Loss of both K and O antigens (K−O−), but not the K antigen alone (K−O+), increased surface hydrophobicity and susceptibility to phagocytosis. Unheated serum (i.e., containing complement) increased the surface hydrophobicity and phagocytosis of the K−O+ and K−O− strains, but not of the K+O+ encapsulated parent strain. Despite the altered susceptibility to phagocytosis caused by the presence or absence of the K and O antigens, their loss did not influence sensitivity to a range of hydrophilic, hydrophobic or cationic antimicrobial agents.", }
