[The spread of antibodies to cytomegalovirus and Toxoplasma among donors of blood components].

The spread of IgG antibodies to cytomegalovirus and Toxoplasma in the blood sera of 323 donors of hemocomponents was studied. Among young males in the northwestern region of Russia three fourths were found to be seropositive to cytomegalovirus and one third, to Toxoplasma. In older ages the proportion of seropositive persons somewhat increased. In donors with blood group O (I) antibodies to cytomegalovirus occurred almost twice as often (91%) as in donors with blood group AB (IV) (47%). Among donors with blood group AB (IV) the proportion of persons seropositive to Toxoplasma (54%) was twice as great as that among donors with blood group O (I) (27%).
