  2. 11. Uncovering novel cell wall chemistries in gram negative bacteria : from development or dedicated peptidoglycan chemometric tools to functional genomics

    Author : Akbar Espaillat; Felipe Cava; Sun Nyunt Wai; Waldemar Vollmer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacteria; cell wall; peptidoglycan; peptidoglycan variations; D-amino acids; molekylärbiologi; Molecular Biology;

    Abstract : Bacteria are surrounded by an external cell wall whose main component is a polymeric net-like structure called the peptidoglycan (PG) or murein sacculus. PG plays crucial roles in bacterial physiology (eg morphogenesis, growth fitness and regulation of innate immunity). READ MORE

  4. 12. Pathogenecity-associated genes modulate Escherichia coli adhesion and motility

    Author : Annika E. Sjöström; Bernt Eric Uhlin; Ann-Beth Jonsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Escherichia coli strains typical of UPEC (uropathogenic E. coli) and NBM (newborn meningitis) isolates carry chromosomally located PAIs (pathogenicity islands) that are absent in non-pathogenic E. coli strains. The PAIs include genes for virulence factors such as toxins and genes coding for specific adhesins and pili/fimbriae formation. READ MORE
