[Possible interactions between Toxoplasma gondii infection and the presence of non-Hodgkin's lymphoma]

The presence of antibodies to Toxoplasma gondii was studied in the sera of 63 patients with non-Hodgkin lymphoma. After the age of 30 years, antibodies to the parasite increase progressively in the whole population, but the incidence and titer are significantly higher in non-Hodgkin lymphoma patients. After the chemotherapy treatment, the titer of the antibodies to Toxoplasma gondii augment-ed.
