Recently, dysentery-like disease has been reported in association with infection by strongly beta-hemolytic spirochetes which are not identified as B. hyodysenteriae. Detection of subclinical Brachyspira hyodysenteriae infection in pig herds using feces is challenging. However, the ability to detect the pathogen in intestinal samples of slaughtered pigs has not been investigated, to our knowledge. Therefore, we determined the detection of B. hyodysenteriae in the 2020-09-17 · There are four other Brachyspira species in pigs: Brachyspira innocens which is considered non-pathogenic.

Swine dysentery (SD) is a mucohaemorrhagic colitis of pigs resulting from infection of the large intestine with the anaerobic spirochaete Brachyspira hyodysenteriae [1]. The disease has a worldwide distribution and causes significant economic loss. Successful control programs for SD rely on accurate, cost-effective and timely detection of infected herds and animals. Two species of Brachyspira are well-recognized pathogens of pigs: B pilosicoli and B. hyodysenteriae.
