组织学的部分Biomphalaria glabrata感染了1000 L1答:vasorum。苏木精和伊红染色。(一)肉芽肿的形成两个不同的层,内部类上皮细胞方面(黑色星号)和外,与纤维母细胞等细胞(箭头所指)。白色的十字架显示细胞的形成按钮的一侧开始感染的幼虫后六天;(b)的幼虫(箭头)蛋白腺内被细胞反应;白色的星号显示细胞反应开始后6天感染;(c)内肉芽肿形成肾动脉(白色星号)的感染后14天开始。肾空间是由黑色的星号,箭头所指示的幼虫是L2因为这颗粒在肠(14天);(d)肉芽肿足背地区确定变薄的上皮(箭头所指)感染后14天开始;(e)幼虫在脚的肌纤维组织强烈反应以按钮的形式(黑色星号)没有典型的肉芽肿,20天后开始的感染; (f) larva (white arrow) in a less typical granuloma located in the conjunctive tissue around the kidney (black asterisk) thirty days after the beginning of infection. (g) Weak cellular reaction around the larva with looser appearance. It can be observed larvae within mucus cells (black asterisk) thirty days from the beginning of infection; (h) larvae located in foot fibromuscular tissue without presenting typical granulomatous response, keeping the space even more clear after thirty days at the beginning of infection.
