Abstract:
We report the first identification in Ecuador of the microorganism Comamonas kerstersii, a strain isolates from a sample of fluid from the abdominal cavity and identified by the technique of mass spectrometry MALDITOF. It was obtained during the surgical act of a patient with the diagnosis of acute peritonitis, secondary to a perforated appendicitis. This microorganism is considered a rare pathogen. Even though the genus to which it belongs has a wide geographical distribution, this pathogen is considered an opportunistic agent.
Insights
This study reports the first identification of Comamonas kerstersii in Ecuador, a rare opportunistic pathogen found in a patient with peritonitis. The microorganism was isolated from abdominal fluid and identified using MALDI-TOF mass spectrometry.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Diagnostics
Background:
- Comamonas kerstersii is a rare opportunistic pathogen.
- The genus Comamonas has a wide geographical distribution.
- Abdominal infections can be caused by various microorganisms.
Purpose of the Study:
- To report the first identification of Comamonas kerstersii in Ecuador.
- To describe the isolation and identification of this rare pathogen from a clinical sample.
Main Methods:
- Sample collection from the abdominal cavity during surgery.
- Identification of the microorganism using Matrix-Assisted Laser Desorption/Ionization-Time Of Flight (MALDI-TOF) mass spectrometry.
Main Results:
- Comamonas kerstersii was successfully identified in a patient with acute peritonitis secondary to perforated appendicitis.
- The isolate was obtained from abdominal fluid.
Conclusions:
- This finding represents the first documented case of Comamonas kerstersii in Ecuador.
- The identification highlights the potential role of this rare pathogen in intra-abdominal infections.
