RESUMO
The data on the fauna of trypanosomes of Anura of the Leningrad Province are given. The initial development stages of Trypanosoma rotatorium in peripheral blood and internal organs of the frog are described for the first time.

Eggs of three Bufo species (B. bufo, B. viridis and B. calamita) were examined for blood group activity. B. bufo showed distinct A activity, whereas in B. viridis and B. calamita a marked H-activity was observed. These results correspond with the zoological systematic classification of the three toad species tested.

The ultrastructure of leukocytes of the peripheral blood was studied in representatives of classes of fishes (Cyprinus carpio), amphibia (Rana redibunda, Bufo bufo), reptiles (Testudo horshfield), birds (Columba livia) and mammals (Rattus norvegicus). The granules are characterized by homogeneous or heterogeneous matrix. The granules of special leukocytes (turtle) and pseudoesinophils (pigeon) have larger dimensions than those in neutrophils of other animals. The matrix of the eosinophil granules of the carp and rat contain crystalloid structures while the granules of eosinophils of amphibia, turtles and pigeons are characterized by electron dense homogeneous matrix. The basophil granules are larger and in addition to homogeneous or fine granular structure (turtle, pigeon, rat) have lamellar structure (Cyprinus carpio, frog, toad). The ultrastructural organization of agranulocytes and plasma cells of the animals studied is also described.
