Serologic detection of Brachyspira (Serpulina) hyodysenteriae infections.
Swine dysentery (SD) caused by the intestinal spirochete Brachyspira hyodysenteriae is an economically important disease in pig-producing countries throughout the world. To date, no specific serologic assay is commercially available for the diagnosis of pigs with SD. Several serologic techniques have been identified in the past; however, these tests have all used either whole-cell proteins or l...
متن کاملComplete genome sequence of Brachyspira murdochii type strain (56-150T)
Brachyspira murdochii Stanton et al. 1992 is a non-pathogenic, host-associated spirochete of the family Brachyspiraceae. Initially isolated from the intestinal content of a healthy swine, the 'group B spirochaetes' were first described as Serpulina murdochii. Members of the family Brachyspiraceae are of great phylogenetic interest because of the extremely isolated location of this family within...
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...
متن کاملComparative prevalences of Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli as etiologic agents of histologically identified intestinal spirochetosis in Australia.
DNA from gastrointestinal biopsy specimens from 28 Australian patients with histologic evidence of intestinal spirochetosis (IS) was subjected to PCRs to amplify segments of the 16S rRNA and NADH oxidase genes of Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli. B. aalborgi was identified in specimens from 24 (85.7%) patients and B. pilosicoli in those from 4 (14.3%) patients (2 of w...
متن کاملBrachyspira intermedia and Brachyspira pilosicoli are commonly found in older laying flocks in Pennsylvania.
Anaerobic intestinal spirochetes (genus Brachyspira) include several species that are recognized as pathogens of poultry. Surveys undertaken in Europe and Australia have shown that layer and breeder flocks are often colonized by the pathogenic species Brachyspira intermedia and Brachyspira pilosicoli, but similar surveys have not been conducted in the United States. In the current study, DNA wa...
