[The ultrastructure of the intraerythrocytic stages of Babesia herpailuri-trophozoites and merozoites after treatment with imidocarb (3,3'-bis-2-imidazolin-2-yl)-carbanilide (author's transl)].

The fine structure of trophozoites and especially of merozoites of Babesia herpailuri is described before and after treatment with Imidocarb (Wellcome). The mostly piriform to oval merozoites possess an outer membrane and a supporting membrane below. The intratorium consists of a polar ring, rhoptries micronemes and the sperical body which lies beside the big nucleus and next to mitochondria.
