spherical body organelle and not microneme and not nucleus during early cell division and early extracellular merozoite and trophozoite, erythrocyte cytoplasm during intracellular merozoite
  • "The immunoelectron microscopic examination confirmed the localization of BbSBP-4 in spherical bodies, but not in the nucleus, rhoptries, and micronemes. Interestingly, the protein was found to be localized not only in the spherical body of Babesia bovis but also in the cytoplasm of infected erythrocytes (iRBC) at the later stage of parasite development."
