[Effect of a polysaccharide-contaning preparation from El Tor vibrions on the phagocytic activity of leukocytes and on the lysozyme titer].

The dynamics of changes in some indices of the natural immunity of mice treated with EL-Tor vibrio preparations in doses of 50 and 500 gemma/mouse was studied. The blood for analysis was taken from the mice 24 hours, 3, 7 and 10 days after the preparation administration. The results of the study showed that administration of the polysaccharide-containing preparations from El-Tor vibrios in doses of 50 and 500 gemma/mouse was accompanied by some shifts in the regulatory mechanisms: suppression of the serum lysozyme activity on the 1st and 3rd days and its stimulation on the 7th and 10th days.
