Distribution and transmission of aetiological agents of swine dysentery

The presence of strong haemolysis on the isolation plate signals that the spirochaete species is pathogenic; however, weakly haemolytic isolates of B hyodysenteriae have also been reported. 6,14 Rohde and others 3 found that MALDI-TOF mass spectrometry analysis of their isolates did not give a definitive identity for B suanatina, probably because of the limited data available for this species in the database used. Strongly haemolytic Brachyspira species on an isolation plate Brachyspira spirochetes are helical shaped bacteria with regular coiling patterns Finally, where pigs have access to outdoors areas they should be considered to be at increased risk of exposure to pathogens, including Brachyspira species. First isolation of "Brachyspira hampsonii" from pigs in Europe. First identification of "Brachyspira hampsonii" in wild European waterfowl.
