Abstract
We report a metagenomic analysis of a healthy human plaque sample using a combination of second-generation sequencing platforms. A total of 860 million base pairs of non-human sequences were generated. Various analysis tools revealed the presence of 12 well-characterized phyla, members of the TM-7 a...

Journal of Antibiotics (63)11 2010
Abstract
We identified 12 strains capable of efficient hydroxylation. Results of phylogenetic analysis of 16S rDNA sequences suggested that these strains belonged to the genera Lentzea, Saccharopolyspora, Sphaerisporangium and Amycolatopsis. Morphological and chemical characteristics as well as results of ph...

Abstract
Staphylococcus aureus is now amongst the most important pathogenic bacteria responsible for bloodstream nosocomial infections and for biofilm formation on indwelling medical devices. Its increasing resistance to common antibiotics, partly attributed to its ability to form biofilms, is a challenge fo...
