TL;DR
Two cases of plant-related bacterial infections in Argentina were identified using genome sequencing, showing its importance in diagnosing rare pathogens.
Contribution
Demonstrates the effectiveness of whole-genome sequencing in identifying emerging Kosakonia species in clinical settings.
Findings
Whole-genome sequencing identified K. cowanii and K. oryzae as causative agents.
Biochemical and MALDI-TOF MS methods had limitations in identifying the pathogens.
Genomics is crucial for detecting underestimated emerging pathogens.
Abstract
We describe 2 plant-associated posttraumatic Kosakonia infections in Argentina. Facing biochemical and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry limitations, we used whole-genome sequencing to successfully identify K. cowanii and K. oryzae as the causative agents. Our data highlight the crucial role of genomics in correctly identifying these underestimated emerging pathogens.
