Brachyspira hyodysenteriae in apparently healthy pig herds

Veterinary Record, 2018
The spirochaete Brachyspira hyodysenteriae causes swine dysentery, a potentially severe mucohaemorrhagic colitis of pigs that is endemic in many countries. Swine dysentery depresses growth, and can cause disruptions to pig trade and potential litigation if herds supplying replacement animals are infected.

Immunomagnetic separation of the intestinal spirochaetes Brachyspira pilosicoli and Brachyspira hyodysenteriae from porcine faeces

Journal of Medical Microbiology, 2004
Porcine intestinal spirochaetes are fastidious anaerobic organisms and, as a consequence, it has been necessary to develop various protocols to enhance their isolation from or detection in faeces. Immunomagnetic separation (IMS) is a method developed recently to improve separation of target cells from mixed cell suspensions.

Survival of Brachyspira hyodysenteriae and B. pilosicoli in terrestrial microcosms

Veterinary Microbiology, 2001
The survival of Brachyspira hyodysenteriae and Brachyspira pilosicoli was investigated at 10 degrees C in laboratory microcosms consisting of soil, porcine faeces, and in soil mixed with 10% porcine faeces, respectively. By plate spreading, survival of B.

Antimicrobial susceptibility testing of Spanish field isolates of Brachyspira hyodysenteriae

Research in Veterinary Science, 2009
This study is the first conducted in Spain to evaluate antimicrobial susceptibility of field isolates of Brachyspira hyodysenteriae. One hundred and eight isolates of the bacterium, recovered from different Spanish swine farms between 2000 and 2007, were investigated.

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
