Anaplasmosis and ehrlichiosis are the terms used to describe the diseases caused by bacterial organisms known as Anaplasma and Ehrlichia, respectively. Many of the Anaplasma organisms were previously classified as Ehrlichia so you may still see them referred to that way in some references.
Anaplasmosis and Ehrlichiosis in Dogs
Anaplasmosis and ehrlichiosis are both diseases that are carried by ticks. When an animal or person is bitten by an infected tick, they can become infected with the disease.
Signs in Dogs
Signs seen in dogs for both diseases can range from subclinical (showing little to no sign of disease) to life-threatening.
When seen, signs may include:
- Lack of appetite
- Weight loss
- Bloody noses
- Joint pain and stiffness
- Swollen lymph nodes
- Eye disease
- Neurological abnormalities
Anaplasma and Ehrlichia Infections in People
People become infected with anaplasmosis and ehrlichiosis in essentially the same way that dogs do, through the bite of an infected tick. Typically, neither disease is passed directly from your dog to you. However, your dog can bring ticks into your home that can endanger you and your family.
In people, these diseases are also sometimes referred to as human monocytic ehrlichiosis or human granulocytic ehrlichiosis (HGE), although HGE is most commonly referred to now as human anaplasmosis.
Prevention for Your Family and Your Pets
Since ticks are the means by which these diseases are transmitted, it makes sense that preventing tick bites and controlling ticks is the best method of preventing infection.
Consider using an effective flea and tick control product for your dog. Check all pets thoroughly for ticks on a regular basis and remove them promptly when found.
Check yourself thoroughly for ticks if you have been outdoors, particularly if you have been in a wooded area or another high-risk tick environment. Check your children thoroughly as well. Remove any ticks found promptly using tweezers. Pull upward with steady pressure and close to the skin. Immediately clean the bite with soap, water, or rubbing alcohol. Dispose of a live tick by placing it in a tightly sealed bag or container with alcohol. Consider using insect repellent when planning to visit areas likely to be infested with ticks.
Take measures to keep ticks out of your yard. Keep your grass mowed short and remove any high grasses or brush from near your house. Make your yard less tick-friendly by planting mint, sage, or marigolds as a way to deter the insect. Discourage tick-carrying deer and mice into your yard. But invite birds that eat ticks, such as robins and bluebirds. Ticks are also adverse to garlic, onions, asparagus, tomatoes, and sunflower seeds.
