  1. 1. The Salmonella enterica virulence : its role in bacterial adaption to mammalian and protozoan cells

    Author : Dilek Tezcan-Merdol; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Salmonella virulence plasmid; spvB gene; mono ADP-ribosyl transferase; actin; Acanthamoeba rhysodes;

    Abstract : Salmonellae are Gram-negative enteric bacteria and facultative intracellular pathogens responsible for a diversity of illnesses in a wide range of hosts, including man. Many serovars of Salmonella enterica harbor a plasmid that enhances bacterial virulence in infection models, and that seems to promote extraintestinal infection in man. READ MORE

  2. 2. Studies on the coiled-coil protein TlpA in salmonella : a thermosensing transcription autoregulator

    Author : Reini Hurme; Karolinska Institutet; Karolinska Institutet; []
    Keywords : coiled-coilgene regulationrepressorthermoregulationSalmonella;

    Abstract : The coiled-coil motif is composed of amino acid heptad repeats with hydrophobic or apolar residues at conserved positions. Such repeats are responsible for the apolar stripe that is buried inside the coiled-coil structure formed upon coiling of two (or more) alpha-helical chains about each other. READ MORE
