Experimental infection of cattle with ovine Dichelobacter nodosus isolates. [PDF]

Acta Vet Scand, 2015
Dichelobacter nodosus is the main causative agent of ovine footrot, and there are strong indications that the bacterium can be transferred to cattle grazing on the same pasture as sheep. The aim of this study was to investigate if benign and virulent D.

An infectious disease outbreak and increased mortality in wild alpine reindeer

Ecosphere, Volume 14, Issue 3, March 2023., 2023
Abstract Climate changes may lead to tipping points where the epidemiological characteristics of infectious wildlife diseases suddenly change, leading to outbreaks. However, empirically documented cases of the extent to which emerging infectious diseases (EIDs) affect populations of large vertebrates are few, partly because of the limited surveillance ...

Contamination of bacterial extracellular vesicles (bEVs) in human urinary extracellular vesicles (uEVs) samples and their effects on uEVs study

Journal of Extracellular Biology, Volume 1, Issue 12, December 2022., 2022
Abstract Bacterial overgrowth is common for improperly stored urine. However, its effects on human urinary extracellular vesicles (uEVs) study had not been previously examined nor documented. This study investigated the presence of bacterial EVs (bEVs) contaminated in uEVs samples and their effects on uEVs study.

Assessment of animal diseases caused by bacteria resistant to antimicrobials: sheep and goats

EFSA Journal, Volume 19, Issue 12, December 2021., 2021
Abstract In this opinion, the antimicrobial‐resistant bacteria responsible for transmissible diseases that constitute a threat to the health of sheep and goats have been assessed. The assessment has been performed following a methodology based on information collected by an extensive literature review and expert judgement.

Ad hoc method for the assessment of animal diseases caused by bacteria resistant to antimicrobials

EFSA Journal, Volume 19, Issue 6, June 2021., 2021
Abstract The European Commission requested EFSA assess antimicrobial‐resistant bacteria responsible for animal transmissible diseases, with a view to listing such pathogens for European Union action. This Scientific Opinion addresses the ad hoc method developed: (i) to give a global state of play as regards resistant animal pathogens that cause ...

Novel inflammatory cell infiltration scoring system to investigate healthy and footrot affected ovine interdigital skin [PDF]

PeerJ, 2018
Ovine footrot is a degenerative disease of sheep feet leading to the separation of hoof-horn from the underlying skin and lameness. This study quantitatively examined histological features of the ovine interdigital skin as well as their relationship with

Gamithromycin in swine: Pharmacokinetics and clinical evaluation against swine respiratory disease

Veterinary Medicine and Science, Volume 7, Issue 2, Page 455-464, March 2021., 2021
Intramuscular injection of gamithromycin 15% w/v in swine at 6 mg/kg is characterized by rapid absorption and distribution to tissues. Clinical evaluation in an European field study incorporating 305 swine has shown safe and efficacious treatment for swine with bacterial respiratory disease. Abstract The pharmacokinetics of gamithromycin were evaluated

Delineation of the virulence-related locus (vrl) of Dichelobacter nodosus [PDF]

Microbiology, 1995
Dichelobacter nodosus is the primary pathogen implicated in ovine footrot. In this paper we have delineated a 27 kb locus, termed the virulence-related locus (vrl), that was essentially specific for virulent D. nodosus isolates. The precise ends of this locus were mapped and the sequences of the junction regions from the virulent strain A198 were ...

Twitching motility is essential for virulence in Dichelobacter nodosus. [PDF]

J Bacteriol, 2008
ABSTRACT Type IV fimbriae are essential virulence factors of Dichelobacter nodosus , the principal causative agent of ovine foot rot. The fimA fimbrial subunit gene is required for virulence, but fimA mutants exhibit several phenotypic changes and it is not ...

Glycosylation of type-IV fimbriae of Dichelobacter nodosus

Veterinary Microbiology, 2008
Dichelobacter 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
