A case of bacteremia caused by Dialister pneumosintes and Slackia exigua in a patient with periapical abscess

摘要

Dialister pneumosintes and Slackia exigua are both obligatory anaerobe and known to be associated with periodontal diseases and other oral infection. We report a case of blood stream infection caused by D. pneumosintes and S. exigua. This occurred in a 78-year-old female patient that presented with general weakness and fever. We revealed that she had a periapical absecess. The blood culture was positive for D. pneumosintes and S. exigua; however, identifying them was challenging. Ultimately,165 rRNA sequencing was used to identify the organisms. The patient recovered after being treated with ceftriaxone and clindamycin. To the best of our knowledge, this is the first report of bacteremia caused by mixed infection of D. pneumosintes and S. exigua. (C) 2015 Elsevier Ltd. All rights reserved.
