TIME-LAPSE CINEMATOGRAPHY OF VANCOMYCIN-TREATED MICROBIAL CELLS

Abstract
The incubation of Bacillus subtilis W23 or Bacillus cereus on a vancomycin-containing medium resulted in a rapid contraction or shrinkage of the cells which was followed by lysis. The ejection of protoplasm from the cell during lysis was very forceful. The "burst" of protoplasmic material was observed at the ends of the cell and at one or two sites on the lateral cell wall. The results are consistent with the hypothesis that vancomycin inhibits cell wall synthesis and ultimately destroys the normal structure and integrity of the wall.
