[Animal study on radioactive antigenic fractions isolated from V.cholerae. I. The Ch 1 + 2 fraction].
The Ch 1 + 2 fraction has been marked by means of culture of Vibrio cholerae Ogawa HK1 on a synthetic medium containing leucine H3. The antigen distribution has been then studied before and after vaccination with the same non-marked antigen in normal and axenic mice, at the same time by the demonstration of radioactivity and radioimmunofluorescence in intestine, spleen, liver, kidney and thymus. Whichever the administration route, intestine and spleen are first stimulated, then more intensively with the second injection or ingestion. When administrated per os the fraction crosses the intestinal barrier and is fixed on the main lymphoid organs: intestine, spleen, thymus. After ingestion or injection into axenic mice, spleen is the first organ stimulated.
