Lead nitrate was used as capture agent for phosphate liberated during the hydrolysis of the substrate (cytidine 5' monophosphate). Lead phosphate precipitation, indicative of enzyme activity, was located in membrane-bound organelles corresponding to the cytoplasmic inclusions known as 'dense bodies'. Acid phosphatase activity level and sodium L-tartrate inhibition were measured spectrophotometrically from a purified parasite suspension. The possible involvement of this enzyme in intracellular survival of B. ostreae is discussed.
