11. Pathogenecity-associated genes modulate Escherichia coli adhesion and motility
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

12. Roles of secreted bacterial factors in modulation of host cell signalling
Abstract : Pathogenic bacteria employ several secretion systems to release or inject virulence factors that may alter host cell processes, generate a replicative niche, and aid bacterial survival in adverse environments. This thesis presents my investigations on how bacterial factors can modulate host cell signalling mechanisms. READ MORE

13. Roles of membrane vesicles in bacterial pathogenesis
Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

14. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms
Abstract : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. READ MORE
