"The Good, the Bad, and the Deadly"
The pearly droplets in this photo are colonies of Bacillus anthracis, the bacterium that causes anthrax.
The bugs exude a goopy coating that repels immune system assaults and allows them to establish a foothold
in the body. Learn more about the tricks bacteria use to prosper almost everywhere on Earth in this Web text
from microbiologist Kenneth Todar of the University of Wisconsin, Madison. High school and college students
can absorb the basics of bacterial structure, physiology, classification, and ecology.The book emphasizes
medical microbiology, exploring how bacteria hitch a ride from host to host, how the body tries to corral
invading microbes, and how the bugs elude these defenses. For example, the cholera bacterium releases a
toxin that induces intestinal cells to spill ions and water, producing potentially lethal diarrhea.
