  1. 21. Structural and functional studies of streptococcal surface adhesins

    Författare :Åsa Nylander; Karina Persson; Maria Selmer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The oral cavity is home to an array of microorganisms that are associated with dental plaque. Some Gram-positive bacteria are common inhabitants of the oral cavity and in order to colonize such a unique environment adhesion becomes essential and is accomplish by adhesins expressed on the bacterial surface.

    Sammanfattning : Functional immune modulation of macrophages play important role during bacterial infection. Neisseria meningitidis, a gram-negative diplococcal bacterium, is the leading cause of bacterial meningitis and fatal septic shock. However, it is also a commensal bacterium that colonizes the nasopharynx of healthy individuals asymptomatically. LÄS MER
