Brachyspira hyodysenteriae, a gram-negative anaerobic spirochete, is the primary etiologic agent of swine dysentery and is one of five Brachyspira spp. known to infect swine (Boye et al., 1998). Because disease is less severe when gnotobiotic pigs are experimentally infected, other anaerobic microorganisms normally found in the lower bowel are believed to contribute to lesion development.


2012-12-20 · Brachyspira species are fastidious anaerobic microorganisms, that infect the colon of various animals. The genus contains both important pathogens of livestock as well as commensals. Two species are known to infect humans: B. aalborgi and B. pilosicoli.

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. Name: Brachyspira aalborgi Hovind-Hougen et al. 1983. Category: Species. Proposed as: sp.

The analysis divided Brachyspira spp. into two lineages, the B. aalborgi … The two most commonly involved spirochetes are Brachyspira aalborgi and Brachyspira pilosicoli. Abstracts from the Louisiana American College of Physicians Associates meeting All identified spirochete clones fell into 2 families: the Spirochaetaceae with 2 genera, Cristispira and Spirochaeta, and the Brachyspiraceae, with the genus Brachyspira . Brachyspira aalborgi. Brachyspira aalborgi is a species of bacteria, one of the causative agents of intestinal spirochetosis. Its cells are anaerobic, sigmoidal with tapered ends, 2 to 6 µm long.

In 1982 a small anaerobic spirochete named Brachyspira aalborgi was isolated from a colonic biopsy sample in a histologically identified human case of IS (human intestinal spirochetosis [HIS]) . This spirochete grew even more slowly than the porcine pathogen P43/6/78, taking more than 2 weeks to appear on the plates.

Brachyspira aalborgi

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.

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 Two species of intestinal spirochetes have so far been isolated from humans, namely, Brachyspira(formerly Serpulina) pilosicoliand Brachyspira aalborgi. The majority of the isolates have been referred to as B. pilosicoli(9, 19, 20, 29, 30). The second major grouping within the order Spirochaetales are the Brachyspira, which are intestinal spirochetes classified within the family, Serpulinaceae.

Brachyspira aalborgi

Both spirochete species are known to infect human beings.

Two species of anaerobic intestinal spirochaetes, Brachyspira (formerly Serpulina) pilosicoli and Brachyspira aalborgi , colonise the human large intestine [3, 4]. Both species are associated with a condition known as intestinal spirochaetosis (IS), in which a thin carpet-like layer of spirochaetes is found attached by one cell end to the colorectal surface epithelium [ 5 ].

Orsakande spiroketer rapporteras vara antingen Brachyspira aalborgi eller Brachyspira pilosicoli . De två arterna kan vara zoonotiska eftersom de har isolerats 

För kliniker och patologer kan det vara av värde att känna till detta, eftersom kolonspiroke-tos är behandlingsbart med antibiotika – i första hand med metronidazol. sammanfattat Läs mer Fullständig referenslista och eng-elsk sammanfattning Figur 1.
