Occurrence of Brachyspira hyodysenteriae in multiplier pig herds in Switzerland

Tierärztliche Praxis Ausgabe G: Großtiere / Nutztiere, 2016
SummaryObjective: This research was aimed to determine the occurrence of Brachyspira (B.) hyodysenteriae in Swiss multiplier pig herds. Materials and methods: In a pilot study a direct real-time polymerase chain reaction (PCR) method for B. hyodysenteriae was compared to culture followed by PCR on 106 samples from three herds.

Risk factors for the infection with Brachyspira hyodysenteriae in pig herds

Preventive Veterinary Medicine, 2020
Swine dysentery (SD), caused by infection with Brachyspira hyodysenteriae, is a serious disease in pig production worldwide. Quantitative risk factors triggering the occurrence of infection are unknown. The present case-control study aimed at identifying major risk factors related to presence of B. hyodysenteriae in pig herds.

Antimicrobial susceptibility of Brachyspira hyodysenteriae isolated from 21 Polish farms

Polish Journal of Veterinary Sciences, 2012
Swine dysentery (SD) is a common disease among pigs worldwide, which contributes to major production losses. Antimicrobial susceptibility testing of B. hyodysenteriae, the etiological agent of SD, is mainly performed by the agar dilution method. This method has certain limitations due to difficulties in interpretation of results.

[Multiresistant Brachyspira hyodysenteriae in a Dutch sow herd].

Tijdschrift voor diergeneeskunde, 2008
This case study describes the isolation ofa multiresistant strain ofBrachyspira hyodysenteriae in April 2007 in a Dutch sow herd with recurrent diarrhoea. Examination of faecal samples taken from 7-month-old breeding gilts with diarrhoea revealed the presence of resistance against tiamulin, lincomycin, tylosin, doxycycline, and tylvalosin (the active ...

Characterisation of multiresistant Brachyspira hyodysenteriae isolates from Czech pig farms

Veterinary Record, 2011
The aim of the present study was to evaluate the importance of clonal spread of Brachyspira hyodysenteriae resistant to pleuromutilins (tiamulin, valnemulin) on farms in the Czech Republic. Agar dilution method and macrorestriction fragment profile analysis by pulsed field gel electrophoresis

Comparison of culture and biochemical tests with PCR for detection of Brachyspira hyodysenteriae and Brachyspira pilosicoli

Journal of Microbiological Methods, 2006
Traditional culture and biochemical tests (CBT) were compared with PCR for sensitivity and detection of Brachyspira hyodysenteriae and Brachyspira pilosicoli in seeded faeces and clinical samples from diarrhoeic pigs. A duplex PCR system was developed based on primers detecting the tlyA-gene of B. hyodysenteriae and the 16S rRNA-gene of B.

Transposon-associated lincosamide resistance lnu(C) gene identified in Brachyspira hyodysenteriae ST83

Veterinary Microbiology, 2018
Treatment of Swine Dysentery (SD) caused by Brachyspira hyodysenteriae (B. hyodysenteriae) is carried out using antimicrobials such as macrolides, lincosamides and pleuromutilins leading to the selection of resistant strains. Whole genome sequencing of a multidrug-resistant B.

SmpB: A novel outer membrane protein present in some Brachyspira hyodysenteriae strains

Veterinary Microbiology, 2006
A novel outer membrane protein-encoding gene was identified in Brachyspira hyodysenteriae. The predicted protein, SmpB, was encoded by a gene that contains regions of identity with that encoding the previously identified lipoprotein SmpA. However, the majority of the reading frame encoding SmpA and SmpB share no detectable similarity.

Experimental Challenge of Mallards (Anas platyrhynchos) with Brachyspira hyodysenteriae and “Brachyspira suanatina” Isolated from Pigs and Mallards

Journal of Comparative Pathology, 2009
Brachyspira hyodysenteriae, the aetiological agent of swine dysentery, and a recently proposed and closely related enteropathogenic spirochaete "Brachyspira suanatina", originally isolated from pigs or mallards (Anas platyrhynchos), were used to inoculate week-old mallard ducklings orally or cloacally.
