Abstract
Campylobacter rectus, formerly known as Wolinella recta, is an anaerobic Gram-negative bacillus, generally recognized as an agent responsible for severe periodontitis; only two cases of extra-oral infections have been reported. The first case of septicemia with C rectus and Actinomyces odontolyticus is described in a 37-year-old farmer who suffered from severe sacroiliitis. Also presented are a review of C rectus in human pathology, and a brief review of pyogenic sacroiliitis, a rather rare disease.
