Apicomplexan parasites undergo a sexual cycle in their definitive host, and many also undergo extensive asexual replication in their intermediate host or hosts. The research goals are to define the genes of the host To the best of our knowledge, this may be a new benefit that host P. bursaria gain from harboring symbiotic algae.
