2013). discrimination of “B. hampsonii” and other swine-associated Brachyspira species. Serial passage of a virulent “B. hampsonii” resulted in a laboratory adapted, partially attenuated strain that will be attenuated further and used as a potential vaccine. This serially passaged strain also provides Background “Brachyspira hampsonii”, discovered in North America in 2010 associated with dysentery-like illness, is an economically relevant swine pathogen resulting in decreased feed efficiency and increased morbidity, mortality and medication usage.
2017-08-22 · Initially called Brachyspira sp. Sask30446, the species has now been provisionally named as “Brachyspira hampsonii” [4, 5]. Strains 30,599 and 30,446 are Canadian reference strains of clade I and II, respectively. “ Brachyspira hampsonii ”, discovered in North America in 2010 associated with dysentery-like illness, is an economically relevant swine pathogen resulting in decreased feed efficiency and increased morbidity, mortality and medication usage. Since that time, Brachyspira hampsonii has been detected in Europe, both in pigs and in waterfowl. The origin of B. hampsonii and the timing and reasons for its emergence are unknown. We conducted a retrospective study of historic, archived cases of porcine colitis to determine when B. hampsonii was first evident in

"Brachyspira hampsonii" is a recently described, virulent spirochete capable of inducing clinical swine dysentery in growing pigs. 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.

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.
“Brachyspira hampsonii” is a Gram-negative intestinal spirochete provisionally belonging to the genus Brachyspira. The species shares similar morphology and culture characteristics with other members of the genus. 2014-08-28 · “Brachyspira hampsonii” causes disease indistinguishable from swine dysentery, and the structure of the intestinal microbiome likely plays a role in determining susceptibility of individual pigs to infection and development of clinical disease.

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%). most clinically significant is the recently discovered “Brachyspira hampsonii”(7). Within the Brachyspira genus, all currently iden-tifiedstronglybeta-hemolyticspecies(B.hyodysenteriae,B.suana-tina, and the novel B. hampsonii) are known to cause severe mu-cohemorrhagic diarrhea in pigs, while weakly beta-hemolytic 2013-12-04 · First Identification of “Brachyspira hampsonii” in Wild European Waterfowl Francisco Javier Martínez-Lobo, Álvaro Hidalgo, Marta García, Héctor Argüello, Germán Naharro, Ana Carvajal, Pedro Rubio Name: Brachyspira hampsonii Mirajkar et al. 2017.
