Abstract

It has been estimated that 60 percent of people in Croatia will be infected with Toxoplasma gondii until the age of 40. The infection is most frequently asymptomatic, or presented with an lymphadenitis, acute infection during pregnancy that can cause serious damage to the fetus in 10-30 percent, depending on the gestation phase. After acute infection Toxoplasma gondii resides in the body for life, being controlled by cellular immunity. In case of the immune system compromise, reactivation of the infection and serious inflammatory changes, mostly in the central nervous system, occur. Prenatal infection and serious clinical picture in immunocompromised patients classify toxoplasmosis among ever topical infections, thus all research toward better understanding of its pathogenesis in immunocompetent patients is of utmost importance. The aim of the study was to systematically analyze the morphology and changes in cytologic smears of lymph nodes from patients acutely infected with Toxoplasma gondii, and to morphologically visualize Toxoplasma gondii in the lymph nodes by use of specific monoclonal antibodies. For this purpose, 30 aspirates of lymph nodes of patients who had definite serologic evidence for and clinical picture of acute toxoplasma infection were analyzed by use of classic cytology and immunocytochemistry methods. Results confirmed a recognizable cytologic picture of reactive hyperplasia of follicular center cells and granulomatous inflammation, with a unique finding of Toxoplasma gondii tachyzoite in lymphatic cells.
