Abstract
BACKGROUND
Comamonas kerstersii (C. kerstersii) infections have considered as non-pathogenic to humans, however due to new techniques such as matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS), more cases have been identified.
CASE SUMMARY
This is the first report of a maternal patient with a C. kerstersii bacteremia following caesarean section. Due to the severity of the patient’s condition; high fever and rapidly progressing organ damage, the patient was transferred to the intensive care unit. C. kerstersii was detected by metagenomic next-generation sequencing testing. Based on the drug sensitivity test, appropriate antibiotic treatment was given and the patient recovered fully.
CONCLUSION
This case report confirms that the detection via MALDI-TOF-MS and metagenomic next-generation sequencing testing provides a reliable basis for the diagnosis of this rare bacterial infection.
Core Tip: Comamonas kerstersii (C. kerstersii) infections are rare and have been considered as non-pathogenic to humans. This is the first report of a maternal patient with a C. kerstersii bacteremia following caesarean section. The patient’s condition was critical with high fever and rapidly progressing organ damage and she was treated in the intensive care unit. C. kerstersii was detected by matrix-assisted laser desorption/ionization-time of flight and metagenomic next-generation sequencing testing, which are reliable for the diagnosis of rare bacterial infections.
