Fusospirillosis is a specific infectious disease, characterized by a local ulceration and pseudomembranous exudate, usually on a mucous membrane, and by constitutional symptoms due to toxins produced at the site of the lesion.1 The widespread pathogenesis of the organisms is well known. The usual disorders are the classic Vincent's angina, ulcerative stomatitis and balanitis gangrenosa. The organisms have been found in cases of noma, vulvitis, vaginitis, pelvic peritonitis and hospital gangrene. Pulmonary abscesses, particularly following tonsil-lectomy, have been shown to contain these organisms.
