A comparison of the morphologic effects of Serpulina hyodysenteriae or its beta-hemolysin on the murine cecal mucosa. (lookformedical.com)
Studies were carried out to compare the early morphologic changes in the cecal mucosa of mice either infected with Serpulina hyodysenteriae or exposed to the beta-hemolysin of S. hyodysenteriae. (lookformedical.com)
Brachyspira ( B. ) hyodysenteriae is widespread globally, and can cause mucohaemorrhagic colitis (swinedysentery, SD) with severe economic impact in infected herds. (biomedcentral.com)
Three species of anaerobic intestinal spirochaetes have been shown to be capable of causing SD, of which Brachyspira hyodysenteriae is the most common and widespread [ 1 ]. (biomedcentral.com)
For example, Witters and Duhamel demonstrated that B. hyodysenteriae strain B78 T , which is less virulent than strains B204 and B234, had higher haemolysin titres than the latter two strains [ 7 ]. (biomedcentral.com)
Species4
B. pilosicoli is unique from other Brachyspira species because it colonizes a variety of domestic animals including pigs, chickens, dogs, wild birds, rodents, and humans. (wikipedia.org)
It wasn't until the mid-1990s that the pathogen was attributed to all three host species under the species name Brachyspira pilosicoli. (wikipedia.org)
Despite being isolated in other species, Brachyspira pilosicoli remains predominantly a spirochete associated with porcine intestinal spirochetosis. (wikipedia.org)
Because of this, to accurately determine species-level identification of Brachyspira species, genetic sequencing should be considered (i.e. (wikipedia.org)
Anaerobic2
Brachyspira pilosicoli is a gram-negative, anaerobic, host-associated spirochete that colonizes the intestinal tract of animals and humans. (wikipedia.org)
Brachyspira pilosicoli is a gram-negative, anaerobic, spirochete bacteria that is approximately 4 - 10 um in length and 0.2 - 0.3 um in width. (wikipedia.org)
Remains1
consequently, some uncertainty remains about the precise identity of the haemolysin(s). (biomedcentral.com)
Agent1
Although spirochetes have been described dating back to 1877, it would be another hundred years before Brachyspira pilosicoli would be first described in 1980, and recognized as a causative agent of diarrhea and dysentery in pigs. (wikipedia.org)
Variety1
Following these early descriptions, Brachyspira pilosicoli was discovered in various human populations including Asian communities, homosexual communities, and a wide variety of communities within Muscat, the capital of Oman. (wikipedia.org)
