Chromobacterium violaceum infection is rare but causes a high mortality rate particularly in immunosuppressed persons. Since its clinical presentation is non-specific and the diagnosis basically relies upon blood culture and sensitivity, this infection should be considered among the organisms targeted empirically for antibiotic therapy when a cellulitis or rapidly progressive illness follows ex...

Chromobacterium violaceum, a saprophyte bacterium found commonly in soil and water in tropical and subtropical climates, is a rare cause of severe, often fatal, human disease. We report 1 confirmed and 2 suspected cases of C. violaceum septicemia, with 2 fatalities, in siblings after recreational exposure in northeastern Brazil.

The draft genome sequences of two Chromobacterium violaceum strains isolated from the Rio Negro are reported here. These bacteria carry most genetic systems associated with the production of bioactive compounds, but unlike other C. violaceum strains, they lack a dedicated operon for arsenic resistance.

This is the first report of Chromobacterium violaceum strains that are aerogenic. Two pigmented strains of C. violaceum and their nonpigmented variants produced gas in glucose broth. Kliger iron agar, and triple sugar iron agar. They were similar morphologically and biochemically to other anaerogenic strains studied previously.

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...

Chromobacterium violaceum infection is confined to the tropical and subtropical areas, with almost all reported cases occurring in the Southeast. The most common feature of this infection is sepsis, followed by cutaneous involvement and liver abscesses. Treatment consists of surgical drainage of purulent collections and appropriate antimicrobial therapy, such as chloramphenicol, gentamicin, imi...

Chromobacterium violaceum is a Gram-negative bacterium found in a wide variety of tropical and subtropical ecosystems. The complete genome sequence of C. violaceum ATCC 12472 is now available, and it has considerable biotechnological potential for various applications, such as environmental detoxification, as well as medical and agricultural use. We examined the biotechnological potential of C....

Tinea capitis is of public health importance because of its transmissibility. Trichophyton violaceum and Trichophyton soudanense, which are common causes of tinea capitis in parts of Africa and West Asia, have only rarely been reported to cause dermatophytoses in the United States. We identified 24 patients with 25 positive cultures for T. violaceum or T. soudanense that were processed in a sin...

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,...

Chromobacterium violaceum is a gram negative, facultative anaerobic coccobacillus. Human infections are rare and usually occur after exposure to contaminated soil or water. Infections can present with fulminant septicemia, multiple abscesses and rapidly spreading soft tissue infections. Here we present a fatal case of pulmonary Chromobacterium violaceum infection following aspiration of drain w...
