Spiral conformation of Vibrio cholerae as determined by scanning electron microscopy of elongated cells induced by cephalexin treatment

Abstract
The elongated cells of Vibrio spp. induced by cephalexin treatment were examined by scanning electron microscopy. The results showed that Vibrio cholerae has a twisted cell body and a right-handed spiral conformation and that the cell bodies of V. parahaemolyticus and V. alginolyticus are straight rather than curved.
