[Sensitization of lymphocytes from newborn infants and young children to pathogenic and opportunistic microflora]

The nucleolar test was used to study sensitization of peripheral blood lymphocytes from the newborn and infants. The test is based on the counting of cells with a clarification area around nucleoli after incubation with antigens and microbial bodies of the pathogenic and opportunistic microflora. It has been established that the peripheral blood from children with infectious-inflammatory diseases and from those vaccinated with BCG shows an increase in the sensitized lymphocyte count which is influenced by child's trophicity at birth and by administration of antibacterial therapy. The use of the nucleolar test as a diagnostic aid is advisable to identify the disease etiology.
