From: Patterns of Plasmodium homocircumflexum virulence in experimentally infected passerine birds
Phanerozoites of Plasmodium (Giovannolaia) homocircumflexum (cytochrome b lineage pCOLL4) in histological sections of brain (a, b), lung (c, d), liver (e, f), spleen (g, h), kidney (i, j), heart (k, l) and pectoral muscle (m, n) of experimentally infected Passer domesticus (a, c, e, g, i, k, m) and Fringilla coelebs (b, d, f, h, j, l, n). Morphologically similar phanerozoites were reported in all infected experimental birds, but they were absent in starlings. Short arrows: phanerozoites, long arrows: merozoites. Haematoxylin–eosin stained preparations. Scale bar = 20 μm
