avian intestinal spirochaetosis (ais) is a condition arising from colonization of the caeca and colon of birds with anaerobic spirochaetes of the genus brchyspira. the purpose of the present study was to evaluate pcr amplification from formalin-fixed, paraffin-embedded tissue method for detecting infected laying hens with brachyspira pilosicoli with the same primers that have been used for det...
The Brachyspira hyodysenteriae B204 genome sequence revealed three VSH-1 tail genes, hvp31, hvp60, and hvp37, in a 3.6-kb cluster. The location and transcription direction of these genes relative to those of the previously described VSH-1 16.3-kb gene operon indicate that the gene transfer agent VSH-1 has a noncontiguous, divided genome.
No standardized method for susceptibility testing of Brachyspira spp. is currently available. A broth dilution procedure was evaluated and used to test the activities of six antimicrobial agents for 108 isolates of Swedish porcine Brachyspira spp. representing biochemical groups I, II, and III. Group I corresponds to Brachyspira hyodysenteriae, group II corresponds to B. intermedia, and group I...
The aims of this study were to use multilocus sequence typing (MLST) to (i) investigate the population structure, diversity and molecular epidemiology of the weakly haemolytic anaerobic intestinal spirochaete Brachyspira intermedia, and (ii) determine the relationship of the species to the other two indole-positive but strongly haemolytic Brachyspira species--B. hyodysenteriae and "B. suanatina...
Specimens of colonic mucosa from two pigs with diarrhea were examined by light and electron microscopy. The epithelial surfaces of both pigs were extensively colonized by large spirochetes morphologically compatible with Treponema hyodysenteriae or Treponema innocens. The microorganisms were intimately attached end-on to the luminal cells. A weakly beta-hemolytic spirochete similar to T. innoce...
BACKGROUND The clinical significance of intestinal spirochetosis is uncertain, therefore the aim of the present paper was to assess the prevalence of histological intestinal spirochetosis in patients with and without chronic watery diarrhea and to evaluate its clinical relevance. METHODS A prospective diagnostic work-up of intestinal spirochetosis was made on biopsy samples taken from patient...
