Subpopulation composition of peripheral blood lymphocytes in children with infectious mononucleosis.

In patients with viral and bacterial infectious mononucleosis during the acute period of disease and clinical convalescence blood content of CD72(+)and CD16(+)lymphocytes increased compared to normal. The count of CD8(+)cells increased in viral mononucleosis during convalescence and these changes persist in delayed periods after convalescence. In bacterial mononucleosis the content of CD72(+)lymphocytes return normal 18 months after convalescence.
