Ultrastructural changes in the hepatopancreas of B. aeruginosa exposed to the suspension of M. aeruginosa and mixed algae, respectively. (a) Nucleus of control snail, 12000x. (b) and (c) The deformation and fading of nucleus in the mixed group at 5 days and 15 days postexposure, respectively, 30000x and 20000x. (d) The binucleate cell (yellow arrow), 12000x. (e) The condensation of chromatin in the cyanobacterial group at 5 days postexposure, 20000x. (f) The fading of nucleus in the cyanobacterial group at 10 days postexposure, 20000x. (g) The recovery of nucleus in the mixed group after 15 days of detoxification, 22000x. (h) The recovery of nucleus at the end of the experiment in the cyanobacterial group, 16000x.
