In this study, Fackelmann et al. show that microplastics impair the gastrointestinal microbiome of two seabird species.

In this study, Lubin et al. show that an immature microbiome during weaning affects the development of the immune system and increases the risk of enteric infections in mice.

In this study, Kreitz et al. examine a bacterial extracellular contractile injection system that can deliver diverse proteins into different target cells.

In this study, Stubbendieck et al. show that commensal bacteria Rothia spp. inhibit the growth of the nasal pathobiont Moraxella catarrhalis.

This study reports a mechanism of norovirus-induced cell death that promotes viral egress.

A recent study reports that uropathogenic Escherichia coli infection triggers trained immunity in urinary tract tissue, which affects the immune response to subsequent infections.

This study investigated the environmental microbiomes of cities by sampling urban beehives, providing insight into the surrounding metagenomic landscape that is relevant to beehive and human health.

This Genome Watch highlights recent metagenomics studies in fish that reveal unique microbiomes with low functional diversity, which could help to improve our understanding of host–microorganism dynamics in non-mammalian species.

In this Review, Caballero-Flores, Pickard and Núñez explore how the microbiota limits colonization by pathogens and the strategies used by pathogens to counter colonization resistance.

In this Review, Markov, Katzourakis and colleagues explore the evolution of SARS-CoV-2 at different scales, the phases of the COVID-19 pandemic, factors that drive the evolution of the virus, theories for the emergence of epidemiologically important variants and potential future evolutionary scenarios and their likely health repercussions.

In this Review, Howden and co-workers examine and integrate recent key advances in understanding the mechanisms that Staphylococcus aureus uses to cause infections.

In this Review, Kim and Diamond highlight recent advances in our understanding of the host factors required for alphavirus entry, the mechanisms of action by which protective antibodies inhibit different steps in the alphavirus infection cycle and candidate alphavirus vaccines currently under clinical evaluation.
