  1. 1. Chemical genetics discloses the importance of heme and glucose metabolism in Chlamydia trachomatis pathogenesis

    Författare :Patrik Engström; Sven Bergström; Ted Hackstadt; Umeå universitet; []
    Nyckelord :Chlamydiae; heme metabolism; glucose metabolism; glucose-6-phosphate; RB-to-EB transition; molekylärbiologi; Molecular Biology;

    Sammanfattning : Chlamydiae are important human bacterial pathogens with an intracellular life cycle that consists of two distinct bacterial forms, an infectious form (EB) that infects the eukaryotic host cell, and a non-infectious form (RB) that allows intracellular proliferation. To be successful, chlamydiae need to alternate between EB and RB to generate infectious EB’s which are competent to infect new host cells. LÄS MER
