Open AccessBacteria: back pain, leg pain and Modic sign—a surgical multicentre comparative study
To compare bacterial findings in pain-generating degenerated discs in adults operated on for lumbar disc herniation (LDH), and mostly also suffering from low back pain (LBP), with findings in adolescent patien...

Open AccessThe genome of Rhizobiales bacteria in predatory ants reveals urease gene functions but no genes for nitrogen fixation
Gut-associated microbiota of ants include Rhizobiales bacteria with affiliation to the genus Bartonella. These bacteria may enable the ants to fix atmospheric nitrogen, but no genomes have been sequenced yet to t...

Open AccessExtensive duplication of the Wolbachia DNA in chromosome four of Drosophila ananassae
Lateral gene transfer (LGT) from bacterial Wolbachia endosymbionts has been detected in ~20% of arthropod and nematode genome sequencing projects. Many of these transfers are large and contain a substantial part ...

Open AccessSingle-cell genomics reveal low recombination frequencies in freshwater bacteria of the SAR11 clade
The SAR11 group of Alphaproteobacteria is highly abundant in the oceans. It contains a recently diverged freshwater clade, which offers the opportunity to compare adaptations to salt- and freshwaters in a mono...

The ecological coherence of high bacterial taxonomic ranks
In this Opinion article, Laurent Philippot and colleagues argue that bacterial taxonomic ranks higher than species, such as the phylum, can show ecological coherence, and they discuss the implications of this ...

Evolutionary microbial genomics: insights into bacterial host adaptation
The wealth of genome data for host-adapted bacteria have made it possible to re-examine and quantify the level of integration between bacteria and their hosts.

Protein Evolutionary Rates Correlate with Expression Independently of Synonymous Substitutions in Helicobacter pylori
In free-living microorganisms, such as Escherichia coli and Saccharomyces cerevisiae, both synonymous and nonsynonymous substitution frequencies correlate with expression levels. Here, we have tested the hypothes...

The complete genome sequence of Francisella tularensis, the causative agent of tularemia
Francisella tularensis is one of the most infectious human pathogens known. In the past, both the former Soviet Union and the US had programs to develop weapons containing the bacterium. We report the complete ge...

The evolution of chronic infection strategies in the α-proteobacteria
The α-subdivision of the Proteobacteria is a very large and diverse group of Gram-negative microorganisms. They show great variability in metabolic capacities and inhabit diverse ecological niches. The authors...

Mitochondrial gene history and mRNA localization: is there a correlation?
Phylogenetic studies of the yeast mitochondrial proteome have shown a complex evolutionary scenario, in which proteins of bacterial origin form complexes with proteins of eukaryotic origin. Exciting new result...

Genome deterioration: loss of repeated sequences and accumulation of junk DNA
A global survey of microbial genomes reveals a correlation between genome size, repeat content and lifestyle. Free-living bacteria have large genomes with a high content of repeated sequences and self-propagat...

A LIM-homeodomain combinatorial code for motor-neuron pathway selection
Different classes of vertebrate motor neuron that innervate distinct muscle targets express unique combinations of LIM-homeodomain transcription factors1,2, suggesting that a combinatorial code of LIM-homeodomain...

The genome sequence of Rickettsia prowazekii and the origin of mitochondria
We describe here the complete genome sequence (1,111,523 base pairs) of the obligate intracellular parasite Rickettsia prowazekii, the causative agent of epidemic typhus. This genome contains 834 protein-coding g...

Codon usage and base composition inRickettsia prowazekii
Codon usage and base composition in sequences from the A + T-rich genome ofRickettsia prowazekii, a member of the alpha Proteobacteria, have been investigated. Synonymous codon usage patterns are roughly similar ...

ppGpp inhibition of elongation factors Tu, G and Ts during polypeptide synthesis
The inhibition of elongation factors G, Tu and Ts by ppGpp was studied in vitro in a translation system with missense frequency and elongation rate similar to those in vivo. ppGpp inhibits EF-G with KI=6x10-5 M. ...
