1. Amoebaegraze on biofilm consuming bacteria for food but are
2. infected by legionella which
3. grows intracellularly and then
4. overwhelms its protozoan host cell, differentiates into mobile cells and
5. causes lysis of the host cell releasing hundreds or thousands of infective progenyin search of new hosts to infect
