Phenolic components of ginger (Zingiber officinale), for example gingerol, shogaol and zingerone, have exhibited quorum-sensing inhibitory activity (QSI) against Chromobacterium violaceum
and Pseudomonas aeruginosa, (2) Chemical modification of shogaol to azashogaol and an isoxazoline derivative of gingerol were prepared, both of which exhibited good QSI activity.
Using as biosensor Chromobacterium violaceum
ATCC 31532 and Escherichia coli pSB403, the compounds chlorogenic acid (2), isoorientin (3), orientin (4), isovitexin (6), vitexin (7), and rutin (9) were identified as QS inhibitors.
The API profile from the pus isolate (1156154) initially suggested Chromobacterium violaceum
, a recognized misidentification of B.
is a gram-negative bacteria found in tropical regions.
We describe the case of a 14-year-old boy who was diagnosed with Chromobacterium violaceum
necrotizing fasciitis and subsequently found to have autosornal recessive chronic granulornatous disease.

Moderate growth and utilization was exhibited by Vibrio alginolyticus, Chromobacterium violaceum
The most potent prevented laboratory worms from being killed by a bug called Chromobacterium violaceum
, which often infects people through lacerated skin.
An earlier report on experiments with Chromobacterium violaceum
grown in SM medium containing glucose, sucrose, or 10% LB instead of colloidal chitin as the carbon source indicated that the chitinolytic activity was not induced under these growth conditions (40).
Serratia marcescens, Chromobacterium violaceum
, Micrococcus luteus, and Pseudomonas aeruginosa were plated onto minimal salts motor oil agar to determine the organisms' ability to grow on this media.
1) These pneumonias are associated with many organisms (eg, Aeromonas, Burkholderia pseudomallei, Chromobacterium violaceum
, and Pseudomonas species), and difficult to distinguish from noninfectious adult respiratory distress syndromes.
