In all, 22 (27%) in the study group showed IgM levels above the arbitrarily selected limit of 2.40 g\/l, in contrast to 12 (13%) of 91 controls (p = 0.02). Among the study group members whose infants were infected with GBS type III, 8 of 34 (24%) were high in serum IgM, compared to only 2 of 34 (6%) of the corresponding controls (p = 0.04).
