Fig. 2. Tissue stages of Leucocytozoon parasites in naturally infected song thrushes Turdus philomelos, found in hematoxylin-eosin (H&E) stained (a, b, e, f) and chromogenic in situ hybridization (CISH) treated (insert in b, and c, d) histological sections. Early meronts in the kidneys of individual no. 1 (cytochrome b lineage lTUPHI14) (a), and advanced meronts in the kidneys of individual no. 2 (lSTUR1) (b) and no. 5 (co-infection of lSTUR1 and lTUPHI13) (e, f). Meronts labelled by a Leucocytozoon-specific (Leuco18S) probe in the kidneys (insert b), and lungs of individual no. 2 (lSTUR1) (c) and individual no. 3 (lSTUR1) (d). Tissue stage developing in the Bowman capsule of a renal corpuscle (e). Leucocytozoon blood stage labelled by a Leucocytozoon-specific probe (c). Simple black arrowheads: meronts. Simple white arrowheads: cytomeres (visible as darker stained nuclei surrounded by lighter staining clefts). Short simple black arrow: nucleus of Leucocytozoon blood stage. Scale bars 20 μm.
