Information for Patients


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 percent of the different types make people sick. Many 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.

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 causing antibiotic resistance. Later, you could get or spread an infection that those antibiotics cannot cure.

Tick Bites

If you spend time outdoors or have pets that go outdoors, you need to beware of ticks. Ticks are small bloodsucking parasites. Many species transmit diseases to animals and people. Some of the diseases you can get from a tick bite are Lyme disease, ehrlichiosis, Rocky Mountain spotted fever and tularemia.

Some ticks are so small that they can be difficult to see. Ticks may get on you if you walk through areas where they live, such as tall grass, leaf litter or shrubs.

Tick-borne diseases occur worldwide, including in your own backyard. To help protect yourself and your family, you should

  • Use a chemical repellent with DEET, permethrin or picaridin
  • Wear light-colored protective clothing
  • Tuck pant legs into socks
  • Avoid tick-infested areas
  • Check yourself, your children and your pets daily for ticks and carefully remove any ticks you find
