This volume in the Graphic Science series includes discussions of the discovery of the life-form, good and bad bacteria, and standard public health routines related to their containment and, when positive, use. The guide through all of this, Max Axiom, is described in between the final glossary and the index, so readers may want to head to the end pages first to get a clear sense of his persona. Brightly colored artwork and correct, if brief, information make this a good purchase to introduce some basic science concepts, or where the series is already established.
