Septic shock caused by Slackia exigua in a patient with diabetes.

We report a case of septic shock caused by Slackia exigua, an obligatory anaerobic gram-positive rod, in an 82-year-old woman with diabetes. Dental assessment revealed a palatal lesion and untreated periodontitis. Although a resident species in the oral cavity and associated with localized disorders, S. exigua can cause extra-oral diseases, which can be fatal in individuals with risk factors, such as diabetes. Thus, control of oral lesions caused by S. exigua is important to prevent systemic infection.
