The pathogenesis of reduced egg production with soft-shelled eggs in laying hens naturally infected with Leucocytozoon caulleryi was investigated. Many large schizonts of L. caulleryi schizonts were seen in the ovary and oviducts of chickens. Granulomatous and lymphocytic inflammation, edema, and pressure atrophy were associated with these schizonts. The uterine region that secretes the egg shell exhibited the most severe damage. These lesions in the reproductive organs may explain the mechanism for causing the reduced egg production and soft-shelled eggs in laying hens infected with L. caulleryi.
对自然感染卡氏住白细胞虫的蛋鸡产蛋量下降及产软壳蛋的发病机制进行了研究。在鸡的卵巢和输卵管中可见到许多卡氏住白细胞虫的大裂殖体。肉芽肿性和淋巴细胞性炎症、水肿及压迫性萎缩与这些裂殖体有关。分泌蛋壳的子宫区域损伤最为严重。生殖器官的这些病变可能解释了感染卡氏住白细胞虫的蛋鸡产蛋量下降和产软壳蛋的机制。
