. The cellular response, within the kidney of experimentally infected carp to the presence of eggs of the blood fluke Sanguinicola inermis has been investigated using transmission electron microscopy. Initially, 0–1‐wcck‐old eggs were surrounded by host eosinophils which degranulated and broke down adjaeent to the egg shell. Infiltration by neutrophils and monocytes occurred around 1–2‐week‐old eggs. Eggs at 2–3 weeks of age began to become encapsulated, although the first signs of structural damage appeared when the eggs were 5–6 weeks of age.
