This study demonstrates that B. aalborgi is much more commonly Brachyspira aalborgi Hovind-Hougen et al., 1983 emend.

Faecal samples included 287 from rural patients with gastrointestinal symptoms, comprising 142 from non-Aboriginal and 145 from Aborigin … Seventeen clones from two individuals and 11 reference strains were analyzed and the intestinal spirochetes could be divided into two lineages, the Brachyspira aalborgi and the Brachyspira hyodysenteriae lineages. All of the clones grouped in the B. aalborgi lineage. Brachyspira aalborgi is an extremely slow growing and fastidious spirochete, which previously had been isolated from an HIS patient in Denmark. Recent studies using polymerase chain reaction amplification of DNA from intestinal biopsies from a series of cases of HIS in the general Western population demonstrated that B. aalborgi, anaerobic intestinal spirochaete Brachyspira aalborgi, to modify this for use as a selective isolation medium and then to test the medium for its effectiveness in isolating B. aalborgi from patients’ faeces. Of the media evaluated, brain heart infusion agar (BHIA) with 10% bovine blood (BB) was Brachyspira aalborgi infection in four Australian children Brachyspira aalborgi infection in four Australian children Heine, Ralf G; Ward, Peter B; Mikosza, Andrew Sj; Bennett‐Wood, Vicki; Robins‐Browne, Roy M; Hampson, David J 2001-08-01 00:00:00 Aim: The clinical presentation of four children and adolescents (two males and two females with a mean age of 12.4 years; range 9–16 years Brachyspira hyodysenteriae was already known as a cause of swine dysentery in veterinary practices.

Brachyspira aalborgi

Orsakar bakterien Brachyspira IBS?

Brachyspira species include pathogens in pigs, birds, dogs, and humans. Three Brachyspira species have been reported to colonize humans: Brachyspira aalborgi, Brachyspira pilosicoli, and the provisionally named “ Brachyspira hominis ” (3 – 7). In 1982 a small anaerobic spirochete named Brachyspira aalborgiwas isolated from a colonic biopsy sample in a histologically identified human case of IS (human intestinal spirochetosis [HIS]) (3).

Brachyspira aalborgi

aalborgi, of Aalborg, named for the Danish town Aalborg in which the rectal biopsies containing the spirochete were taken from human diarrheic patients Brachyspira ibaraki ♠ (presumably an 16S-rDNA variant of B. aalborgi) ♠ Tachibana et al. 2003 Brachyspira innocens (Kinyon and Harris 1979) Ochiai et al. 1998 Brachyspira intermedia (Stanton et al. 1997) Hampson and La 2006 The two other Brachyspira species, B. aalborgi and B. hominis appear to be primate adapted, being found in humans and subhuman primates5 where they mostly cause no inflammatory response. An Australian survey found that B. pilosicoli infection is largely confined to rural aboriginals (15%), with B. aalborgi being less prevalent (5%) but found in In contrast, B. aalborgi occurs more frequently in developed countries, typically in AIDS patients with chronic diarrhea. The pathogenic potential of Brachyspira for humans is controversial.

The genus Brachyspira, originally containing the single species Brachyspira aalborgi, was proposed in 1982(Hovind-Hougen et al., 1982. B. aalborgi colonizes humans and its pathogenicity remains uncertain. aalborgi and Brachyspira pilosicoli in the feces of captive nonhuman primates (n 35) from 19 species housed at the Zoological Gardens, Perth, Western Australia.

This study reports for the first time the detection of Brachyspira aalborgi in faeces and rectal biopsies of a female suffering for 3-4 months of abdominal pain with long-standing mucosal diarrhoea, rectal bleeding and suspected carcinoma of the rectum.
