Scanning electron photomicrographs showing interaction of bMECs infected withS. agalactiae. A Untreated bMECs; BS. agalactiae (arrow); C cell shrinkage and slight bulging at 2Â h. D Microvilli trapping S. agalactiae at 2Â h (arrows). E A cell with folded edge (thick arrow) and microvilli extending and wrapping S. agalactiae (thin arrow) at 4Â h. F Cell fracture at 4Â h; G cells with obvious shrinkage, dysmorphosis, desquamation and microvilli disappearance (thin arrow) at 6Â h; HS. agalactiae secrete substances that adhere to the cell surface at 6Â h (arrow); and I cell membrane breakage at 8Â h.
