Meet the bacteria, viruses, and other germs and microbes that are all around, but too small for us to see, in this children's science book by bestselling author and science comedian Steve Mould. What do a squid that glows, fungus that grows, and tiny creatures in the soil under your toes all have in common? Find out in this dynamic and engaging book all about bacteria, viruses, and other germs and microbes. The Bacteria Book perfectly walks the line between "ew, gross!" and "oh, cool!", exploring why we need bacteria and introducing readers to its microbial mates: viruses, fungi, algae, archaea, and protozoa.
