[1st stage of infectious allergy].
In administration of bacterial exotoxins (diphtheria, botulinic) to guinea pigs in doses of 1/100 Dlm at an interval of one hour there developed a typical sickness with the lethal outcome in the course of 2-3 days from the beginning of the exotoxin administration. Low bacterial exotoxin doses induced allergic reaction of the organism before the cell producing specific antibodies began to act in defence. Lymphatic system cells responded rapidly to the low doses of bacterial exotoxins, but the process of formation of cells producing antibodies failed to reach mature plasmocytes, and no antibodies formed. With increase of the interval between the administration of low bacterial exotoxin doses to 24 hours specific antibodies did form, but these antibodies failed to protect the animals which were in the state of infectious allergy. The first stage of infectious allergy induced by low bacterial doses was nonspecific. Animals which were in the state of infectious allergy to diphtheria exotoxin perished of low botulinic (exotoxin) doses, and vice versa.
