Social Structure of Sheep Flocks at Points of the Production Cycle and Relationship to Disease Spread, Using a Simulated Epidemic of Footrot [PDF]

Animals
Footrot is one of the top five globally important diseases of sheep and causes lameness, leading to poor welfare and productivity. Transmission of Dichelobacter nodosus, the causative agent, occurs via surfaces such as pasture or bedding and persistence ...

The prevalence of Dichelobacter nodosus in clinically footrot-free sheep flocks: a comparative field study on elimination strategies [PDF]

BMC Veterinary Research, 2020
Background Ovine footrot caused by Dichelobacter nodosus (D nodosus) is an infectious disease affecting sheep worldwide. Switzerland plans a nationwide footrot eradication program, based on PCR-testing of interdigital swab samples.

Standardization of Loop mediated isothermal amplification for detection of D. nodosus and F. necrophorum causing footrot in sheep and goats [PDF]

, 2021
Abstract The Loop Mediated Isothermal Amplification (LAMP) was standardized for rapid detection of D. nodosus and F. necrophorum. A total of 250 foot swabs (200) were screened from sheep and (50) were from goats from different districts of Rayalaseema viz., Chittoor, Nellore, Kadapa, Anantapur.

Characterisation of Dichelobacter nodosus on Misshapen and Damaged Ovine Feet: A Longitudinal Study of Four UK Sheep Flocks

Animals, 2021
Dichelobacter nodosus is the causal agent of ovine footrot, a contagious disease of welfare and economic concern worldwide. Damaged feet may be subclinical carriers of D. nodosus and covertly spread infection.

Nucleotide Sequence of the Pilin Gene of Bacteroides nodosus 340 (Serogroup D) and Implications for the Relatedness of Serogroups [PDF]

Microbiology, 1988
The gene encoding pilin of Bacteroides nodosus 340 has been isolated and the nucleotide sequence determined. The gene is present as a single copy within the B. nodosus genome and a protein of Mr 16683 can be predicted from the proposed coding region. A comparison of the predicted amino acid sequence with pilin from other strains of B. nodosus indicated

The role of the environment in transmission of Dichelobacter nodosus between ewes and their lambs [PDF]

, 2015
Dichelobacter nodosus (D. nodosus) is the essential causative agent of footrot in sheep. The current study investigated when D. nodosus was detectable on newborn lambs and possible routes of transmission. Specific qPCR was used to detect and quantify the

Multiple locus VNTR analysis highlights that geographical clustering and distribution of Dichelobacter nodosus, the causal agent of footrot in sheep, correlates with inter-country movements [PDF]

, 2013
Dichelobacter nodosus is a Gram-negative, anaerobic bacterium and the causal agent of footrot in sheep. Multiple locus variable number tandem repeat (VNTR) analysis (MLVA) is a portable technique that involves the identification and enumeration of ...

The AprV5 subtilase is required for the optimal processing of all three extracellular serine proteases from Dichelobacter nodosus. [PDF]

PLoS ONE, 2012
Dichelobacter nodosus is the principal causative agent of ovine footrot and its extracellular proteases are major virulence factors. Virulent isolates of D. nodosus secrete three subtilisin-like serine proteases: AprV2, AprV5 and BprV.
