Multiple plasmid origin‐of‐transfer regions might aid the spread of antimicrobial resistance to human pathogens

MicrobiologyOpen, Volume 9, Issue 12, December 2020., 2020
A structural alignment procedure developed here enables finding and typing plasmid‐borne origin‐of‐transfer substrates in large plasmid datasets. Thousands of putative DNA transfer substrates are identified, showing that plasmid mobility can be twofold higher and span almost twofold more host species than is currently known.

Surveying bovine digital dermatitis and non‐healing bovine foot lesions for the presence of Fusobacterium necrophorum, Porphyromonas endodontalis and Treponema pallidum

Veterinary Record, Volume 186, Issue 14, Page 450-450, April 2020., 2020
Background Non‐healing bovine foot lesions, including non‐healing white line disease, non‐healing sole ulcer and toe necrosis, are an increasingly important cause of chronic lameness that are poorly responsive to treatment. Recent studies have demonstrated a high‐level association between these non‐healing lesions and the Treponema phylogroups ...

Survival of the ovine footrot pathogen Dichelobacter nodosus in different soils [PDF]

Anaerobe, 2016
Dichelobacter nodosus (D. nodosus) is the causative agent of footrot in sheep; one of the most important health and welfare issues of sheep worldwide. For control programmes to be effective, it is essential that the transmission cycle of D. nodosus is understood and bacterial reservoirs in the environment are better defined.

Genetic organization of the duplicated vap region of the Dichelobacter nodosus genome [PDF]

Journal of Bacteriology, 1994
The recombinant plasmid pJIR318 contains a fragment of the Dichelobacter nodosus genome which is associated with virulence. Sequence analysis of the pJIR318 insert has shown that it contains four vap (virulence-associated protein) genes which are homologous to open reading frames found on the Escherichia coli F plasmid and the Neisseria gonorrhoeae ...

Molecular characterization of a genomic region associated with virulence in Dichelobacter nodosus [PDF]

Infection and Immunity, 1992
The major pathogen implicated in footrot, a highly contagious disease of sheep, is the strict anaerobe Dichelobacter nodosus (formerly Bacteroides nodosus). Sequence analysis of a 2,262-bp segment of the D. nodosus genome which is more prevalent in virulent isolates than in other isolates showed the presence of four open reading frames which appeared ...

Molecular Diagnosis of Footrot and Contagious Ovine Digital Dermatitis in Small Ruminants in the Iberian Peninsula

Animals
Contagious ovine digital dermatitis (CODD) and footrot (FR), a sub-acute or acute necrotic (decaying) infectious disease involving the hoof and underlying tissues, pose economic challenges to herds in Spain and worldwide. The aetiological agent for FR is

Land use and soil characteristics are associated with increased risk of treponeme‐associated hoof disease in elk

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Environments can shape the occurrence and extent of disease outbreaks in wildlife. We studied the effects of environmental features on the occurrence of treponeme‐associated hoof disease (TAHD), an emerging infectious disease of free‐ranging elk (Cervus canadensis), in southwestern Washington, USA.

Pixelated pathologies: Camera trapping as a tool for monitoring wildlife health

Journal of Applied Ecology, Volume 62, Issue 11, Page 2894-2913, November 2025.
Given the increasing emergence of diseases, some with conservation and public health implications, improving and expanding wildlife health surveillance strategies is imperative. Camera trapping is particularly relevant for detecting new outbreaks, monitoring high‐risk zones and evaluating risk mitigation measures. Abstract Camera trapping has become an

Natural Mycoplasma Infection Reduces Expression of Pro-Inflammatory Cytokines in Response to Ovine Footrot Pathogens

Animals, 2022
Ovine footrot is a complex multifactorial infectious disease, causing lameness in sheep with major welfare and economic consequences. Dichelobacter nodosus is the main causative bacterium; however, footrot is a polymicrobial disease with Fusobacterium ...

Footrot in sheep and goats: a case study

Australian Veterinary Journal, Volume 103, Issue 6, Page 330-331, June 2025.
This observational study highlights the apparent lower severity of footrot in goats compared with sheep, the risk of false negative results from elastase tests, the need to clean contractors' equipment between properties and indicates the potential use of kidding (or lambing) time and individual mob biosecurity in managing footrot.
