title: [Study of Vibrio cholerae fractions. II. A comparison of the immunochemical and biological properties of preparations of alkaline extracts (vibrionin) and the endotoxin of Vibrio cholerae].
abstract: Comparative study of immuno-chemical and biological properties of vibrionin and cholera vibrio endotoxin showed vibrionin to contain up to 73.5% of protein, whereas endotoxin preparations contained only 25% of protein. Use of disc electrophoresis in polyacrylamide gel permitted to determine the relative electrophoretic mobility of the protein component bands of both preparations. Residual quantities of O-antigenic cholera vibrio determinants were revealed serologically in the vibrionin preparations. Study of biological properties of vibrionin (cholera allergen) demonstrated a possibility of using vibrionin in the capacity of a new bacterial allergen.
