Molecular Identification and Metagenomics Using Complete Mitochondrial Genomes

Researchers sorely need markers and approaches for biodiversity exploration (both specimen linked and metagenomics) using the full potential of next generation sequencing technologies (NGST). Currently, most studies rely on expensive multiple tagging, PCR primer universality and/or the use of few markers, sometimes with insufficient variability. We propose a novel approach for the isolation and sequencing of a universal, useful and popular marker across distant, non-model metazoans: the complete mitochondrial genome.

Quality of mammoth mitogenomes from different high-throuput DNA sources

by Régis Debruyne Published abstract With the rise of the second generation techniques of sequencing, the illusion has spread that the sequence data produced in the field of paleogenetics/paleogenomics would soon become error-free. It has repeatedly been claimed that the new methods available were more « performant » than their predecessors to overcome the inherent…

Antibiotic resistance is ancient

The discovery of antibiotics more than 70 years ago initiated a period of drug innovation and implementation in human and animal health and agriculture. These discoveries were tempered in all cases by the emergence of resistant microbes. This history has been interpreted to mean that antibiotic resistance in pathogenic bacteria is a modern phenomenon; this view is reinforced by the fact that collections of microbes that predate the antibiotic era are highly susceptible to antibiotics.
