    Intestinal infection with adherent-invasive Escherichia coliis associated with Crohn’s disease in humans; however, its functional role remains unclear, in part due to a lack of animal models, which sustain chronic disease. Here the authors establish such a model in mice and show that it shares features with human Crohn’s disease.

    Influenza A viruses spread through contact, large and small respiratory droplets (aerosols), but the relative importance of these modes of transmission is unclear. Cowling et al. model data from community trials of face masks and hand hygiene and find that aerosol transmission accounts for half of influenza occurrences.

    Transmission-blocking interventions aim to interrupt progression of Plasmodium parasites from the vertebrate host to the mosquito. Blagborough et al. demonstrate that only partially reducing transmission can be sufficient to eliminate experimental Plasmodiuminfection in successive mosquito and mice populations when biting rates are low.

    The number of human infections caused by the primate malaria parasite P. knowlesi is increasing. Lim et al. demonstrate that host specificity is due to the preference of the parasite for young blood cells, and that the parasite can adapt to proliferate in human blood containing a range of differently aged cells.

    Exposure to malaria during pregnancy can result in its spread to the placenta; however, the risk of placental infection decreases with subsequent pregnancies. By constructing a mathematical model, the authors find that this is likely due to a reduction in the duration of infection rather than a reduced risk of transfer.

    A variant in the IFITM3gene increases the risk of severe influenza, but homozygosity is rare in Caucasians. The authors show that the variant gene is homozygous in 25% of healthy Chinese people, and 69% of those with severe pandemic influenza, suggesting that this gene influences the epidemiology of influenza in South-East Asia.

    The proteome of the malarial parasite Plasmodium falciparum has an overabundance of aggregation-prone asparagine repeat-containing proteins. Muralidharan et al. show that PlasmodiumHsp110 protein potently prevents aggregation of asparagine-rich proteins, thereby allowing the parasite to survive febrile episodes.

    Knowledge of how a disease spreads can lead to useful predictions to help manage and contain it. Here, Maher et al.model white-nose syndrome spreading in North American bats, and show that concentrated habitat distribution and longer winters can mediate pathogen dispersal, matching the ecological traits of bats.

    Malaria can persist at levels that escape detection by standard microscopy, but can be detected by PCR. Okell et al.now show that rates of submicroscopic infection can be predicted using more widely available microscopy data, and are most epidemiologically significant in areas with low malaria transmission.

    The incidence of bovine tuberculosis in the UK is increasing despite efforts to eradicate the disease. The authors of this paper show that infection of cattle with the parasiteFasciola hepaticaimpedes the diagnosis of tuberculosis, which may in part explain why the current eradication campaign is failing.

    Lung injury initiates a series of wound-healing responses, which if unregulated, can lead to fibrosis. Liet al. show that the deubquitinase CYLD has a key role in the prevention of fibrosis by inhibiting transforming growth factor β-signalling through the direct deubiquitination of the protein kinase Akt.

    It is unclear whether pathogens can advantageously exploit the host's immune response. UsingCandida albicans, the authors show that host IL-17A binds to the fungi and induces nutrient starvation and autophagy, which eventually leads to enhanced biofilm formation and resistance to the hosts' defence.

    Spatial epidemiology studies identify malaria hotspots, which sustain transmission and so could be targeted by control programmes. This study uses spatial data on larval sites and malaria episodes to show that transmission can be disrupted by targeting vector breeding sites close to and downwind of malaria hotspots.

    Epitopes presented by MHC-II molecules bind to T-cell receptors to activate CD4+ T cells. In this study, changes in the carboxy-terminal region of the influenza hemagglutinin epitope HA305-320alters the strength of binding to the T-cell receptor, thus modulating T-cell receptor usage and activation.

    In vertebrates parasite-mediated selection is thought to maintain polymorphism in MHC genes where specific resistance MHC alleles increase under emerging selection. Here, experimental evidence is shown from six stickleback fish populations that varying parasite selection helps maintain MHC polymorphism.

    Studying how pathogens enter polarized epithelial cells is important for understanding infection. Here, activation of chemokine receptors on the apical membrane of epithelial cells, is shown to engage Src family tyrosine signalling, resulting in relocation of the viral co-receptor αvβ3 to the apical membrane and adenovirus entry.

    Sixty years ago it was suggested that the sickle cell disease mutation survives because the heterozygous genotype confers resistance to malaria, resulting in correlation of the two geographical distributions. The authors use a new global assembly of sickle allele frequencies to support this hypothesis at the global scale.
