What is true about most bacteria?

Most bacteria are nonpathogenic, meaning they do not cause disease in humans or other organisms. This characteristic is essential for understanding the role of bacteria in our environment and their relationship with health and wellness. Nonpathogenic bacteria can be beneficial, aiding in processes like digestion or even helping to protect against pathogenic bacteria by outcompeting them for resources.

While there are pathogenic bacteria that can cause infections and illnesses, the presence of nonpathogenic bacteria is far more common. They reside in diverse environments, including soil, our skin, and various surfaces, not just in salons or water. Therefore, recognizing that most bacteria are nonpathogenic allows for a more nuanced perspective about their existence and impact on the human body and overall public health.
