This study reveals the genomic characteristics of C. haemolyticum, indicating its multidrug-resistance and emphasizing whole-genome sequencing's role in detection.
Chromobacteriumhaemolyticum (C. haemolyticum) is an emerging multidrug-resistant and potentially extensively drug-resistant pathogen capable of causing invasive, lethal infections in humans. Conventional biochemical and mass spectrometry identification methods used in clinical laboratories cannot reliably distinguish it from C. violaceum. This study provides the first report characterizing the genomic features of C. haemolyticum isolated from a young patient in China and reveals the evolutionary patterns of global C. haemolyticum isolates. This research highlights the advantages of whole-genome sequencing for accurate differentiation of Chromobacterium species, raises public awareness about this uncommon pathogen, and provides scientific foundations for improved detection and prevention strategies.
