What are disease-producing bacteria called?

Disease-producing bacteria are classified as pathogenic. These microorganisms have the ability to invade a host organism and cause illness or disease. Pathogenic bacteria can disrupt normal bodily functions and lead to a variety of health issues, ranging from mild infections to serious diseases. Their presence in water supplies is a significant concern for water operators, as they must ensure the safety and quality of drinking water to protect public health.

In contrast, non-pathogenic bacteria do not cause disease and can even play beneficial roles in the ecosystem, such as aiding in digestion or nutrient cycling. Environmental bacteria are those found in natural surroundings, and while some may be harmful, not all of them are pathogenic. Aerobic bacteria require oxygen to survive, but this characteristic does not determine whether they are disease-causing.

Understanding the distinction among these terms is crucial for water operators in managing water safety and addressing contamination issues effectively.
