| Abstract: | K31 antigen is the important element of outer membrane in resistance of E. coli H209 to the bactericidal activity of normal rabbit serum. The strains more resistant to the effect of serum are those containing simultaneously K31 and other factors, R plasmids (like R100. 1 and pAM588-Ia) or virulence plasmids (Vir). Mutant strains lacking of K31 antigen are strongly killed by the serum but this effect is delayed when these strains had one of the above plasmids. |
