“…This is inconsistent with Clark et al (2004) who stated that one to two B. thylacis in an infected erythrocyte caused no such changes to erythrocytes in an unspecified Australian mammal. In our study, the transmission microscope images revealed some structures that are similar to those described for other Babesia spp., such as B. bovis and B. microti ( Rudzinska, 1976; Todorovic et al, 1981 ). The number of infected erythrocytes in the capillaries in the kidney was much higher than that examined by the blood smears.…”

“…This may be ascribed to the high magnification of the electron microscope which identifies the remains of autolysed Babesia and erythrocytes. In B. bovis , no food vacuole or host cytoplasm was found ( Todorovic et al, 1981 ). However, in the Babesia sp.…”

“…The presence of Maurer's clefts has been reported in B. bovis trophozoites, especially in multiple infections of a single bovine erythrocyte (Todorovic et al 1981). This structure has also been recognized in trophozoites of B. bigemina, B. divergens, B. microti, and some Plasmodium species (Saal 1964 ;Rudzinska 1981;Atkinson and Aikawa 1990).…”

In-vitro-propagated Babesia caballi parasites were examined by scanning and transmission electron microscopy. Many small pores were observed over the entire surface of infected erythrocytes on scanning electron microscopy, and on transmission electron microscopy these small pores were found to be openings of tubular structures. By the examination of a number of infected cells the tubular structures were found to be connected with the parasite, and this observation might indicate that the tubular structures arose the edge of the parasite and terminated at an Invagination on the surface of the erythrocyte. These findings suggest that intraerythrocytic stages of B. caballi come into direct contact with culture medium.

“…Friedho and Scholtyseck (1977) reported that a large spherical body, not seen in other members of the subphylum Apicomplexa, occurs in merozoites of certain Babesia species. This organelle has been observed in merozoites of B. bigemina, B. ovis, B. bovis and B. ovata (Friedho and Scholtyseck 1977;Els 1977, 1979;Todorovic et al 1981;Kawai et al 1986). Therefore, the digested food vacuole observed in an erythrocytic merozoite of B. caballi should be a spherical body, as reported by Friedho and Scholtyaseck (1977) and other authors.…”

As far as we could determine, the piriform merozoites of B. caballi were composed of an outer membrane and an inner membrane complex consisting of a double membrane.…”

Babesia caballi cultured continuously in equine erythrocytes was examined by transmission electron microscopy. The use of cultured B. caballi permitted examination of a large number of parasitized cells with various stages of intra erythrocytic development. The piriform merozoites of B. caballi were composed of an outer membrane and an inner double-membrane complex. Numerous micronemes and three rhoptries were found in the pellicle of the merozoite, and a spherical body was seen in the anterior part of the merozoite which usually lay adjacent to the nucleus and the pellicle. These findings were similar to those for merozoites of bovine Babesia parasites such as B. bigemina. The trophozoites were surrounded by a single membrane, were continuously changing their body shape with extension and retraction of the pseudopod. A long pseudopod extended far into the host cell cytoplasm, and was finally completely enclosed in a cell, but did not have hemozoin pigment, the breakdown product of hemoglobin digestion.
