saprophite microorganisms are beneficial, but for some, their virulence may be harmful. can we inhibit virulence factors without destroying microbial cells ?
If some of those virulence factors are under control of quorum sensing mechanisms, certainly you can inhibit their expression through quorum quenching molecules keeping cells alive
Yes you can. If we know for example metabolic way on how a toxin is synthetized we can target an enzyme responsible for it production. It is demonstrated that statin used in human medecin for traitment of hypercholestrol could inhibite production of the golden pigment of S. aureus making it no virulent
