Antigens for serological diagnosis of ovine footrot

Veterinary Microbiology, 1997
An antigen extracted from Dichelobacter nodosus with potassium thiocyanate (KSCN) is currently used in enzyme-linked immunosorbent assay (ELISA) for serological diagnosis of ovine footrot, but the test lacks specificity in mature sheep. Other antigens were therefore evaluated for use in this test.

Current approaches to the management of ovine footrot

Veterinary Journal, 2005
Ovine footrot remains the most important cause of lameness in sheep flocks in the UK, despite the existence of proven methods for the control of the disease. Recent research suggests that sheep farmers may be unaware of these methods and may allocate greater resources to treatment of footrot rather than to its prevention.

Effectiveness of Vaccination in Controlling Ovine Footrot

Journal of Animal Science, 1989
Efficacy of reducing footrot by use of a commercial vaccine was evaluated over 2 yr with 223 ewes from five crossbred genotypes. Ewes were assigned randomly within genotype, age and initial footrot status to a 2 x 3 factorial array of vaccination in the 1st yr and fall vaccination, winter vaccination or control in the 2nd yr.

Treatment of virulent footrot with lincomycin and spectinomycin

Australian Veterinary Journal, 1990
SUMMARY A mixture of lincomycin and spectinomycin was investigated as a treatment for footrot in sheep. In a controlled clinical trial 92.5% of acute and chronic cases of virulent footrot were cured following a single intramuscular injection of a mixture containing 50 mg lincomycin and 100 mg spectinomycin/ml at a dose rate of 1 ml/10 kg bodyweight. No

Recombinant vaccines against ovine footrot

Immunology & Cell Biology, 1993
SummaryFor the past 20 years footrot vaccines have evolved from simple bacterins to highly specific recombinant DNA (rDNA) fimbrial vaccines. The development of these vaccines has left a trail of discoveries, challenges and solutions; these processes continue as we move closer to understanding the requirements of a footrot vaccine.

A role for DNA characterisation in ovine footrot

Australian Veterinary Journal, 1989
SUMMARY Bacteroides nodosus involved in several outbreaks of ovine footrot over a number of years were subjected to DNA restriction endonuclease analysis. Individual isolates were found to have characteristic Bam HI profiles which permitted their accurate identification and differentiation from other isolates. Bam HI profiles of B.

Reviewing Footrot in Sheep

2019
Ovine footrot is the main cause of lameness in sheep around the world and is responsible for extensive economic and welfare impacts. It can be an extremely contagious disease, resulting from the invasion of the interdigital tissue by a complex mixture of bacteria, in which Dichelobacter nodosus is a required component. Strains of D.

The bacteriology and histopathology of footrot in sheep

Australian Journal of Agricultural Research, 1962
Fusiformis nodosus was shown to cause severe footrot in sheep without the intervention of either, or both, of the other bacteria usually present in natural cases, namely, Treponema penortha and a motile fusiform bacillus. The progress of experimental infections in the sheep's foot with pure cultures of F.
