A flat embedding method for transmission electron microscopy reveals an unknown mechanism of tetracycline

Abstract

Wenzel et al. developed a flat embedding method for TEM, which increases the fraction of appropriately orientated cells per image, making it easier to quantify cell morphology. They find that tetracycline-treated B. subtilis shows membrane lesions and that tetracycline action is via direct perturbation of bacterial cell membrane in addition to its known ribosome inhibition activity.
