Examination of the Ultrastructure of Two Phenotypically Different Clones of <I>V. cholerae</I> by Means of Transmission and Scanning Electron Microscopy

Abstract

Submitted are the data of examination of the ultrastructure of two phenotypically different clones (toxigenic and non-toxigenic) of V. cholerae Dakka35 strain by means of electron microscopy. Additional layer (capsule) of polysaccharide nature is identified on the surface of non-toxigenic clone bacteria. This layer (absent in toxigenic clone) alters colony morphology.
