The Power of Bacteria: describe the mechanisms used by gram-positive bacteria to retain proteins on their cell surfaces.why are these mechanisms needed.

The Power of Bacteria Describe how you would show that putative translocated effector proteins from Salmonella were involved in inducing actin rearrangements, changing phosphorylation states of host proteins, and induction of apoptosis or DNA synthesis in host cells. In the chapter, we mention that one advantage of direct delivery of toxic effectors into target host … Read more

The Power of Bacteria: the genomes of a number of bacterial pathogens have now been completely sequenced. How might the availability of this information affect the definition of virulence factors?

The Power of Bacteria The genomes of a number of bacterial pathogens have now been completely sequenced. How might the availability of this information affect the definition of virulence factors? Why are in vivo expression technologies continuing to turn up housekeeping genes rather than the “virulence genes” the researchers who developed these methods originally envisioned? … Read more
