    Immune genes are hotspots of shared positive selection across birds and mammals

    Allison J Shultz, Timothy B Sackton
    Pathogens, particularly viruses, target the same genes over deep evolutionary time, resulting in shared signatures of positive selection and transcriptional responses at the same genes.

    Severe infections emerge from commensal bacteria by adaptive evolution

    Bernadette C Young et al.
    Life-threatening S. aureus infections emerge from commensal nose bacteria in association with repeatable adaptive evolution.

    Eighteenth century Yersinia pestis genomes reveal the long-term persistence of an historical plague focus

    Kirsten I Bos et al.
    The analysis of 18th century Y. pestis genomes reveals a bacterial lineage that might be responsible for the 400-year period of European plague epidemics from the Renaissance through early modern times.

    Transmission dynamics and control of multidrug-resistant Klebsiella pneumoniae in neonates in a developing country

    Thomas Crellen et al.
    Colonisation with resistant Klebsiella pneumoniae in a Cambodian neonatal unit is driven by person-to-person transmission, transmissibility varies by sequence type, and antibiotic consumption generally increases the risk of acquisition.

    Species-wide whole genome sequencing reveals historical global spread and recent local persistence in Shigella flexneri

    Thomas R Connor et al.
    Shigella flexneri, globally the most frequent cause of bacterial dysentery, is far more diverse, and has caused disease around the world for far longer than other Shigella species by persisting in local environments over extended timescales.

    Rare missense variants in the human cytosolic antibody receptor preserve antiviral function

    Jingwei Zeng et al.
    Studying the impact of natural variation on a key immune gene highlights how focusing on a single wild-type sequence overlooks that rare variants cause the most disease.

    Global genome diversity of the Leishmania donovani complex

    Susanne U Franssen et al.
    Genomic data for the parasites that cause visceral leishmaniasis provides the first global picture of the diversity and evolution of the pathogen and the epidemiology of this fatal tropical disease.

    Bile salt receptor complex activates a pathogenic type III secretion system

    Peng Li et al.
    Microbial genetics and biophysical analyses provide insight into an evolutionarily conserved bile salt receptor complex used by pathogenic bacteria to sense their environment.

    Previously undetected super-spreading of Mycobacterium tuberculosis revealed by deep sequencing

    Robyn S Lee et al.
    Incorporating within-host diversity in transmission, as identified by deep sequencing, can significantly change previously-held inferences, with major implications for genomic studies of transmission in tuberculosis and other pathogens as well.

    Targeted surveillance strategies for efficient detection of novel antibiotic resistance variants

    Allison L Hicks et al.
    Sampling informed by pathogen genomic data may facilitate more efficient detection of novel antibiotic resistance than random sampling.
