CLSM images of F. nucleatum subsp. polymorphum and S. gordonii infection of hGECs for 4 h F. nucleatum subsp. polymorphum and S. gordonii were stained green by CFSE. The cytoskeleton was stained red by phalloidin, and the nucleus was stained blue by DAPI. (A) Blank control group. (B) F. nucleatum subsp. polymorphum monoculture group (Fnp). (C) S. gordonii monoculture group (Sg). (D) F. nucleatum subsp. polymorphum and S. gordonii coinfection group (Fnp+Sg). (E) F. nucleatum subsp. polymorphum and S. gordonii coaggregation group (Fnp-Sg).
