Bacterial Infections
Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most bacteria won’t hurt you. Less than 1% of bacteria makes people sick. Many bacteria are helpful. Some bacteria help to digest food, destroy disease-causing cells and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese.
But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.
A bacterial infection is the detrimental colonization of a host organism by a foreign species. In a bacterial infection, the infecting organism seeks to utilize the host’s resources to multiply (usually at the expense of the host). The infecting organism, or pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death. The host’s response to infection is inflammation. Colloquially, a pathogen is usually considered a microscopic organism though the definition is broader, including feces, parasites, fungi, viruses, prions, and viroids.
Antibiotics are the usual treatment. When you take antibiotics, follow the directions carefully. Each time you take antibiotics, you increase the chances that bacteria in your body will learn to resist them.

Health Tips
Excercise. More than 50% of American men and women do not get enough physical activity to provide health benefits. For adults, thirty minutes of moderate physical activity on most, preferably all, days of the week is recommended. It doesn't take a lot of time or money, but it does take commitment. Start slowly, work up to a satisfactory level, and don't overdo it. You can develop one routine, or you can do something different every day. Find fun ways to stay in shape and feel good, such as dancing, gardening, cutting the grass, swimming, walking, or jogging. Read more Health Tips »
