Pathogenic bacteria are the type of microorganisms that can cause infections and are frequently found on various environmental surfaces. These bacteria possess the ability to invade host tissues and overcome the body's defenses, leading to disease states. They can be transmitted through direct contact or by touching contaminated surfaces, making it crucial for cosmetology professionals to understand how to minimize risks and maintain hygiene in their work environments.

In contrast, non-pathogenic bacteria, which can be found in many places, do not cause disease and are often harmless or even beneficial. Beneficial bacteria play a vital role in processes like digestion and maintaining healthy skin microbiomes, and commensal bacteria live on the skin without causing harm in healthy individuals but can sometimes lead to problems if they enter a different environment or if the host's immune system is compromised.

Thus, the recognition of pathogenic bacteria is essential in the cosmetology field, as professionals must implement rigorous cleaning and disinfection protocols to protect themselves and their clients from potential infections.
