[Parasitic carriage of the causative agents of tropical malaria].
In 1993 to 1999, a total of 1020 Russians temporarily living in the Republic of Guinea were examined; of them 26 (2.5%) persons were found to be asymptomatic carriers of P. falciparum. Single studies of cellular and humoral immunity were first conducted in 15 asymptomatic parasitic carriers of P. falciparum. Asymptomatic parasitic carriage of P. falciparum was established in nonimmune persons who developed immunopathological reactions. The nature of immune disorders gives grounds to regard parasitic carriage as a subclinical form of tropical malaria for the first time. By taking into account asymptomatic carriage of P. falciparum, a parasitological blood study should be made in all non-immune persons when they are leaving an endemic focus for Russia.
