What term describes bacteria that can cause disease?

The correct term for bacteria that can cause disease is pathogenic. Pathogenic bacteria have the ability to invade host tissues, evade the immune system, and produce toxins that can harm the host, leading to various diseases. Understanding this term is crucial for anyone in the field of esthetics, as it emphasizes the importance of hygiene and sanitation practices to prevent infections and ensure client safety.

In contrast, non-pathogenic bacteria are those that do not cause disease and are often beneficial, playing roles such as aiding in digestion or protecting against harmful bacteria. Probiotics are a subset of non-pathogenic bacteria that are particularly beneficial to gut health but do not directly cause disease. Symbiotic refers to a broader interaction in which two different organisms live together, often in a mutually beneficial relationship, but this term does not specifically address the potential harmful effects of bacteria.
