Immunolocalization of T gondii associated to host cells in the brain. (A) Single tachyzoite (anti-SAG1, red) associated with a CD11b⁺ cell (green) at 7 days after inoculation. (B) Bradyzoites (anti-P36, red) multiplying within a CD11b⁺ cell (green) at 9 days after inoculation. (C) Tachyzoites and (D) bradyzoites dividing within a CD11c^- -CD11b^- cell at day 9 after inoculation. Nuclei were stained with DAPI (blue). Scale bar = 2 μm. Images were visualized with a 63×/1.25 Plan-neofluar objective lens (Zeiss).
