Spiroplasma melliferum is a wall-less bacterium with dynamic helical geometry. This organism is geometrically well defined and internally well ordered, and has an exceedingly small genome. Individual cells are chemotactic, polar, and swim actively. T

Salmonella typhimurium SJW23 has a right-handed, non-helically perturbed filament of serotype gt with a unique surface pattern. Non-helical perturbations involve symmetry reduction along the five-start helical lines resulting in layer lines of fracti

Spiroplasmas belong to the class Mollicutes, representing the minimal, free-living, and self-replicating forms of life. Spiroplasmas are helical wall-less bacteria and the only ones known to swim by means of a linear motor (rather than the near-unive

Spiroplasma melliferum is a wall-less bacterium with dynamic helical symmetry. Taking advantage of the simplicity of this primitive lifeform, we have used structural (electron tomography and freeze fracture of whole cells; cryoelectron tomography and

Archaea, constituting a third domain of life between Eubacteria and Eukarya, characteristically inhabit extreme environments. They swim by rotating flagellar filaments that are phenomenologically and functionally similar to those of eubacteria. Howev

Spiroplasma are wall-less, helical bacteria from the class Mollicutes. The Mollicutes (Mycoplasma, Acholeplasma, Spiroplasma) evolved by regressive evolution to generate one of the simplest and minimal free-living and self-replicating forms of life.

A pure-streamfunction formulation is introduced for the numerical simulation of the two-dimensional incompressible Navier-Stokes equations. The idea is to replace the vorticity in the vorticity-streamfunction evolution equation by the Laplacian of th

The Mollicutes (Spiroplasma, Mycoplasma and Acholeplasma) are the most minimal cells known to exist, being the smallest and simplest free-living and self-replicating forms of life. Phylogenetically, the Mollicutes are related to gram-positive bacteri

Of the two known “complex” flagellar filaments, those of Pseudomonas are far more flexible than those of Rhizobium. Their diameter is larger and their outer three-start ridges and grooves are more prominent. Although the symmetry of both complex

Summary Bacterial flagella, the organelles of motility, are commonly divided into two classes: ‘plain’ and ‘complex’. The complex filaments are pairwise, helically perturbed forms of the plain filaments and have been reported to occur only in
