Fig. 4From: Mortality and pathology in birds due to Plasmodium (Giovannolaia) homocircumflexum infection, with emphasis on the exoerythrocytic development of avian malaria parasitesPhanerozoites of Plasmodium (Giovannolaia) homocircumflexum (cytochrome b lineage pCOLL4) in histological sections of the same organs stained with haematoxylin-eosin (a–c, g–i) and processed with chromogenic in situ hybridization (d–f, j–l): brain (a–f) and heart (g–l) of common crossbill Loxia curvirostra. Images of same preparations are given at low (×200; a, d, g, j), medium (×400; b, e, h, k) and high (×1000; c, f, i, l) magnifications. Short arrows: phanerozoites; long arrows: merozoites; Scale bars 25 μmBack to article page
