Figure 1: Adhesion of N.meningitidis in glioblastoma cells line NG97 stained by Giemsa. The line arrows indicate the glioblastoma cells altered by meningococcal adhesion. In (A) the negative control show the NG97 cells line, in (B): the adhesion (line arrow) and morphologic alterations caused by C2135 infection, also detected cytoplasmatic projections called ble’s (black arrows). In C the strain W135 such not show cellular alterations after infection; In (D) the strain P2143; (E): IAL 2443 and (F): Y USA. All these meningococci adhesions showed morphologic alterations with bleb’s formation. Amplification of 1000X.
