Effect of inoculum sizes on the bactericidal activity of cord serum (CS) and adult serum (AS). Various inoculum sizes of OmpA+ (E44), OmpA− Escherichia coli (E91), wild-type Group B Streptococci (wt-GBS), or acapsular GBS (acap-GBS) ranging from 104 to 106 colony- forming units were subjected to serum bactericidal assay for the times indicated. Aliquots of the bacteria in serum were then serially diluted and plated on blood agar. The experiments were performed in triplicate, at least three times with the data representing relative survival with the bacterial survival at 0 min set as 100%. Error bars represent ± SD.
