Proteus Flagella Stain

Flagella are too thin to be seen with a light microscope without enhancement. Liefson’s flagella stain can be used to demonstrate their presence. During the procedure, the stain becomes deposited upon the flagella until they are thick enough to be seen.  Note the numerous thread-like flagella extending from the cells. What type of flagellation do these cells possess?
