The lipid bilayer is a thin polar membrane made of two layers of lipid molecules.These membranes are flat sheets that form a continuous barrier around all cells.The cell membranes of almost all living organisms and many viruses are made of a lipid bilayer, as are the membranes surrounding the cell nucleus and other sub-cellular structures.rokaryotes have only one lipid bilayer-the cell membrane (also known as the plasma membrane). Many prokaryotes also have a cell wall, but the cell wall is composed of proteins or long chain carbohydrates, not lipids.
Before the discovery of an infectious cause, the symptoms of cholera were thought to be caused by an excess of bile in the patient; the disease cholera gets its name from the Greek word choler meaning bile.This theory was consistent with humorism, and led to such medical practices as bloodletting.ack of animal models: Experimental infection in animals has been used as a criterion to demonstrate a disease-causing ability, but for some pathogens (such as Vibrio cholerae, which cause disease only in humans) animal models do not exist.
