What is a characteristic of nonpathogenic bacteria?

Nonpathogenic bacteria are defined by their role in human health and the environment. These organisms are inherently harmless and can often be beneficial, as exemplified by probiotics, which are live microorganisms that provide health benefits when consumed. Probiotics play a vital role in digestion, enhance the immune system, and can help restore the natural balance of bacteria in the gut. This positive contribution to health illustrates the essential characteristic of nonpathogenic bacteria as being supportive rather than harmful.

This beneficial nature distinguishes them from pathogenic bacteria, which are associated with illness and disease. Understanding the differences between these types of bacteria is crucial for estheticians, as knowledge about skin microbiota and the importance of maintaining a healthy balance of bacteria can influence skincare treatment decisions and educate clients on the best practices for skin health.
