ABSTRACT
985 wild small mammals and birds were serologically investigated for toxoplasmosis from 1981 to 1984 in Turkmenia: antibodies to Toxoplasma gondii in the indirect hemagglutination and immunofluorescent complement fixation reactions according to Goldwasser and Shepard were found in 247 (25.0%), in 11 of 17 investigated species of mammals and in 13 of 22 species of birds. A sharp rise in the toxoplasmosis infection level of wild mammals was found out serologically for the first time (from 1.2% in autumn, 1982 to 72.6% in spring, 1983) followed by its reduction against the reduction in the number of animals. This must have taken place as a result of heavy toxoplasmosis epizootics in the region of investigations which is frequented by wild and domestic cats.

Information on the serologic and parasitologic prevalence of Toxoplasma gondii infection in domestic and wild animals of the U.S.S.R. is reviewed. Although complement-fixing antibodies to T. gondii were widely prevalent in animals, little information is available on the presence of viable T. gondii in tissues of animals. Reports of epizootics in which T. gondii was suspected to be the causative agent of toxoplasmosis are summarized. Also, the strict economic impact of toxoplasmosis on agriculture in the U.S.S.R. needs evaluation.

Antibodies to Toxoplasma in the reaction of indirect hemagglutination were found in 8 species of mammals and 2 species of birds. Carriage of antibodies to Toxoplasma in house mouse, common fox, bald coot , and rock-dove was first recorded from Turkmenia . Analysis of the infection with Toxoplasma according to species, habitat of antibodies carriers, their ecology, age, sex and season of investigation is given.

In oral infection with cysts and oocysts of strain 131 Toxoplasma gondii, specific interstitial productive myocarditis with involvement of the endo- and pericardium developed in albino mice and guinea pigs in the acute stage of the process. Toxoplasmic myocarditis terminated in focal cardiosclerosis. The intensity of cardiac affection was higher in oral infection with toxoplasm oocysts than in infection with cysts than in infection with cysts. Unabating persistence of toxoplasms in the myocardium of the infected animals after subsidence of acute inflammatory phenomena was revealed (cysts in the myocardium).
