Because of their beneficial impact on plants, the highly diverse mycorrhizal fungi grouped in the order Sebacinales lay claim to high ecological and agricultural significance. Here, we describe for the first time associations of Sebacinoid members with bacteria. Using quantitative PCR, denaturating gradient gel electrophoresis and fluorescence in situ hybridization, we detected an intimate asso...

Many endophytic bacteria exert beneficial effects on their host, but still little is known about the bacteria associated with plants growing in areas heavily polluted by hydrocarbons. The aim of the study was characterization of culturable hydrocarbon-degrading endophytic bacteria associated with Lotus corniculatus L. and Oenothera biennis L. collected in long-term petroleum hydrocarbon-pollute...

A Gram-positive, aerobic, non-motile, mesophilic strain, designated YIM 70056(T), was isolated from a forest soil sample in Yunnan Province, China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that this isolate had less than 97.0 % similarity to any Rhodococcus species with validly published names, with the exception of Rhodococcus fascians (DSM 20669(T)), which was found to ...

The taxonomic relationships of two actinomycetes provisionally assigned to the genus Rhodococcus were determined using a polyphasic taxonomic approach. The generic assignment was confirmed by 16S rRNA gene similarity data, as the organisms, strains MTCC 1534 and W 4937(T), were shown to belong to the Rhodococcus rhodochrous subclade. These organisms had phenotypic properties typical of rhodococ...

Cultureable bacterial diversity of previously unexplored Siachen glacier, Pakistan, was studied. Out of 50 isolates 33 (66%) were Gram negative and 17 (34%) Gram positive. About half of the isolates were pigment producers and were able to grow at 4-37°C. 16S rRNA gene sequences revealed Gram negative bacteria dominated by Proteobacteria (especially γ-proteobacteria and β-proteobacteria) and Fla...

The abundance, identities, and degradation abilities of indigenous polychlorinated biphenyl (PCB)-degrading bacteria associated with five species of mature trees growing naturally in a contaminated site were investigated to identify plants that enhance the microbial PCB degradation potential in soil. Culturable PCB degraders were associated with every plant species examined in both the rhizosph...

BACKGROUND Rhodococcus species are relatively rare human pathogens, but are being increasingly recognized as causes of infection especially in immunosuppressed patients. CASE REPORT We present a case of Rhodococcus lung abscess in a patient 10 months post-cadaveric renal transplant, successfully treated with a combination of antibiotics. She required a prolonged course of oral antibiotics for...

Rhodococcus erythropolis strain R138 was isolated from the rhizosphere of Solanum tuberosum and selected for its capacity to degrade N-acyl-homoserine lactones, quorum-sensing signals used as communication molecules by the potato pathogens Pectobacterium and Dickeya. Here, we report the genome sequence of Rhodococcus erythropolis strain R138.

pAL5000 based vectors, conventionally used to transform Mycobacterium species were used in this study to transform Rhodococcus and Gordonia species. Adequate transformation efficiencies were obtained ranging between 4.5x10 3 – 2.8x10 6 . Additionally, a pAL5000 based vector with suicide function was generated. This vector was transformed into Rhodococcus, Mycobacterium and Gordonia species and ...

BACKGROUND Infectious diseases of wildlife are increasing worldwide with implications for conservation and human public health. The microbiota (i.e. microbial community living on or in a host) could influence wildlife disease resistance or tolerance. White-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans (Pd), has killed millions of hibernating North American bats since 20...
