Modelling the effect of vaccines on cholera transmission Cholera is a gonorrheal disease that is caused by an intestinal bacterium, Vibrio cholerae. Recently an outbreak of cholera in Haiti brought public attention to this deadly disease. In this work, the goal of our differential equation model is to find an effective optimal vaccination strategy to minimize the disease related mortality and to reduce the associated costs.
Traitors in our midst: Bacteria use toxins to turn our own bodies against us Researchers who have revealed a highly efficient way that bacteria use toxins to interrupt the immune response say that until now, the trickery of these toxins has been underappreciated in science.
Bioengineers identify key genes, functions for sustaining microbial life A new study defines the core set of genes and functions that a bacterial cell needs to sustain life. The research, which answers the fundamental question of what minimum set of functions bacterial cells require to survive, could lead to new cell engineering approaches for E. coli and other microorganisms.
Chestnut leaves yield extract that disarms deadly staph bacteria The study of a chestnut leaf extract, rich in ursane and oleanene derivatives, shows that it that blocks Staphylococcus aureus virulence and pathogenesis without detectable resistance.
Discovery of trigger for bugs' defenses could lead to new antibiotics Scientists have exposed a chink in the armor of disease-causing bugs, with a new discovery about a protein that controls bacterial defenses
