Harmful Bacteria:
* Pathogenic bacteria: This is the most common term for bacteria that cause disease. These bacteria can produce toxins, invade tissues, and disrupt normal bodily functions. Examples include Salmonella, E. coli, and Staphylococcus aureus.
* Opportunistic pathogens: These bacteria are normally harmless but can cause disease under certain conditions, like a weakened immune system. Examples include Pseudomonas aeruginosa and Candida albicans.

Non-Harmful Bacteria:
* Commensal bacteria: These bacteria live on or in our bodies without causing harm. In fact, many are beneficial to our health. Examples include E. coli in the gut, which helps us digest food.
* Beneficial bacteria: These bacteria are specifically known for their positive effects on our health. Examples include Lactobacillus and Bifidobacterium, found in yogurt and probiotics, which support gut health.
Other terms:
