Bacteria are single-celled organisms that exist in a variety of environments, but the most pertinent types of bacteria in medicine are the kind that exists in our bodies and the kind that is pathogenic. Some bacteria can protect us from disease while other types can cause it.
Just like in humans, dogs have naturally-occurring bacteria in their bodies that provide many benefits. These beneficial bacteria can help with food digestion while others block harmful bacteria from accumulating and causing disease. Regardless of their beneficial or harmful properties, all bacteria can be placed into one of two categories: aerobic bacteria and anaerobic bacteria. What does this mean, and what happens if your dog develops an infection from anaerobic bacteria?
