Electroporation-mediated transformation of the ovine footrot pathogenDichelobacter nodosus [PDF]

FEMS Microbiology Letters, 1998
Studies on the potential virulence genes of the ovine footrot pathogen Dichelobacter nodosus have been hindered by the lack of a genetic system for this organism. In an attempt to accomplish the transformation of D. nodosus cells, we constructed a plasmid that contained part of a native D. nodosus plasmid and carried a tetracycline resistance gene that

The subtilisin-like protease AprV2 is required for virulence and uses a novel disulphide-tethered exosite to bind substrates. [PDF]

PLoS Pathogens, 2010
Many bacterial pathogens produce extracellular proteases that degrade the extracellular matrix of the host and therefore are involved in disease pathogenesis. Dichelobacter nodosus is the causative agent of ovine footrot, a highly contagious disease that

Molecular detection and characterization of Dichelobacter nodosus in ovine footrot in India

Molecular and Cellular Probes, 2004
Dichelobacter nodosus was detected in three clinical cases of ovine footrot in Kashmir, India. The detection was done by PCR in three clinical specimens directly, without isolating the organism, using species-specific 16S rDNA primers. Positive results were indicated by amplification of a 783 bp product.

A two-component regulatory system modulates twitching motility in Dichelobacter nodosus [PDF]

Veterinary Microbiology, 2015
Dichelobacter nodosus is the essential causative agent of footrot in sheep and type IV fimbriae-mediated twitching motility has been shown to be essential for virulence. We have identified a two-component signal transduction system (TwmSR) that shows similarity to chemosensory systems from other bacteria.

Bacterial species associated with interdigital phlegmon outbreaks in Finnish dairy herds

BMC Veterinary Research, 2019
Background Severe outbreaks of bovine interdigital phlegmon (IP) have occurred recently in several free stall dairy herds in Finland. We studied the aetiology of IP in such herds, and the association of bacterial species with the various stages of IP and

A Novel 3D Skin Explant Model to Study Anaerobic Bacterial Infection

Frontiers in Cellular and Infection Microbiology, 2017
Skin infection studies are often limited by financial and ethical constraints, and alternatives, such as monolayer cell culture, do not reflect many cellular processes limiting their application.

Genetic Variability and Antibacterial Sensitivity of Dichelobacter nodosus and Fusobacterium necrophorum Infection in Sheep Sulaimani Province, Kurdistan Region, Iraq

The Iraqi Journal of Veterinary Medicine
Footrot is a significant health problem in ruminants, especially sheep, caused by the bacteria Dichelobacter nodosus and Fusobacterium necrophorum. Infected animals may become lame and lose body condition.

Isolation and molecular characterization of Dichelobacter nodosus isolated from sheep in Brazil

Acta Scientiae Veterinariae, 2018
Background: Pododermatitis or footrot is an infectious disease that affects the hoof and interdigital tissue of sheep causing lameness. The disease is caused by the interaction of the agent Dichelobacter nodosus and symbiotic bacteria in the complex environment of the epidermal tissues of the hoof and host immune system. D.
