Seventeen Brachyspira aalborgi-like clones derived from colonic mucosa of two healthy adults were almost fully sequenced and subjected to phylogenetic analysis together with 11 Brachyspira reference strains. The analysis divided Brachyspira spp. into two lineages, the B. aalborgi …

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.

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 Aborigin … Brachyspira aalborgi Hovind-Hougen et al., 1983 emend. Ochiai et al., 1997 Species: Brachyspira alvinipulli Stanton et al., 1998 Species: Brachyspira hyodysenteriae (Harris et al., 1972) Ochiai et al., 1998 Species: Brachyspira innocens (Kinyon and Harris, 1979) Ochiai et al., 1998 Species: Brachyspira intermedia (Stanton et al., 1997) Hampson spirochetes Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli. In this study, ﬂuorescent in situ hybrid- ization with oligonucleotide probes targeting 16S or 23S rRNA of B. aalborgi, B 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 whom were also positive for B. aalborgi). For two patients, no product was ampliﬁed. This study demonstrates that B. aalborgi is much more commonly Brachyspira hyodysenteriae was already known as a cause of swine dysentery in veterinary practices.

Brachyspira aalborgi

Its cells are anaerobic, sigmoidal with tapered ends, 2 to 6 µm long. Four flagella are inserted at each end of the cells. The maximal cell width is about 0.2 µm. Brachyspira aalborgi is an extremely slow growing and fastidious spirochete, which previously had been isolated from an HIS patient in Denmark.

Brachyspira species such as Brachyspira aalborgi, Brachyspira pilosicoli, and Brachyspira hominis are known to cause human intestinal spirochetosis.

Three Brachyspira species have been reported to colonize humans: Brachyspira aalborgi, Brachyspira pilosicoli, and the provisionally named “ Brachyspira hominis ” (3 – 7). Although it is unclear whether HIS is associated with clinical symptoms, there is evidence suggesting an association between B. pilosicoli and diarrhea in humans ( 3 , 8 – 11 ).

[1] Brachyspira aalborgi and Brachyspira pilosicoli are members of Brachyspiraceae family. Both have been described in humans and are considered as cause

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.
