FIG 2.

GBS association with host cells. Host cell lines were infected with GBS at a multiplicity of infection (MOI) of 1 for 2 h. The number of bacteria is expressed relative to the total number of bacteria in the well after the infection. (A and B) Attachment to (A) and invasion of (B) decidual cells. (C and D) Attachment to (C) and invasion of (D) lung epithelial cells. Bars represent means ± SD of the results. Bars labeled with different letters are significantly different from each other. Experiments were repeated in triplicate at least three times.
