FIG 3.
PEMF reduce the number of surface-adhered S. epidermidis biofilm cells. Shown are SEM images of S. epidermidis grown on a cell culture-treated, polystyrene, 24-well plate. (A to C) S. epidermidis ATCC 14990; (D to F) S. epidermidis ATCC 35984. Panels A and D show the control, which was S. epidermidis that was not exposed to PEMF or vancomycin. Panels B and E show S. epidermidis after 24 h of PEMF exposure. Panels C and F show S. epidermidis after 24 h of PEMF exposure and simultaneous vancomycin treatment.
