Serum samples were stored in al" at -80C prior to analysis Faecal samples were collected, stored at -80. To determine spontaneous release, 100 l rpmi/5 FCS without effector cells are added. Niemand muss seinen Namen preisgeben, sich irgendwo eintragen oder etwas ausfüllen. The compositions disclosed herein may be formulated in a neutral or salt form. Said nutraceuticals or pharmaceutical compositions and preferred embodiments thereof are described in detail elsewhere herein. 3 x 105 cells per tube were pelleted and the pellet was resuspended in 50l murine serum (diluted 1:300 in PBS/1BSA control antibody or PBS/1BSA alone.

Selected Core-1 positive strains as well as strains that were not Core-1 positive were characterized by their sensitivity against different antibiotics (see table 1FIG. Both rough CPS extracts were prepared from different cultures. The carbohydrate epitope positive cells are labeled with europium or chromium-51 which allows the measurement of cells which are lysed. 3 2 The accumulation of fucose, GalNH2 / GalNAc and galactose might be an indication, that these monosaccharides are components of the repeating units of the core-1-positive polysaccharide. Bringing into contact a suitable amount of dendritic cells comprising at least one dendritic cell, dendritic cells, or a mixture of cells comprising at least one dendritic cell, loaded with a suitable amount of the carbohydrate positive microorganism, a lysate or a fraction thereof, formulations.
