| Abstract | In this report, we identified Dialister pneumosintes from blood cultures of two patients with pyometra and lung abscess. Case 1: The 70s-year-old woman, who with cancer of the ascending colon that metastasized to the cervix was undergoing radiation therapy. She complained of fever and abdominal pain, and she was diagnosed with pyometra. Case 2: The 90s-year-old man, who was diagnosed with lung abscess and empyema. D. pneumosintes was detected from his blood cultures and pleural effusion. When D. pneumosintes is detected from blood culture, we should consider possibility that source of infection is abscess including dental oral area. In addition, D. pneumosintes was identified on only 16S rDNA sequencing, previously, but matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) assay could identify D. pneumosintes on these two cases. MALDI-TOF MS identifies D. pneumosintes more easily and may lead to more case reports. |
