Dichelobacter nodosus, formerly Bacteroides nodosus, is a Gram-negative, obligate anaerobe of the family Cardiobacteriaceae. It has polar fimbriae and is the causative agent of ovine foot rot as well as interdigital dermatitis.[1] It is the lone species in the genus Dichelobacter.

Dichelobacter nodosus, formerly Bacteroides nodosus, is a gram negative, rod shaped, obligate anaerobe of the family Cardiobacteriaceae. It has polar fimbriae epitomes that separate the bacteria into multiple serogroups.[2]

D. nodosus, along with Fusobacterium necrophorum, co-exist as the causative agents of ovine foot rot and interdigital dermatitis in ungulates globally, especially in temperate zones.[3][4][5] Clinical signs can vary into two categories; virulent and benign, with the distinction between the two varying dependent on location.[6][7]

Treatment options include footbaths, parenteral administration of long-acting antimicrobials, concurrent use of vaccines, and removal of affected sheep into a clean, quarantined area.[6][3][8][9][10] Environmental management and treatment of infected is required to prevent further bacterial spread.[6]
