Images of infected hearts using the micro-CT technology, showing the location and the appearance of the plasmodia in the ventricle. a 3D volume rendering of the heart #1. Two plasmodia (p1, p2) of Henneguya aegea n. sp. are visible through a dissection cut in the ventricle. Red lines indicate the section plan of the corresponding 2D cross-section images (b and c). d Cross-section image of the heart #2 showing two large plasmodia in the ventricle (p2 and p3) and one in the junction of the bulbus arteriosus with the ventricle. e Heart #2 (scanned in D) dissected in the area where the plasmodia were identified through micro-CT showing the actual location and appearance of p2 and p3. Abbreviations: a, atrium; b, bulbus arteriosus; p, plasmodium; v, ventricle
