This study examined the prevalence of the intestinal spirochaetes Brachyspira aalborgi and Brachyspira pilosicoli in different Western Australian (WA) populations. Faecal samples included 287 from rural patients with gastrointestinal symptoms, comprising 142 from non-Aboriginal and 145 from Aboriginal people; 227 from recent healthy migrants to WA from developing countries; and 90 from healthy ...
When cultures of Brachyspira hyodysenteriae were grown under a wide range of in vitro conditions, at least 1% of the cells formed spherical bodies different to the normal helical form. This percentage increased considerably in aging cultures or following their incubation in caramelized media. Spherical body formation was initiated from a terminal localized swelling of the outer sheath followed ...
Brachyspira hyodysenteriae is an anaerobic intestinal spirochete that colonizes the large intestine of pigs and causes swine dysentery, a disease of significant economic importance. The genome sequence of B. hyodysenteriae strain WA1 was determined, making it the first representative of the genus Brachyspira to be sequenced, and the seventeenth spirochete genome to be reported. The genome consi...
A new species of the Bryophila (Scythobrya) salomonis species-group, B. kaszabi sp. n. is described. A diagnostic comparison is made with B. miltophaea Hampson, 1908 and B. plumbeola Staudinger, 1881. Adults, male and female genitalia of the new and related species are illustrated.
Previously-developed PCR protocols specific for the 16S rRNA gene of the intestinal spirochaetes Brachyspira aalborgi and Brachyspira pilosicoli were adapted for the detection of these species in human faeces, following DNA extraction and purification using mini-prep columns. The limits of detection in seeded faeces for B. aalborgi and B. pilosicoli respectively were 2x10(2) and 7x10(3) cells p...
Spirochaetosis is an infection caused by Brachyspira which are Gram-negative bacteria. The disease classically affects the large bowel and appendix has not been previously described in gallbladder. diagnosed on histology a characteristic microscopic appearance. We report case of spirochaetosis gallbladder, found incidentally cholecystectomy specimen, 65-year-old male with acute-on-chronic chole...
Objective: A serological screening study was carried out to determine the prevalence of Lawsonia (L.) intracellularis infections in German pig herds. Additionally a cross-sectional study of eight farrow-to-finish herds which was designed to investigate the dynamics of seroconversion. In addition, bacteriological tests were carried out on faec-al and intestinal samples from herds with diarrhoea ...
