What is the difference between bacteria and viruses? In Bacteria and Viruses for Kids, you will learn all about these two microorganisms. The first thing you will learn is that not all bacteria are bad. In fact, the majority of bacteria on the planet and in your body are actually good. You can find bacteria in things like yogurt, soy sauce, and pickles! So what are bacteria? They are single-celled organisms so small that you can't see them without a microscope. They don't have a nucleus like other single-celled Common shapes include rods, spirals, and spheres. All these organisms move in different ways too. Some move like swimmers using tail-like structures called flagella. Others stay still and don't move much at all. Then there are some that slither or slide their way around. Most bacteria are not harmful. However, there are some that can make you sick. These are called pathogens. Common pathogens include food poisoning, leprosy, and typhoid fever. To fight these pathogens, you can use antibiotics or antiseptics. You can actually find antiseptics in soaps because it's how you keep your hands clean. Good bacteria, on the other hand, are good for many reasons. They help you digest food and keep your immune system strong. They also break down dead plant and animal material to help keep soil healthy. And, they produce about half of the oxygen in the atmosphere! What about viruses? All viruses are bad. Scientists debate whether these organisms are living or dead because they don't have an organized cell structure and can't reproduce unless they attach themselves to a living cell. The word virus comes from the Latin word for "slimy liquid." These organisms attack healthy cells. As those cells reproduce, the virus reproduces too and spreads. Many kinds can pass from person to person through hand-shaking, food contact, and through water. We hope you and your student(s) enjoyed learning about bacteria and viruses!
