease, a survey was initiated across commercial farms and non-commercial research flocks to compare the bacteriology of symptomatic footrot infected sheep with healthy asymptomatic sheep.

Characterisation of Dichelobacter nodosus isolates from Norway
Veterinary Microbiology, 2013An outbreak of ovine footrot in Norway in 2008, the first reported since 1948, prompted action to investigate Norwegian isolates of Dichelobacter nodosus. A total of 579 isolates from 124 different farms were characterised. These included 519 isolates from sheep, 52 isolates from cattle and 8 isolates from goats. The potential virulence of the isolates

Transformation-mediated serogroup conversion of Dichelobacter nodosus
Veterinary Microbiology, 2003Dichelobacter nodosus is the essential causative agent of footrot in sheep. The type IV fimbriae of D. nodosus are required for virulence, are highly immunogenic and immunoprotective, and can be divided into 10 major serogroups. Fimbrial variation has been postulated to have arisen because of genetic recombination within the fimbrial gene region ...

The laboratory culture of Dichelobacter nodosus in a footrot eradication program
Australian Veterinary Journal, 1994As part of a program to eradicate virulent footrot from Western Australia, 2745 isolates of Dichelobacter nodosus were isolated from 5263 specimens from 1883 submissions. The virulence of each isolate was assessed using protease thermostability and isoenzyme zymogram.

Identification of two new Dichelobacter nodosus strains in Germany
The Veterinary Journal, 2010The multi-strain anaerobe Dichelobacter nodosus causes footrot, a contagious disease of the digits of ruminants that occurs worldwide. Eleven D. nodosus-like isolates from footrot lesions of sheep in Germany were investigated by PCR amplification of the variable region of the D. nodosus fimbrial (fimA) gene.

Identification and Characterization of a Native Dichelobacter nodosus Plasmid, pDN1
Plasmid, 2000The gram-negative anaerobe Dichelobacter nodosus is the primary causative agent of ovine footrot, a mixed bacterial infection of the hoof. We report here the characterization of a novel native plasmid, pDN1, from D. nodosus. Sequence analysis has revealed that pDN1 has a high degree of similarity to broad-host-range plasmids belonging, or related, to ...

Sequencing and expression of the aroA gene from Dichelobacter nodosus
Gene, 1994The aroA locus of the Gram- pathogen Dichelobacter nodosus, which encodes 5-enolpyruvylshikimate 3-phosphate (EPSP) synthase, has been sequenced and expressed in Escherichia coli. The gene is located on a 1.48-kb DraI-HindIII fragment located directly upstream and in opposite transcriptional orientation to the gene encoding the fimbrial structural ...

A gene region in Dichelobacter nodosus encoding a lipopolysaccharide epitope
Microbiology, 1995Dichelobacter nodosus is a Gram-negative anaerobic bacterium that is the causative organism of footrot in sheep. A D. nodosus locus responsible for a modification of the host lipopolysaccharide (LPS) in Escherichia coli was cloned and sequenced. Genetic studies showed that the modification occurred within the inner-core region of the host LPS, most ...

Fusobacterium necrophorum, and not Dichelobacter nodosus, is associated with equine hoof thrush
Veterinary Microbiology, 2013The aim of this study was to determine which of the two species, Fusobacterium necrophorum or Dichelobacter nodosus, are associated with hoof thrush in horses. Fourteen hoof samples, collected from eight horses with thrush and 14 samples collected from eight horses with healthy hooves, were examined for the presence of F.
