Black arrows indicated the chloroplast of A. sanguinea.(B) Uninfected A. sanguinea showing nucleus, nucleolus (red circle) and nucleus membrane.(C) 12 h infection with multiple parasite (red arrow) in host nucleus.(D) 30 h infection showing nascent mastigocoel (M) and multilobed cavity (L).(E) 54 h infection showing “beehive” with fully developed mastigocoel (M) and multilobed cavity (L).(F) Transverse section through 54 h Amoebophrya sp. trophont within the A. sanguinea nucleus. The host cytoplasm (H) was relegated by the parasite to the margin of the cell. The mastigocoel (M) contains numerous flagella (F), and the nucleus (N) line up in a continuous fashion along the folds of the “beehive.” Asterisk indicated the clusters of parasite trichocysts.(G) Detail of chloroplasts in the 54 h infected A. sanguinea.
