Helix handedness of Leptospira interrogans as determined by scanning electron microscopy

Comparative Study

Helix handedness of Leptospira interrogans as determined by scanning electron microscopy

O Carleton et al. J Bacteriol. 1979 Mar.

Abstract

Representative serovars and strains of the seven genetic groups of Leptospira interrogans, and two previously studied serovars, were all found to form exclusively right-handed helices as determined by scanning electron microscopy. No change in handedness occurred in cells grown in a minimal medium (Tween-80 albumin) compared to cells grown in a rich medium (rabbit serum). The right-handedness of the organisms was related to the evolution, cell wall structure, and the mechanism of motility of L. interrogans.
