Aha! Very good question. I am observing them under the microscope regularly. I watch for trends in immune-cell functions and the reproductive cycles of the menace. It is very hard to tell. These guys will go into cycles based on level of population drop, and immune-cell activity. I guess they also index the cycles to the amount of damage they take from anti- parasite treatment. I know for a fact that they are adapting to the "brew" I make.
The oocyts are also motile. This came as a surprise to me. I need my "new" microscope to investigate how this is.
The parasites work best at night in deep sleep. This is probably when they sabotage the signaling pathways and receptors. They could be producing their own inter-cellular signaling proteins [molocules?] and using the bodys nervous system to communicate. I do see the adult protozoans interacting.
