Hearts from 2-to-3-week-old broiler chicks that were inoculated with 2 X 10(6) sporulated oocysts/bird weighed significantly less than hearts from control chicks at 4 and 7 days postinoculation (PI). However, heart weights of infected chicks expressed as percentage of body weights were not significantly different from those of controls throughout the experiment. Infection also had no significant effect on heart protein content. Cardiac glycogen was significantly increased at 7 days PI but not at 4 days PI. Oxidation of both alpha-ketoglutaric and octanoic acids by mitochondrial preparations from hearts of infected chicks was significantly depressed at 4 days PI compared with controls; at 7 days PI, however, oxidation of octanoic acid was significantly increased, but that of alpha-ketoglutaric acid was not.
接种2×10⁶个孢子化卵囊/只的2至3周龄肉鸡雏鸡的心脏，在接种后4天和7天的重量显著低于对照雏鸡的心脏。然而，在整个实验过程中，感染雏鸡的心脏重量以体重百分比表示与对照组并无显著差异。感染对心脏蛋白质含量也没有显著影响。心肌糖原在接种后7天显著增加，但在接种后4天没有增加。与对照组相比，感染雏鸡心脏线粒体提取物对α-酮戊二酸和辛酸的氧化在接种后4天显著降低；然而，在接种后7天，辛酸的氧化显著增加，但α-酮戊二酸的氧化没有增加。
