Potential transmission routes of Dichelobacter nodosus
Veterinary Microbiology, 2018Footrot caused by Dichelobacter nodosus is a highly contagious bacterial disease affecting the claw of sheep and the main cause of lameness in these animals. It is not only an economic burden but also a serious animal welfare issue. More information about the transmission of D. nodosus is needed for effective footrot control programs.

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 ...

Glycosylation of type-IV fimbriae of Dichelobacter nodosus
Veterinary Microbiology, 2008Dichelobacter nodosus is the causative agent of ovine footrot and the type-IV fimbriae on this bacterium are essential for maintaining its virulence. In this study, we reveal that these fimbriae are glycosylated. This was demonstrated in several ways: by the detection of carbohydrate on fimbrial protein using periodic acid Schiff reagent (PAS) staining

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.

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.

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 ...

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 ...
