The major surface Vsp proteins of Brachyspira hyodysenteriae form antigenic protein complexes.

The Vsp proteins are the major outer membrane proteins of Brachyspira hyodysenteriae, the causative agent of swine dysentery. Eight vsp genes have been identified in B. hyodysenteriae strain B204, arranged into two four-gene loci, and at least two of the corresponding proteins are produced in vitro.

Differential expression of the Bhmp39 major outer membrane proteins of Brachyspira hyodysenteriae.

The enteric, anaerobic spirochete Brachyspira hyodysenteriae is the causative agent of swine dysentery, a severe mucohemorrhagic diarrheal disease of pigs that has economic significance in every major pork-producing country. Recent investigation into potential vaccine candidates has focused on the outer membrane proteins of B. hyodysenteriae.

Characterization of a locus encoding four paralogous outer membrane lipoproteins of Brachyspira hyodysenteriae.

The identification of Brachyspira hyodysenteriae outer membrane proteins (OMPs) that may stimulate immunity to swine dysentery is important for vaccine development. We report here the analysis of a novel locus, blpGFEA, encoding four tandem paralogous proteins of approximately 30 kDa from B. hyodysenteriae.
