After i.v. inoculation with Rhodococcus aurantiacus, wild-type (WT) mice develop nonnecrotic, epithelioid granulomas. Because a high level of TNF-alpha is observed during the initial phase postinfection, we examined the extent to which TNF-alpha contributes to granulomatous inflammation using TNF-alpha gene-deficient (TNF-alpha(-/-)) mice. Despite a lack of R. aurantiacus proliferation, TNF-alp...

A case of severe progressive subcutaneous abscesses and necrotizing tenosynovitis of the right arm of a 30-year-old woman caused by Rhodococcus aurantiacus is reported.

Chloroflexus aurantiacus J-10-f1 is an anoxygenic, photosynthetic, facultative autotrophic gram negative bacterium found from hot spring at a temperature range of 50-60°C. It can sustain itself in dark only if oxygen is available thereby exhibiting a dark orange color, however display a dark green color when grown in sunlight. Genome of the organism contains total of 3853 proteins out ...

The anamorphic basidiomycete genus Marchandiomyces presently includes two common lichenicolous (lichen-inhabiting) species, M. corallinus and M. aurantiacus (teleomorph Marchandiobasidium aurantiacum). We describe here a new species, M. lignicola sp. nov., that is similar to M. corallinus in the colour of its sclerotia, but differs in having a wood-inhabiting (lignicolous) habit. The phylogenet...

Chloroflexus aurantiacus is a facultative autotrophic green nonsulfur bacterium that grows phototrophically in thermal springs and forms microbial mats with cyanobacteria. Cyanobacteria produce glycolate during the day (photorespiration) and excrete fermentation products at night. C. aurantiacus uses the 3-hydroxypropionate bi-cycle for autotrophic carbon fixation. This pathway was thought to b...

Leafhopper species Macropsidius duuschulus Dlabola and M. niger Matsumura are recorded for the first time from China. Macropsidius fukangensis (Li et Xu) comb. nov. (from Macropsis) is proposed. A new species, Pediopsis bannaensis sp. nov., is described and illustrated from China and Thailand.

Superoxide dismutase from the thermophilic anoxygenic photosynthetic bacterium Chloroflexus aurantiacus was cloned, purified, and characterized. This protein is in the manganese- and iron-containing family of superoxide dismutases and is able to use both manganese and iron catalytically. This appears to be the only soluble superoxide dismutase in C. aurantiacus. Iron and manganese cofactors wer...

We report that Gordona aurantiaca (Rhodococcus aurantiacus) caused a lung infection in humans. The case of a 50-year-old male farmer is shown. This is the first report of infection by this organism.

Gene annotation plays a key role in subsequent biochemical and molecular biological studies of various organisms. There are some errors in the original annotation of sequenced genomes because of the lack of sufficient data, and these errors may propagate into other genomes. Therefore, genome annotation must be checked from time to time to evaluate newly accumulated data. In this study, we evalu...
