RESUMO
The study is concerned with the effect of repeated administration of staphylococcal immunopreparations on the development of a suppurative-inflammatory focus in the foot of the mouse. Subcutaneous administration of large doses of the antigenic complex of the staphylococcus (ACS) obtained by aqueous extraction, antiphagin and native anatoxin failed to induce an increase in sensitivity to staphylococcus. In some cases, the extent of development of the suppurative-inflammatory focus in the mice which had been given these preparations was less than in the control; this is suggestive of their protective effect. When comparing, on this model, the ACS preparations and corpuscular vaccine produced from poorly and highly virulent strains, we observed a more pronounced protective effect in the preparations from the poorly virulents strains. The extent of oedema was greater than in the control when adsorbed anatoxin was administered. The administration of staphylococcal preparations with a therapeutical purpose after staphylococcus infection caused a significant decrease in the size and intensity of manifestation of the suppurative-inflammatory focus in the foot. The model of limb oedema enabled us to reveal the sensitizing and protective effect of the preparations under study.
