Chromobacterium violaceum is a free-living microorganism, normally exposed to diverse environmental conditions; it has a versatile energy-generating metabolism. This bacterium is capable of exploiting a wide range of energy resources by using appropriate oxidases and reductases. This allows C. violaceum to live in both aerobic and anaerobic conditions. In aerobic conditions, C. violaceum is abl...

Chromobacterium violaceum is a Gram-negative beta-proteobacterium that inhabits a variety of ecosystems in tropical and subtropical regions, including the water and banks of the Negro River in the Brazilian Amazon. This bacterium has been the subject of extensive study over the last three decades, due to its biotechnological properties, including the characteristic violacein pigment, which has ...

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.

The LuxI/R quorum-sensing system and its associated N-acylated homoserine lactone (AHL) signal is widespread among Gram-negative bacteria. Although inhibition by indole of AHL quorum signalling in Pseudomonas aeruginosa and Acinetobacter oleivorans has been reported previously, it has not been documented among other species. Here, we show that co-culture with wild-type Escherichia coli, but not...

Chromobacterium violaceum, a proteobacterium, is a facultative anaerobe, which is generally present as the normal flora of water and soil in tropical and subtropical regions. The infection due to Chromobacterium violaceum is rare but mostly fatal. It is responsible for causing fatal cases of septicemia, visceral abscesses, skin and soft tissue infections, meningitis, diarrhea, and rarely urinar...

Introduction.Chromobacterium violaceum is an opportunistic human pathogen, associated with significant mortality, and has been reported in patients with chronic granulomatous disease (CGD), a genetic condition causing impaired phagocytosis. Case presentation. A 28-year-old man with a history of CGD presented with fever, pharyngitis, cervical lymphadenopathy and internal jugular vein thrombosis,...

BACKGROUND Tinea capitis is a common dermatophyte infection which constitutes an important public health problem among children worldwide. The endemic nature of scalp ringworm in Africa is perpetuated mainly by the lack of knowledge about the prevalence and carrier status, and the absence of control measures. METHODS Two hundred and nineteen schoolchildren from urban and rural communities of ...

Sir, Dermatophytes are a group of closely-related fungi that are able to invade keratinized tissue (skin, hair and nails) of humans and animals to produce an infection, dermatophytosis, commonly referred to as ringworm or tinea. Important factors leading to the different clinical forms are the infecting fungus, the site infected, the keratinization at that site, and the immune status of the hos...

BACKGROUND AND OBJECTIVES Onychomycosis is a common fungal infection which has been conducted in many parts of the world. The aim of this study was to evaluate the epidemiology and to identify the aetiological factors of onychomycosis in Mazandaran province, Iran. MATERIALS AND METHODS During the period of 10 years (2003-2012) 1100 patients suspected with onychomycosis, referred to the Mycolo...
