Antibiotic persistence is a threat to effective treatment of bacterial infections. In this Review, Bakkeren, Diard and Hardt discuss the evolutionary forces that have favoured the development of persisters in populations and the consequences for spread of resistance and virulence determinants.

In this Review, Ruff, Greiling and Kriegel discuss the mechanisms through which the microbiota contributes to the predisposition, initiation and perpetuation of immune-mediated diseases, and explore the therapeutic avenues that either target the microbiota, the barrier surfaces or the host immune system to restore tolerance and homeostasis.

In this Review Egan, Errington and Vollmer discuss new insights into the molecular mechanisms of peptidoglycan synthesis, sacculus growth regulation and bacterial morphology, as well as how bacteria achieve robust cell wall growth under different conditions and stresses.

The schooner Tara sailed 140,000 km across the global oceans to sample diverse marine ecosystems and plankton communities. In the Review, members of the Tara Oceans project highlight how resulting data can be used for an integrated understanding of ocean biology.

Filoviruses such as Ebola virus pose a substantial health risk to humans. Advances in genomic technologies have enabled the rapid, large-scale generation of virus sequence data at the location of disease outbreaks and thus the use of reverse functional genomics to swiftly characterize the threat of, and treatment for, filovirus disease.

In this Review, Jones and colleagues describe the extremely diverse Xanthomonas spp. and how these plant pathogens use their extensive repertoire of effectors for virulence and immune evasion. Understanding these prototypical plant pathogens paves the way to combat disease.

New antibacterial agents are urgently needed to address the global increase in resistance. In this Review, Theuretzbacher and colleagues critically review the current published literature and publicly available information on antibacterial agents in all phases of clinical development.

Worldwide amphibian declines caused by pathogenic chytrid fungi are emblematic of the emerging infectious diseases driven by globalization. Fisher and Garner discuss how these wildlife pathogens emerge to drive global declines in amphibian biodiversity and the implications of current research for policy and control measures.

Non-tuberculous mycobacteria, such as Mycobacterium abscessus, are an increasing global health burden, in part due their extensive drug resistance. In this Review, Johansen, Herrmann and Kremer discuss the infection process, host interactions, mechanisms of drug resistance and drug development.

In this Review, Klein and Hultgren discuss recent advances in our understanding of the interplay between pathogens and the host during urinary tract infections, and how the insights into host–pathogen interactions and pathogenesis are guiding the development of antibiotic-sparing therapeutics.

In this Review, Hatzenpichler et al. introduce next-generation physiology, which is a suite of new techniques that enable investigation into the phenotypes of individual cells in a non-destructive manner. Next-generation physiology complements genomics and culturing and provides new insights into microbiome function.

Over the past decade, Klebsiella pneumoniae has emerged as a major clinical and public health threat. In this Review, Wyres, Lam and Holt discuss how genomics approaches have advanced our understanding of K. pneumoniae taxonomy, ecology and evolution as well as the diversity and distribution of clinically relevant determinants of pathogenicity and antimicrobial resistance.

In this Review, van Belkum and colleagues discuss routinely used antimicrobial susceptibility testing (AST) methods, explore current efforts to improve phenotypic AST systems — including new emerging technologies as well as genomic and gene-based antimicrobial resistance detection methods — and highlight the challenges and opportunities for new rapid AST systems.

In this Review, Berman and Krysan define and distinguish resistance and tolerance, and discuss the current understanding of the molecular, genetic and physiological mechanisms that contribute to those phenomena. Distinguishing tolerance from resistance might provide important insights into the reasons for treatment failure in some settings.

Phages are tremendously abundant and are found in every environment where bacteria exist. In this Review, Dion, Oechslin and Moineau explore the diversity of phages at the structural, genomic and community levels as well as their complex evolutionary relationships.

Bacteria produce diverse polymers, such as polysaccharides, polyesters, polyphosphates and extracellular DNA. In this Review, Moradali and Rehm discuss the types of bacterial polymers and their role in bacterial physiology and pathogenesis as well as their production and use as novel biomaterials.

During intraerythrocytic development, malaria parasites replicate within a membrane-bound parasitophorous vacuole. In this Review, Matz, Beck and Blackman explore the origin, development, molecular composition and functions of the parasitophorous vacuole during blood-stage development. They also discuss the relevance of the malaria parasite’s intravacuolar lifestyle for successful erythrocyte infection and provide perspectives for future research directions.

Microbiology and biophysics are converging to advance our understanding of the mechanobiology of microorganisms. In this Review, Dufrêne and Persat discuss the physical forces that bacteria experience in their natural environments and the structures that transmit these forces to a cell. Furthermore, they explore bacterial phenotypes influenced by mechanical inputs, including adhesion, motility and biofilm formation.

Plastic debris in the marine environment provides a durable substrate that can be colonized by microorganisms and supports the growth of microbial biofilms. In this Review, Amaral-Zettler and colleagues explore the microbial ecology of the plastisphere in the context of its diversity and function, as well as suggesting areas for further research.

Plasmodium falciparum and other malaria parasites have complex life cycles, inhabiting different host cells and tissues during their multistage development. In this Review, Marti and colleagues discuss blood-stage parasite development and the newly discovered reservoir in the haematopoietic niche.
