    As certain phages can infect some Pseudomonas aeruginosa strains by binding to their pilins, the bacteria have evolved ways to modify these structures via the addition of O-antigen units or polymers of d-arabinofuranose to block phage attachment.

    How the oral epithelium discriminates pathogens from commensals is unclear. Ephrin A2 is now shown to bind exposed β-glucans on the surface of the fungal pathogen Candida albicans, which is required to mount a proinflammatory and antifungal response.

    To evade autophagy-mediated killing when inside liver cells, the Plasmodium berghei protein UIS3 binds to a key regulator of the autophagy programme, the host protein LC3, and inhibits its interaction with downstream effectors.

    Cultivation of a cellulolytic consortium reveals successional community dynamics and the presence of multidomain glycoside hydrolases assembled into stable complexes distinct from cellulosomes, which are produced by a potential pioneer population.

    This study reports the viral and cellular N 6-methyladenosine (m6A) and N 6,2′-O-dimethyladenosine (m6Am) epitranscriptomes during KSHV latent and lytic infection, and shows that lytic replication induces dynamic epitranscriptome reprogramming of host pathways that control this process.

    The cell tropism of noroviruses in vivo remains unclear. Here, the dominant cellular targets during acute norovirus infection of immunocompetent mice are shown to be macrophages, dendritic cells, B cells and T cells in the GALT gut-associated lymphoid tissue.

    Adaptation of the polony method allows numerical abundances of diverse viral groups to be quantified in environmental samples, and reveals that clade B T7-like cyanophages that carry the <Emphasis Type=”Italic”>psbA</Emphasis> gene are more abundant in the Red Sea than clade A phages.

    The Uncultivated Bacteria and Archaea dataset is a foundational collection of 7,903 genomes from uncultivated microorganisms. It highlights how microbial diversity is readily recovered using current tools and existing metagenomic datasets to help piece together the tree of life.

    An increased focus on identifying disease hotspots and pre-emptive intervention will be key to halting outbreaks before they become established, but political and economic obstacles cannot be ignored if ambitious new targets to reduce global cholera mortality tenfold are to be achieved.

    Two studies identify circulating monocytes as the primary cellular target of Zika virus infection in human blood. Monocytes are an ideal target as they have the potential to be used as a Trojan horse to infiltrate immune-sheltered tissues, including placenta, testes and the brain, to spread Zika virus.
