Journal ArticleDOI
Biosecurity in pig farms: a review
TL;DR: In this article, a review of external and internal biosecurity measures that reduce risks in swine production and the relationship between these measures and the epidemiology of the main diseases is presented.
Journal ArticleDOI
The Spirochete Brachyspira pilosicoli, Enteric Pathogen of Animals and Humans.
TL;DR: Clinicians and clinical microbiologists are encouraged to consider B. pilosicoli in their differential diagnoses and to develop and use appropriate diagnostic protocols to identify the spirochete in clinical specimens.
Journal ArticleDOI
Postweaning mortality in commercial swine production II: review of infectious contributing factors.
Jordan T. Gebhardt,Michael D. Tokach,Steve S Dritz,Joel M. DeRouchey,Jason C Woodworth,Robert D. Goodband,Steve C Henry +6 more
TL;DR: Since there are many infectious agents and noninfectious contributors, emphasis should continue to be placed on those infectious agents with the greatest impact to minimize postweaning mortality.
Journal ArticleDOI
Etiology of Colitis-Complex Diarrhea in Growing Pigs: A Review.
TL;DR: The exact etiology of CCD is still unclear; however, pathogens including Brachyspira (B.) hyodysenteriae, B. pilosicoli, and swine whipworms such as Trichuris (T.) suis have been involved in specific colitis (SC).
Journal ArticleDOI
An atypical weakly haemolytic strain of Brachyspira hyodysenteriae is avirulent and can be used to protect pigs from developing swine dysentery
TL;DR: Data indicate that MU1 lacks virulence and has potential to be used to help protect pigs from SD and that weakly haemolytic B. hyodysenteriae strain D28 from Belgium failed to cause disease when used experimentally to infect pigs.

Serpulina pilosicoli sp. nov., the Agent of Porcine Intestinal Spirochetosis
Darren J. Trott,Thaddeus B. Stanton,Neil S. Jensen,Gerald E. Duhamel,John L. Johnson,David J. Hampson +5 more
TL;DR: DNA-DNA relative reassociation experiments in which the S1 nuclease method was used revealed that intestinal spirochete strain P43/6/78T was related to, but was genetically distinct from, both S. hyodysenteriae B78T and S. innocens B256T, and it is proposed that strain P 43/ 6/78 should be designated as the type strain of a new species, Serpulina pilosicoli.
Journal ArticleDOI
Changes in Bacterial Community Structure in the Colon of Pigs Fed Different Experimental Diets and after Infection with Brachyspira hyodysenteriae
TL;DR: When the animals were experimentally infected with Brachyspira hyodysenteriae, causing swine dysentery, many of the T-RFs fluctuated, suggesting a destabilization of the microbial community.
Journal ArticleDOI
Treponema innocens, a New Species of Intestinal Bacteria, and Emended Description of the Type Strain of Treponema hyodysenteriae Harris et al.
Joann M. Kinyon,D. L. Harris +1 more
TL;DR: Two nonpathogenic types of treponemes isolated from pigs and dogs are regarded as belonging to a new species, Treponema innocens, and an emended description of strain B78, the type strain of T. hyodysenteriae is presented.
Journal ArticleDOI
Production of diarrhoea and dysentery in pigs by feeding pure cultures of a spirochaete differing from Treponema hyodysenteriae.
DJ Taylor,JR Simmons,HM Laird +2 more
TL;DR: A weakly beta-haemolytic spirochaete, isolate P43/6/78, was isolated from a pig with diarrhoea and found not to fluoresce with a specific fluorescent antiserum to Treponema hyodysenteriae, and was considered to belong to a species other than T hyodysteriae.
Journal ArticleDOI
Phenotypical characterisation of intestinal spirochaetes isolated from pigs.
Claes Fellström,A. Gunnarsson +1 more
TL;DR: A combined evaluation of the phenotypical properties of five Serpulina type or reference strains and 163 Swedish isolates of spirochaetes from pigs and two from birds was made, finding that there was a statistical relationship between pigs with diarrhoea and the isolation of group IV spirochametes but no relationship with group III spiroCHAetes.
