Bacterial diseases include gastritis, ulcers, gonorrhea and meningitis, according to Healthgrades. The diseases spread from one person to another and may cause serious complications, including kidney failure and blood poisoning. As a result, an individual should visit a doctor immediately when the symptoms of bacterial disease appear.
Bacteria are microscopic organisms that usually live on the skin and genitals and in the intestines, notes Healthgrades. While some bacteria are healthy, others cause diseases. Bacteria that cause diseases, known as pathogenic bacteria, include Helicobacter pylori, which causes gastritis and ulcers; Neisseria meningitidis, responsible for meningitis; Neisseria gonorrhoeae, the cause of gonorrhea; and Staphylococcus aureus, which results in infections such as cellulitis, boils, food poisoning, pneumonia and toxic shock syndrome.
The symptoms of bacterial diseases include diarrhea, frequent urination, rashes, nausea and vomiting, abdominal pain, and fatigue, states Healthgrades. The diseases may also result in life-threatening symptoms such as seizure, high fever and difficulty breathing. However, symptoms may differ from one person to another based on the underlying bacterial infection, the affected area of the body, and the age and medical history of the patient. Additionally, a sufferer of other diseases, such as influenza and colitis, may experience symptoms that are similar to those of bacterial diseases.
