The isolation of fusobacteria from tropical ulcers

Tropical ulcer is a disease found most commonly in the tropics, although the disease is not confined to those areas. Young children are affected most frequently and the disease is thought to be a polymicrobial infection with fusobacteria, aerobic microorganisms and spirochaetes each playing a role. The fusobacteria have been reported on smears but have not been cultured thus far. We report the isolation and culture of these organisms from 46 ulcers and have also demonstrated the same organisms in skin biopsies from these lesions.
