Comment: Categorization of the gut microbiota: enterotypes or gradients? Ian B. Jeffery, Marcus J. Claesson, Paul W. O'Toole & Fergus Shanahan p591 | doi:10.1038/nrmicro2859 Grouping the microbiota of individual subjects into compositional categories, or enterotypes, based on the dominance of certain genera may have oversimplified a complex situation.

RESEARCH HIGHLIGHTS
| Top | Bacterial pathogenicity: Targeting translation p593 | doi:10.1038/nrmicro2870 The insect pathogen Pseudomonas entomophila arrests host protein synthesis in the gut of its Drosophila melanogaster host. PDF
Bacterial pathogenesis: The two faces of P. luminescens p594 | doi:10.1038/nrmicro2851 Promoter inversion mediates the switch from a mutualistic to a pathogenic form of P. luminescens. PDF
Antimicrobials: Arming symbionts with antimalarials p594 | doi:10.1038/nrmicro2860 A bacterial symbiont of mosquitoes, genetically engineered to secrete antiparasitic effector proteins, arrests the development of Plasmodium spp. in these vectors. PDF
IN THE NEWS New TB drug cocktail p594 | doi:10.1038/nrmicro2864 A promising new treatment regimen, consisting of three drugs administered in combination, offers renewed hope in the battle against tuberculosis. PDF
Viral infection: Coaxing HIV out of hiding p596 | doi:10.1038/nrmicro2861 Two studies suggest that using inhibitors of histone deacetylases to reactivate latent HIV-1 is a realistic route to coaxing the latent virus out of its genomic hiding place. PDF

Genome Watch: Natural transformers Claire Chewapreecha p598 | doi:10.1038/nrmicro2865 This month's Genome Watch highlights in natura cases showing the role of recombination in bacterial evolution, and in vitro studies that focus on the mechanisms of recombination. PDF

Focus on: Next-generation sequencing | PROGRESS | Top | High-throughput bacterial genome sequencing: an embarrassment of choice, a world of opportunity Nicholas J. Loman, Chrystala Constantinidou, Jacqueline Z. M. Chan, Mihail Halachev, Martin Sergeant, Charles W. Penn, Esther R. Robinson & Mark J. Pallen p599 | doi:10.1038/nrmicro2850 In this Progress article, Pallen, Loman and colleagues present a snapshot of the high-throughput sequencing platforms available to microbiologists today, together with the relevant analytical tools, and evaluate their strengths and weaknesses in obtaining bacterial genome sequences. Abstract | Full Text | PDF | Supplementary information
| REVIEWS | Top | Going viral: next-generation sequencing applied to phage populations in the human gut Alejandro Reyes, Nicholas P. Semenkovich, Katrine Whiteson, Forest Rohwer & Jeffrey I. Gordon p607 | doi:10.1038/nrmicro2853 Viruses are the most diverse and uncharacterized components of all the major ecosystems on Earth, including that within the mammalian gut. Here, Gordon and colleagues review our current understanding of the diversity and ecology of the bacteriophages present in the human gut and discuss how an improved understanding of phage dynamics could revitalize phage therapy. Abstract | Full Text | PDF
| Dual RNA-seq of pathogen and host Alexander J. Westermann, Stanislaw A. Gorski & Jörg Vogel p618 | doi:10.1038/nrmicro2852 The infection process is accompanied by widespread changes in gene expression in both host and pathogen. Here, Vogel and colleagues explore the feasibility of simultaneously analysing the transcriptomes of both host and pathogen using RNA deep-sequencing approaches. Abstract | Full Text | PDF | Supplementary information
| Genomic sequencing of uncultured microorganisms from single cells Roger S. Lasken p631 | doi:10.1038/nrmicro2857 In recent years, thanks to the development of whole-genome amplification methods, it has become possible to sequence the genome of a single bacterial cell. Here, Roger Lasken reviews the development of single-cell sequencing techniques and their most recent applications. Abstract | Full Text | PDF

Genomic insights into the marine sponge microbiome Ute Hentschel, Jörn Piel, Sandie M. Degnan & Michael W. Taylor p641 | doi:10.1038/nrmicro2839 Marine sponges can contain dense and diverse microbial communities that can constitute up to 35% of the sponge biomass. In this Review, Hentschel and colleagues describe how genomic insights into both sponges and their associated microbiota are beginning to illuminate the functional and evolutionary roles of each partner in this association.

Microbial translocation in HIV infection: causes, consequences and treatment opportunities Netanya G. Sandler & Daniel C. Douek p655 | doi:10.1038/nrmicro2848 Even when receiving antiretroviral therapy, HIV-infected individuals have an increased risk of mortality owing to systemic immune activation. Sandler and Douek review evidence showing that the translocation of microbial products from the intestine into the circulation may contribute to this risk and discuss potential therapeutic strategies.
