Large-scale surveys of representative population groups (n = 2243) in 7 cities and 3 provinces of the central, Povolzh'e, and northwestern regions of the Russian Federation provided the basic epidemiological features of cryptosporidiosis in the European part of the country. Its mean incidence of the population was 3.34%, much higher in children (3.

Two groups of children were under survey.

The leishmania infection caused by immunosuppression is successfully eliminated by the animal organism soon after the stopping of immunosuppressant action, that could be considered as the restitution of the natural resistance.

The first group included 165 persons living in Vyshkov (settlement of town type in Bryansk Region) contaminated with radionuclides as a result of Chernobyl accident. The second group included 68 persons living in Vyshkov, immunological monitoring of those was performed.

In the series of experiments with the mercy scheme of immunosuppression the inoculation of the amastigotes L. infantum taken out of the donors, the golden hamsters Mesocricetus auratus, caused the progressive infection with intensive affection on target organs (the spleen, liver, bone marrow).

On the background of the immunosuppression caused by corticosteroids of short time activity (metipred, hydrocortison) leishmaniae were revealed both in the target organs (spleen, liver, marrow) and in lungs, in cases of using the corticosteroid of prolonged activity (tricort-40) leishmaniae were observed also in lungs, kidneys, testis.

The series of experiments has shown that the immunosuppressor Tricort-40 (corticosteroid of prolonged activity) in a short time reactivates the Pneumocystis infection. The parasites have been observed in a great number in the lungs and rarely in the liver.

August 1994
A total of 248 adults (170 with somatic diseases and 78 with the diarrheal syndrome) and 1206 children (323 attending kindergartens, 231 with somatic diseases, and 652 with the diarrheal syndrome), residents of seven towns of Russia and Belarus, were examined for cryptosporidiosis in 1989-1992. The mean infection rate of children and adults with the diarrheal syndrome was 4.8 and 2.
