GENERAL FEATURES 

 MOTILITY AND ITS MECHANISM 



The relation of flagella to motility in bacteria has been well established, and the

 for structures in spirochetes analogous to bacterial flagella led to the demonstration 

 in some forms of delicate terminal filaments which were at first interpreted as hav-
