The Genus Stella

  • Peter Hirsch
  • Heinz Schlesner


Flat bacteria have only rarely been described: in the genera Simonsiella and Alysiella (this Handbook, Chapter 23), the “cells are arranged in apposition to form filaments which are flat, not cylindrical” (Steed-Glaister, 1974). Evidently, the flat shape is constant. Bacteria of the genus Stella (Vasiljeva, 1970) are new examples of flat cells; in natural samples they resemble flat, six-pronged stars (Star of David; Fig. 1). Cell division of the nearly symmetrical organisms begins with a slight elongation in two directions. The cross-wall separates the daughter cells, whose shape is that of two three-pronged crowns. The nearly triangular appendages (prosthe-cae) are also flat, and so the Stella cell has, if seen from the side, a lens shape.
