Brachyspira intermedia strain diversity and relationships to the other indole-positive Brachyspira species.
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...
متن کاملBrachyspira species blood stream infection.
The spirochetes inhabiting the large intestines of humans and animals consist of a diverse group of related organisms. Intestinal spirochetosis caused by Brachyspira pilosicoli is a newly recognized enteric disease of human being and animals manifest as mild colitis and diarrhoea. Few cases have been reported of spirochetaemia especially in critically ill and immunocomprised patients. This is a...
متن کاملBrachyspira species and gastroenteritis in humans.
Brachyspira species have been implicated as a potential cause of gastroenteritis in humans; this is, however, controversial. In 733 gastroenteritis cases and 464 controls, we found 29 samples positive for Brachyspira species (2.3% of cases and 2.6% of controls; P = 0.77). Brachyspira species were not associated with gastroenteritis in humans.
متن کاملIdentification of Brachyspira hyodysenteriae and other pathogenic Brachyspira species in chickens from laying flocks with diarrhea or reduced production or both.
Cecal samples from laying chickens from 25 farms with a history of decreased egg production, diarrhea, and/or increased feed conversion ratios were examined for anaerobic intestinal spirochetes of the genus Brachyspira. Seventy-three samples positive in an immunofluorescence assay for Brachyspira species were further examined using selective anaerobic culture, followed by phenotypic analysis, s...
متن کاملDiagnostic examination of human intestinal spirochetosis by fluorescent in situ hybridization for Brachyspira aalborgi, Brachyspira pilosicoli, and other species of the genus Brachyspira (Serpulina).
Human intestinal spirochetosis, characterized by end-on attachment of densely packed spirochetes to the epithelial surface of the large intestines as a fringe has been associated with the weakly beta-hemolytic spirochetes Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli. In this study, fluorescent in situ hybridization with oligonucleotide probes targeting 16S or 23S rRNA of B. aalbo...
