Two types of germs cause most infections in the United States - viruses and bacteria. They are frequently portrayed as harbingers of disease and death. The news is always reporting about some bacteria or virus such as the human immunodeficiency virus (HIV), cholera, the West Nile virus, or E. coli causing illnesses around the world. Throughout modern and ancient times alike, these unseen organisms have caused the deaths of millions of people.
Most bacteria are harmless, and without them, life on Earth could not exist. They are essential components of the global ecosystem as decomposers. Viruses, on the other hand, are mostly harmful. They exist only to invade cells and reproduce themselves, usually destroying the host cell in the process.
This week we'll look at the differences between viruses and bacteria.
TTFN, Fred.
