BACKGROUND: Chromobacterium violaceum (C. violaceum) is a Gram-negative bacterium capable of causing severe infections in both humans and specific animals. Despite its infrequency, C. violaceum infections exhibit a notably high mortality rate. The timely and precise detection of this pathogen stands as a critical factor in achieving effective diagnosis and treatment. Traditional diagnostic approaches possess limitations, particularly in terms of their time-consuming nature and the range of pathogens they can identify. Metagenomic next-generation sequencing (mNGS) testing has emerged as a highly promising diagnostic tool for infectious diseases.
METHODS: Within this case report, we present a patient who developed a C. violaceum infection subsequent to a lower limb infection, leading to the progression of sepsis, a liver abscess, septic shock, multi-organ dysfunction, and altered mental status. Samples of the patient's blood and tissue from the lower limb skin are collected, and the infection is swiftly diagnosed through mNGS, allowing for the immediate initiation of suitable treatment.
RESULTS: The mNGS results revealed the patient's infection with C. violaceum. Subsequent conventional bacterial culture results were concordant with the mNGS findings. Following comprehensive management measures, including prompt and effective anti-infective treatment, the patient achieved cure and was successfully discharged.
CONCLUSION: This case underscores the significance of employing advanced diagnostic methodologies like mNGS for the early detection of uncommon pathogens such as C. violaceum. The expedited diagnosis and timely intervention hold the potential to substantially enhance patient outcomes in cases of severe infections instigated by this bacterium.
