Cell wall composition in the classification of Vibrio fetus

Cell walls of most Biotype 1 strains of V. fetus contained galactose and mannose; one type 1 strain had galactose and glucose. Cell walls of most Biotype 2 strains also had galactose and mannose; how-eger, some strains had galactose, glucose and mannose, some galactose alone and some galactose and rhamnose. Cell walls of most Biotype 3 strains had galactose and glucose; a few had galactose, glucose and mannose, or galactose alone. Whole cells of V. fetus contained small amounts of mesodiammopimelic acid (DAP), but meso-DAP could not be detected in purified cell walls.
