The genome of Chromobacterium subtsugae strain PRAA4-1, a betaproteobacterium producing insecticidal compounds, was sequenced and compared with the genome of C. violaceum ATCC 12472. The genome of C. subtsugae displayed a reduction in genes devoted to capsular and extracellular polysaccharide, possessed no genes encoding nitrate reductases, and exhibited many more phage-related sequences than w...

Chromobacterium violaceum causes a rare infection in human, usually in tropical or subtropical areas. We report a fatal case of C. violaceum infection affecting a 40-year-old previously healthy man in Hong Kong. He presented with a wound infection and lymphadenitis. Despite multiple antibiotic treatment, including ciprofloxacin, he succumbed shortly after admission to the hospital. We report th...

Because of increasing antimicrobial resistance, the treatment of the asymptomatic bacteriuria is not considered except in specific circumstances like during pregnancy or before invasive urologic procedures. We are reporting a first case of asymptomatic bacteriuria caused by Chromobacterium violaceum in a 16-year-old male. With the reporting of the C. violaceum which is notorious for its high pr...

Chromobacterium violaceum is found in tropical and subtropical regions; it is the only Chromobacterium species pathogenic for humans. Due to its rare presentation, physicians often ignore the importance of this pathogen. We report a fulminant fatal case of bacteremia in a 38-year-old Colombian man. The clinical manifestations were fever, thoracic pain, respiratory failure and death. His conditi...

In this study, the antifungal activities of limonene against Trichophyton rubrum were evaluated via broth microdilution and vapor contact assays. In both assays, limonene was shown to exert a potent antifungal effect against T. rubrum. The volatile vapor of limonene at concentrations above 1 µl/800 ml air space strongly inhibited the growth of T. rubrum. The MIC value was 0.5% v/v in the broth ...

Chromobacterium violaceum is a gram negative oxidase positive bacillus that causes human infections infrequently. It is a normal inhabitant of soil and stagnant water of the tropical and subtropical areas. In humans, it can cause infections ranging from life threatening sepsis with metastatic abscesses to skin infections and urinary tract infections. The organism is notoriously resistant to mos...

Fungicidal activities of pentachloronitrobenzene and derivatives were tested with Candida albicans, Aspergillus fumigatus, Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporon canis. In relation to pentachloronitrobenzene, no increasing fungistatic activities were found with cysteine derivatives. Rising fungistatic activities were seen with pentachlorophenylmethylsulfone and, in so...
