[The ontogeny of the cell receptors of the adhesion of meningococci and influenza viruses].

Specific age and individual features of the adhesion of Neisseria meningitidis, groups A, B and C, and influenza viruses, types A and B, to red blood cells of humans aged 0-60 years were studied. The study revealed that the red blood cells of newborns, in contrast to those of persons of older age groups, are highly resistant to N. meningitidis adhesion, but highly sensitive to the adhesion of influenza viruses, though to a varying degree. The postnatal period of ontogenesis is characterized first by a sharp rise (up to 1 month) and then by a slower increase of the individual sensitivity of red blood cells to N.meningitidis adhesion without essential changes in the sensitivity of the same cells to the adhesion of influenza viruses.
