Sphere--Rod Morphogenesis of Escherichia Coli

Morphogenesis of Escherichia coli.

The shape of Escherichia coli is strikingly simple compared to those of higher eukaryotes. In fact, the end result of E. coli morphogenesis is a cylindrical tube with hemispherical caps. It is argued that physical principles affect biological forms. In this view, genes code for products that contribute to the production of suitable structures for physical factors to act upon. After introduction...

Solvation Force in Hard Ellipsoid Molecular Liquids with Rod-Sphere and Rod- Surface Interactions

In previous work, one of us calculated the Solvation force of hard ellipsoid fluid with hard Gaussian overlap potential using hard needle wall interaction and non-linear equation proposed by Grimson- Rickyazen. In present work, using density functional theory and extended restricted orientation model, the solvation force of hard ellipsoid fluid in presence of more realistic rod- sphere and rod-...

Cell length, nucleoid separation, and cell division of rod-shaped and spherical cells of Escherichia coli.

By comparing the dimensions and DNA contents of normal rod-shaped Escherichia coli with those of mutants that grow as spheres or ellipsoids, we have determined that two parameters remain unchanged: the DNA/mass ratio and the average cell length (diameter, for spherical cells). In consequence, the average volumes and DNA contents of the spherical mutant cells are about four to six times greater ...

Production of MAG1 Antigen of Toxoplasma gondii in Escherichia coli

  Introduction : Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii it leads to serious medical problems in congenitally-infected and immunocompromised individuals, while it is quite harmless in immunocompetent individuals. Toxoplasma tissue cyst matrix protein (MAG1) induces early humoral and cell-mediated immune responses. Previous studies suggested recombinant M...
