Come meet the good, the bad, and the ugly--yes, germs!
There's so much to discover about germs. Did you know that germs make
your stomach growl as they break down your food? Or that they can travel
the world on anything from fleas and ticks to trains and buses?
Told from the perspective of Sam the Salmonella, this informative
picture book introduces young readers to helpful and harmful germs,
exploring their discovery; the breakout of historic diseases; the
invention of pasteurization, vaccination, and penicillin; and other
fascinating details about the world of microscopic organisms.
