Plasma levels of phospholipids, triglycerides, high density lipoproteins (HDL)-cholesterol and HDL-phospholipids were studied in 48 11-d-old female mule ducks infected per os with 5 x 10(3) x 10(4) x 5 x 10(5) sporulated oocysts of Eimeria mulardi (D0), or kept as an uninfected control group. Data were recorded from D-1 to D17. Mortality and weight loss were only observed with the 5 x 10(5) oocyst dose. Plasma phospholipids were significantly reduced with the two highest infecting doses on D3, and returned to normal values by D9 with the highest infecting dose. The minimum level attained was no lower than 74% of the control group. Triglyceride levels were reduced early but only slightly and irregularly in the three infected groups. HDL-cholesterol was significantly reduced from D5 and HDL-phospholipids from D3. These reduced levels depended on the infecting dose and were lowest on D5, respectively 34 and 35% of the control group with the highest infecting dose. In this group, the levels remained lower than in the uninfected group on D17. These perturbations in blood lipid classes have been described in avian coccidiosis.
对48只11日龄雌性骡鸭进行了研究，这些骡鸭经口感染5×10³、4×10⁴或5×10⁵个已孢子化的穆拉艾美耳球虫卵囊（第0天），或作为未感染的对照组。从第-1天到第17天记录数据。仅在感染5×10⁵个卵囊剂量时观察到死亡率和体重减轻。在感染后第3天，血浆磷脂在两个最高感染剂量组显著降低，在最高感染剂量组中到第9天恢复到正常水平。达到的最低水平不低于对照组的74%。甘油三酯水平在早期降低，但在三个感染组中仅轻微且不规则地降低。高密度脂蛋白胆固醇从第5天起显著降低，高密度脂蛋白磷脂从第3天起显著降低。这些降低的水平取决于感染剂量，在第5天最低，在最高感染剂量组中分别为对照组的34%和35%。在该组中，第17天的水平仍低于未感染组。禽球虫病中已描述了这些血脂类别的扰动情况。
