AnaerobeHighlights•

Lachnoanaerobaculum gingivalis (L. gingivalis) was newly identified in 2019.

We reported a first case of L. gingivalis bacteremia.

L. gingivalis was confirmed by 16S rRNA gene analysis but not by MALDI-TOF-MS.

L. gingivalis may be overlooked in real setting due to the confused identification.

AbstractCase description

Lachnoanaerobaculum gingivalis is an obligate anaerobe identified in a human dental plaque in 2019. Here, we report the first case of L. gingivalis bacteremia in a patient with oral mucositis during chemotherapy. L. gingivalis was confirmed by 16S rRNA gene analysis but not by MALDI-TOF-MS.

Conclusion

During chemotherapy in patients with oral mucositis, we should consider the possibility of L. gingivalis bacteremia.
