Rhodococcus is an emerging cause of opportunistic infection in immunocompromised patients, most commonly causing cavitary pneumonia. It has rarely been reported as a cause of isolated bacteremia. However, the relationship between bacteremia and central venous catheter is unknown. Between 2002 and 2010, the characteristics and outcomes of seventeen cancer patients with Rhodococcus bacteremia and...

The current systematics of the genus Rhodococcus is unclear, partly because many members were originally included before the application of a polyphasic taxonomic approach, central to which is the acquisition of 16S rRNA sequence data. This has resulted in the reclassification and description of many new species. Hence, the literature is replete with new species names that have not been brought...

Growth and cesium accumulation characteristics of two cesium-accumulating bacteria isolated from soils were investigated. Rhodococcus erythropolis CS98 and Rhodococcus sp. strain CS402 accumulated high levels of cesium (approximately 690 and 380 mumol/g [dry weight] of cells or 92 and 52 mg/g [dry weight] of cells, respectively) after 24 h of incubation in the presence of 0.5 mM cesium. The opt...

The taxonomic position of an actinomycete, strain K07-23T, isolated from a cold desert of the Himalayas, India, was established by a polyphasic approach. The strain exhibited phenotypic characters that were typical of the genus Rhodococcus. 16S rRNA gene sequence (1467 bases) comparisons confirmed that strain K07-23T belongs to the genus Rhodococcus. 16S rRNA sequence similarity studies showed ...

Introduction. The genus Rhodococcus is a non-sporeforming, high GC Gram-positive bacterium, a member of phylum Actinobacteria. Research studies for Rhodococcus have been mainly focused on its great ability to degrade recalcitrant chemicals such as poly-chlorinated biphenyls and dioxins (1, 2). Also, their pathogenic features have been intensively studied in limited species. However, only a few ...

Rieske nonheme iron oxygenases form a large class of aromatic ring-hydroxylating dioxygenases found in microorganisms. These enzymes enable microorganisms to tolerate and even exclusively utilize aromatic compounds for growth, making them good candidates for use in synthesis of chiral intermediates and bioremediation. Studies of the chemical stability and thermostability of these enzymes thus b...

The ability to generate tagged mutants of Rhodococcus spp. will facilitate a deeper understanding of this medically and commercially important genus. The absence of efficient transposon systems in these organisms has here been overcome by the use of Tn5-based DNA-protein transposition complexes which can transpose at high efficiency. To achieve this, electroporation efficiencies and antibiotic ...
