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...

Oxidized halogen antimicrobials, such as hypochlorous and hypobromous acids, have been used extensively for microbial control in industrial systems. Recent discoveries have shown that acylated homoserine lactone cell-to-cell signaling molecules are important for biofilm formation in Pseudomonas aeruginosa, suggesting that biofouling can be controlled by interfering with bacterial cell-to-cell c...

BACKGROUND Increasing reported cases with Chrombacterium violaceum infection has been noticed in recent decades. It is noteworthy for its difficult-to-treat entity characterized by a high frequency of sepsis, easily distantant metastasis, multidrug-resistance, and frequent relapse, and high mortality rate. METHODS The English-language literature was reviewed from 1952 through December 2009 by...

The pigmentation of the gram-negative bacteria known as Chromobacterium violaceum is characterized by a dark violet color. This study focused on the identification of a gene involved in C. violaceum pigment production. In order to identify one of the genes responsible for pigmentation of this organism, functional genomics methods were implemented using a form of knockout gene; which provides th...
