1. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia
Sammanfattning : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. LÄS MER
2. Controlling virulence in Yersinia pseudotuberculosis through accumulation of phosphorylated CpxR
Sammanfattning : Like many Gram-negative bacteria, the food-borne pathogen Yersinia pseudotuberculosis harbours different regulatory mechanisms to maintain an intact bacterial envelope especially during exposure to extracytoplasmic stress (ECS). The CpxA-CpxR two component regulatory system is one such ECS-responsive regulatory mechanism. LÄS MER
3. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A
Sammanfattning : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. LÄS MER
4. Molecular mechanism of plasmid copy number control in Yersinia
Sammanfattning : The ability of pathogenic bacteria to cause disease depends on various virulence mechanisms. The three pathogenic species of Yersinia use a type III secretion system (T3SS) to translocate effector proteins into host cells and disrupt the immune system. This T3SS is encoded on a 70kb, low-copy, virulence plasmid. LÄS MER
5. The Salmonella enterica virulence : its role in bacterial adaption to mammalian and protozoan cells
Sammanfattning : 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. LÄS MER
