[The presence of the Epstein-Barr virus in Waldeyer's lymphatic ring during the acute phase of infectious mononucleosis].

The aim of our research was to detect the existence of virus Epstein-Barr genome in the palatine- and the nasopharyngeal tonsil obtained from six patients during the acute phase of the infectious mononucleosis. The presence of EBV-DNA was demonstrated with the help of nucleic acid hybridization techniques (Southern-Blot and in situ hybridization) in the two components of the lymphoepithelial ring of the throat. The pathogenesis and the therapeutic implications of these findings are discussed.
