BACKGROUND Tinea capitis and tinea faciei are dermatophyte infections of the scalp and glabrous skin of the face affecting mainly prepubertal children. During the past 30 years, a significant increase and a change in the pattern of infectious agents has been noted for tinea capitis. OBJECTIVES The aim of this study was to determine trends in the current epidemiological situation of tinea capi...

A gene cluster responsible for the biosynthesis of anticancer agent FK228 has been identified, cloned, and partially characterized in Chromobacterium violaceum no. 968. First, a genome-scanning approach was applied to identify three distinctive C. violaceum no. 968 genomic DNA clones that code for portions of nonribosomal peptide synthetase and polyketide synthase. Next, a gene replacement syst...

Chromobacterium violaceum (C. violaceum) is a facultative anaerobic Gram-negative bacterium in soil or water that rarely causes disease with high mortality. An 8.5-year-old boy developed hypoechoic lesion at the abdominal diameter of 3.5cm x 4.9cm, pneumonia, and dextral pleural effusion. He had been diagnosed suspected tuberculosis granulomatous contact decreased body weight history. fever inc...

Chromobacterium violaceum is a free-living bacterium commonly found in aquatic habitats of tropical and subtropical regions of the world. This bacterium is able to produce a large variety of products of biotechnological and pharmacological use. Although C. violaceum is considered to be non-pathogenic, some cases of severe infections in humans and other animals have been reported. Genomic data o...

Phragmidium violaceum causes leaf rust on the European blackberry (Rubus fruticosus L. aggregate). Multiple strains of this pathogen have been introduced into southern Australia for the biological control of at least 15 taxa of European blackberry, a nonindigenous, invasive plant. In climates conducive to leaf rust, the intensity of disease varies within and among infestations of the geneticall...

Cryptic structure of species complexes confounds an accurate accounting of biological diversity in natural systems. Also, cryptic sibling species often become specialized to different ecological conditions, for instance, with host specialization by cryptic parasite species. The fungus Microbotryum violaceum causes anther smut disease in plants of Caryophyllaceae, and the degree of specializatio...

A Brazilian consortium has unveiled the genomic DNA sequence of the purple-pigmented bacterium Chromobacterium violaceum, a dominant component of the tropical soil microbiota. The sequence provides insight into the abundant potential of this organism for biotechnological and pharmaceutical applications.

Analysis of sequence data from the chloroplast gene ndhF identifies at least 12 major well-supported clades within the genus Solanum. These are briefly described, given informal clade names, and compared with the groups recognized by previous Solanum workers. Non-molecular synapomorphies are proposed for many of the clades. Continued use of informal taxonomic designations is advocated for new i...
