Heh E, Allen JC, Raynor M, Hock RA, Peralta DP. Capnocytophaga sputigena Tonsillitis in a Patient With Acute Myeloid Leukemia. Cureus 2024; 16:e56551. [PMID: 38646309 PMCID: PMC11027020 DOI: 10.7759/cureus.56551] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Accepted: 03/20/2024] [Indexed: 04/23/2024] Open
Abstract
Capnocytophaga sputigena is a gram-negative facultatively anaerobic, capnophilic bacterium typically residing in the human oropharyngeal flora. This opportunistic pathogen can cause a wide range of infections, from bacteremia to septic abortion. However, it is exceedingly rare for a patient to present with tonsillitis due to C. sputigena. Herein, we discuss the presentation, hospital course, and clinical trajectory of a patient experiencing complications of tonsillitis related to C. sputigena in the context of acute myeloid leukemia. Additionally, we delve into the treatment approaches and challenges in managing this particular pathogen.

Capnocytophaga sputigena bloodstream infection in hematopoietic stem cell transplantations: two cases report and review of the literature. Rev Inst Med Trop Sao Paulo 2020; 62:e48. [PMID: 32667390 PMCID: PMC7359719 DOI: 10.1590/s1678-9946202062048] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Accepted: 06/24/2020] [Indexed: 12/03/2022] Open
Abstract
Capnocytophaga is a group of facultative anaerobic gram-negative bacteria present in the oral cavity of humans, dogs and cats, as part of their normal oral flora. Here, we described two cases of bloodstream infections (BSI) caused by Capnocytophaga in neutropenic autologous hematopoietic stem cell transplantation (auto-HSCT) patients with mucositis (Grade I and Grade III) identified by Maldi-Tof. They were successfully treated with β-lactam (meropenem and piperacillin-tazobactam). The species C. sputigena was confirmed by 16S rRNA gene sequencing in one patient. The review of literature showed that C. ochraceae was the most frequent species causing BSI in auto-HSCT patients and that the patients usually presented mucositis and were neutropenic at the onset of the infection.

[PMID: 31275806 PMCID: PMC6587014 DOI: 10.1016/j.idcr.2019.e00572] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 06/07/2019] [Accepted: 06/08/2019] [Indexed: 11/29/2022] Open
Abstract
Capnocytphaga sputigena is a commensal of the subgingival throat. Capnocytophaga sputigena is a rare cause of pneumonia. The boarder from commensal bacteria to pathogen bacteria is narrow.
Capnocytophaga sputigena is an unusual cause of community-acquired pneumonia. A 22-year-old woman presented an amoxicillin-resistant pneumonia. Sputum examination detected C. sputigena from 3 specimens with a significant bacterial load. The strain produced beta lactamase. Evolution was favorable after introduction of amoxicillin-clavulanate acid. Physicians might be aware of the presence of this unusual bacterium in cases of community-acquired pneumonia.
