The duration of immunity to heartwater normally varies from 6 months to 4 years. In Angora goats it may be difficult to produce a specific immune response with vaccination. Humoral immunity does not appear to play a role in the development of immunity. It has been suggested that cellular immunity may play a role, but the actual mechanism involved remains obscure. The specific immune response developing in farm animals following infection with Cowdria ruminantium is reviewed.
对心水病的免疫持续时间通常在6个月至4年之间。对于安哥拉山羊，通过接种疫苗产生特异性免疫反应可能很困难。体液免疫似乎在免疫发展过程中不起作用。有人提出细胞免疫可能起作用，但其中涉及的实际机制仍不清楚。本文综述了反刍动物感染反刍兽考德里氏体后家畜中产生的特异性免疫反应。
