Abstract
The susceptibility ofEscherichia coli strains with K1 surface antigen (K1+) and rods without this antigen (K1−) to the bactericidal action of normal bovine serum and human normal cord serum was determined. SeventyE. coli strains (35 K1+ and 35 K1−) were isolated from urine obtained from children with urinary tract infections. The strains investigated showed variable sensitivity to the bactericidal action of the sera.E. coli K1+ strains were characterized by lower sensitivity to bactericidal effect of the sera in comparison with K1− rods. The role of the particular mechanisms of complement activation in the process of killing of theE. coli strains was also determined.
