    A dual endosymbiosis supports nutritional adaptation to hematophagy in the invasive tick Hyalomma marginatum

    Marie Buysse, Anna Maria Floriano ... Olivier Duron
    The invasive tick Hyalomma marginatum relies on a dual partner nutritional system to provide B vitamins and avoid nutritional deficiencies due to its exclusive blood diet.

    A single mutation in Crimean-Congo hemorrhagic fever virus discovered in ticks impairs infectivity in human cells

    Brian L Hua, Florine EM Scholte ... Éric Bergeron
    Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.

    Longitudinal map of transcriptome changes in the Lyme pathogen Borrelia burgdorferi during tick-borne transmission

    Anne L Sapiro, Beth M Hayes ... Seemay Chou
    Development of an enrichment method to facilitate RNA-sequencing of the Lyme disease pathogen from inside of ticks during a bloodmeal provides new candidates for genes important for disease transmission.

    The Lyme disease agent co-opts adiponectin receptor-mediated signaling in its arthropod vector

    Xiaotian Tang, Yongguo Cao ... Erol Fikrig
    A new tick metabolic pathway that is connected to the survival of the Lyme disease spirochete was identified, which may lead to new ways to interfere with the spirochete life cycle.

    Acquisition of exogenous haem is essential for tick reproduction

    Jan Perner, Roman Sobotka ... Petr Kopacek
    The lack of haem biosynthetic and degradative pathways in ticks offers new strategies to combat these parasites.
