Comparative prevalences of Brachyspira aalborgi and Brachyspira (Serpulina) pilosicoli as etiologic agents of histologically identified intestinal spirochetosis in  


Colonic spirochetosis (CS), defined by histological observation of spirochetal strains of Brachyspira in colonic biopsies, is uncommon and considered of doubtful 

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. Two species of intestinal spirochetes have so far been isolated from humans, namely, Brachyspira (formerly Serpulina) pilosicoli and Brachyspira aalborgi. The majority of the isolates have been referred to as B. pilosicoli ( 9 , 19 , 20 , 29 , 30 ). 2020-12-23 · 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 both rural and urban living individuals.

PDF) Survey on the occurrence of  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. Four flagella are inserted at each end of the cells.

The prevalence of colonization with the anaerobic intestinal spirochaetes Brachyspira aalborgi and Brachyspira pilosicoli was investigated in humans (n= 316) 

Colonic Spirochetal Infections in Nonhuman Primates That Were Associated with Brachyspira aalborgi, Serpulina pilosicoli, and Unclassified Flagellated Bacteria G. E. Duhamel , G. E. Duhamel Currently, the two main genera of clinical interest are Brachyspira and Serpulina, as they include pathogenic as well as commensal species. The genus Brachyspira, originally containing the single species Brachyspira aalborgi, was proposed in 1982(Hovind-Hougen et al., 1982.

Two species, Brachyspira pilosicoli and Brachyspira aalborgi, have been associated with human IS (7). In a study of Dutch patients with gastroenteritis, DNA was 

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). 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

[2] [3] [4] Brachyspira species include pathogens in pigs, birds, dogs, and humans. The colon organisms were Brachyspira aalborgi, documented by antigen test; however, due to lack of material, the spirochetes in the liver could not be typed. As 10 of 13 patients recovered or improved after antibiotic treatment with clarythromycin or metronidazole, our conclusion is that Brachyspira may be pathogenic.

Brachyspira betyder ungefär “kort spiral” är relativt stora bakterier med en öppen/lös spiralform. Brachy kommer av grekiskan ”kort” eftersom de bakterier man isolerade från människan i Danmark (Brachyspira aalborgi) början av 80-talet var relativt korta.

Two species are known to infect humans: B. aalborgi and B. pilosicoli. There is some evidence suggesting that the veterinary pathogenic B. pilosicoli is a potential zoonotic agent, however, since The type species of the genus is Brachyspira aalborgi. There are numerous yet‐to‐be characterized brachyspire species. Brachyspires have fastidious growth requirements requiring chemically complex culture media supplemented with blood or serum. The best studied species, Brachyspira hyodysenteriae, requires cholesterol and phospholipid for Brachyspira aalborgi Hovind-Hougen et al.
