Chromobacterium pseudoviolaceum LMG 3953T was separated from Chromobacterium violaceum in 2009, but little is known of its origin or environmental role. Here, the genome of LMG 3953T was sequenced to understand the evolution of the genus Chromobacterium It is not clear from this sequence that C. pseudoviolaceum is taxonomically distinct from C. violaceum.

Strain PRAA4-1(T), a motile, Gram-negative, violet-pigmented bacterium, was isolated from Maryland forest soil and found to be orally toxic to Colorado potato beetle larvae and other insects. Morphological, biological, biochemical and molecular characterization revealed that this strain was most similar to Chromobacterium violaceum, the type species and only currently recognized member of the g...

Lymphadenitis can be caused by different gram positive and gram negative bacteria and non-tuberculous mycobacteria. Cervical lymphadenitis in children is thought to result from ingestion of or contact with environmental microrganisms. Chromobacterium violaceum is a common inhabitant of soil and water in tropical and sub tropical countries. In these parts of the world Chromobacterium violaceum i...

Chromobacterium violaceum is a proteobacterium found in soil and water in tropical regions which rarely causes infection in humans. Here, we report a fatal bacteremia caused by Chromobacterium violaceum in Vietnam. We describe a number of clinical, microbiological, and molecular aspects associated with this bacterial infection.

A strain of Chromobacterium violaceum has been isolated which produces bacteriophage tail-like particles in high numbers. The extracellular morphology and the intracellular arrangement of these particles are described.

Chromobacterium violaceum is an abundant component of the soil and water microbiota in tropical and subtropical regions around the world. For many years, it was mainly known as a producer of violacein and as a reporter for the discovery of quorum sensing molecules. However, C. violaceum has recently emerged as an important model of an environmental opportunistic pathogen. Its high virulence in ...

Iodobacter species are among a number of freshwater Gram-negative violacein-producing bacteria. Janthinobacterium lividum and Chromobacterium violaceum have had their whole genomes sequenced and annotated. This is the first report of a draft whole-genome sequence of a violacein-producing Iodobacter strain that was isolated from the Hudson Valley watershed.

A 69-year-old woman was admitted to our hospital with the chief complaints of fever and fatigue. We initially treated the patient for a tick-borne disease after noticing a pustule on her leg; however, abdominal computed tomography (CT) showed multiple low-density areas in the liver and Chromobacterium violaceum was isolated from a blood culture. We diagnosed her with multiple liver abscesses se...

Strain CC-SEYA-1T, a motile, Gram-negative, non-violet-pigmented bacterium, was isolated on nutrient agar from spring-water samples collected from Yang-Ming Mountain, Taipei County, Taiwan. 16S rRNA gene sequence studies showed that the strain clustered with Chromobacterium violaceum (96.8 % similarity) and Chromobacterium subtsugae (96.5 % similarity), followed by Aquitalea magnusonii (95.8 % ...

Chromobacterium violaceum, a soil and water inhabitant, has been implicated in human disease with a high mortality rate, particularly in the southeastern United States. The psychrotrophic Chromobacterium lividum has been isolated from foods, water, and soil, but is not considered pathogenic. To determine the distribution of Chromobacterium spp. in soil, water, and foods in the Gainesville area,...
