One type of microorganism, the virus, has a huge impact on our everyday lives, causing colds, flus, stomach aches. What is a virus, and how is it different, for example, from bacteria? Roll on over to Manchester Children’s University site to play around with beginning facts about viruses and bacteria. (You can also become an expert on mushrooms and other fungi.) And how do these tiny threats get in our body and get us sick? Watch the adventures of the inept "Staph Sargent" and his trusty sidekick as they try to infect the world with germs. And while the Staph Sargent can be defeated by hand-washing, purses are carrying even more bacteria and viruses, as seen in this newscast.
To get up close and personal with these mischief-making microorganisms, you can browse the fascinating and legally downloadable images at the World of Viruses. To see a picture of a specific microorganism, you can also investigate at, Microbe World Beta. For more light-hearted death and destruction, you can read a Virus Comic Book such as the Frozen Horror or infect the world at the almost too realistic Plague Inc game.
