| a novel enteropathogenic, strongly haemolytic spirochaete isolated from pig and mallard, provisionally designated 'brachyspira suanatina' sp. nov. | atypical, strongly haemolytic porcine isolates of intestinal spirochaetes differing genetically from brachyspira hyodysenteriae were identified and characterized. the isolates were subjected to culture and biochemical tests, antimicrobial susceptibility testing and molecular analyses. none of four species-specific polymerase chain reaction systems targeting genes of b. hyodysenteriae gave a positive reaction. all the atypical porcine isolates were identical in their partial 16s rrna and nox gene ... | 2007 | 17359270 |
| experimental challenge of mallards (anas platyrhynchos) with brachyspira hyodysenteriae and "brachyspira suanatina" isolated from pigs and mallards. | 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. the colonization rate, clinical outcome, faecal dry matter content, blood leucocyte counts and gross, microscopical and electron microscopical features 14-16 days post-inoculation were investigate ... | 2009 | 19640549 |
| phenotypic and genetic diversity among intestinal spirochaetes (genus brachyspira) in free-living wild mallards (anas platyrhynchos) sampled in southern sweden. | brachyspira spp. are anaerobic intestinal spirochaetes that colonize vertebrates. some species cause enteric diseases in pigs, chickens and possibly in humans, whereas others display a commensual relationship with their hosts. the aims were to investigate the prevalence among colonized free-living wild mallards (anas platyrhynchos) of three enteropathogenic brachyspira spp., and to describe the biodiversity of brachyspira spp. isolates. isolates from 150 birds were screened by pcr for 3 pathogen ... | 2011 | 22036527 |
