A few notes on virulence

Glycopeptide interaction and the staphylococci wall: Glycopeptides induce m odifications in the cell wall of staphylococci. This modification has been observed in VISA strains and could involve bacterial adherence to materials . Quorum sensing: Bacterial virulence in Cram-negative germs is closely relat ed to quorum sensing, a system regulated by bacterial inoculum. The use of strains deficient in different steps of quorum sensing in an experimental r at model has been useful in better understanding the pathophysiological eff ects linked to this system of virulence.
