Fine structure of Theileria parva in the Bovine skin
Abstract
Ultrastructural studies of Theileria parua in the bovine skin revealed 'infective particles'
of the parasite. These parasite forms were pleomorphic and were found extracellular or
within host lymphoid cells, neutrophils and erythrocytes. The parasites were Bproduct of
extracellular schizogony. They were phagocytosed by the host leucocytes but seemed
actively to invade the erythrocytes. Several extracellular uninucleate schizonts were also
observed. The presence of extracellular infective particles, uninucleate schizonts and
multinucleate schizonts, some showing schizogony, suggests an extracellular life cycle of
T. parua within bovine tissue.
