Latecomers in immunesystem evolution, B-cells, like this specimen covered with bacteria, produce armies of anti-bodies whose sole purpose is to attack a single kind of pathogen.

On the attack
Malaria protozoa have multiplied in two cells in a culture dish of red blood cells. One has burst open releasing the parasites to infect other cells.
