The incidence of swine dysentery has increased in recent years and "B. hampsonii" has been recovered from pigs with clinical dysentery throughout the major pig-rearing areas of the United States as well as Canada. Since that time, Brachyspira hampsonii has been detected in Europe, both in pigs and in waterfowl.

The incidence of swine dysentery has increased in recent years and "B. hampsonii" has been recovered from pigs with clinical dysentery throughout the major pig-rearing areas of the United States as well as Canada. 70 Brachyspira spp. that these isolates likely represent a novel species, for which the name “Brachyspira hampsonii” has been proposed (Chander71 and others 2012). The current case 72 report describes, to the best of our knowledge, the first confirmed “B. hampsonii” infection in 73 pigs outside North-America.

Discussion “Brachyspira hampsonii” was described in North American pigs with swine dysentery-like symptoms.Since molecular diagnostic methods had been focused on the detection of the known pathogens, B. hyodysenteriae and B. pilosicoli, these cases of diarrhea in pigs had been unresolved until the other isolates, which were so far summarized as “non-typeable Brachyspira species With the emergence of "Brachyspira hampsonii" associated with swine dysentery in North America, identification of effective treatments and interventions is a pressing need.

Brachyspira hampsonii

2017-01-31 · We compared the detection frequency of “Brachyspira hampsonii” PCR performed on rectal GenoTube swabs, to PCR performed directly on a sample of feces, to anaerobic culture of a standard rectal swab on Brachyspira-specific agar (gold standard).

2017-01-31 With the emergence of "Brachyspira hampsonii" associated with swine dysentery in North America, identification of effective treatments and interventions is a pressing need. Denagard® (tiamulin hydrogen fumarate) Liquid Concentrate 12.5% is approved in the United States for treatment of dysentery caused by Brachyspira hyodysenteriae at 0.006% in the water. Explants exposed to "B. hampsonii" for 12 hours had a greater number of necrotic cells and thicker catarrhal exudate than control explants. Interaction of spirochaetes with the epithelium, necrotic cells and crypts was visible under optical microscopy, and a trend of increased expression of IFN-γ and e-cadherin in inoculated explants relative to control explants was observed. Swine dysentery is classically associated with infection by the strongly beta-hemolytic Brachyspira hyodysenteriae; however, the proposed novel species "Brachyspira hampsonii" has also been isolated from clinical cases of dysentery in the United States and Canada.

hampsonii” clade I or clade II based on nox gene sequences are proposed as “B. hampsonii” in this paper. hampsonii" and separated from other Brachyspira spp. isolates and reference strains. Additionally, this cluster was related to clades that grouped B. murdochii and B. innocens isolates.

hyodysenteriae, B. suanatina, and the novel B. hampsonii) are known to cause severe mucohemorrhagic diarrhea in pigs, while weakly beta-hemolytic Brachyspira species are either commensals (B. innocens) or are capable of causing diarrhea and/or colitis (B. pilosicoli, B. murdochii, B. intermedia, B. aalborgi, and B. alvinipulli) in pigs, chickens and/or humans . Brachyspira spp. were isolated from 51 of the 205 faecal samples collected from graylag geese and mallards in the Villafáfila Lagoons Nature Reserve (Northwestern Spain). The Brachyspira species identified through phenotyping, PCR and sequencing of the nox gene were B. pilosicoli (5.9%), B. alvinipulli (11.8%), "B. hampsonii" (19.6%), B. murdochii (23.5%) and B. innocens (39.2%).

However, other Brachyspira species have been increasingly associated with intestinal disorders in pigs. This case report describes the first diagnosis of a “Brachyspira hampsonii” infection in Brachyspira is a genus of bacteria classified within the phylum Spirochaetes. Brachyspira species include pathogens in pigs, birds, dogs, and humans. Brachyspira strains previously identified in USA and Canada as B. hampsonii, what supports the identification of isolates obtained in Spain as B. hampsonii .
