title: [Some aspects of virulence].
abstract: GLYCOPEPTIDE INTERACTION AND THE STAPHYLOCOCCI WALL: Glycopeptides induce modifications 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 Gram-negative germs is closely related to quorum sensing, a system regulated by bacterial inoculum. The use of strains deficient in different steps of quorum sensing in a experimental rat model has been useful in better understanding the pathophysiological effects linked to this system of virulence.
