What are one-celled microorganisms that can be disease-producing or non-disease producing called?

One-celled microorganisms that can be either disease-producing or non-disease producing are referred to as bacteria. Bacteria are incredibly diverse and can be found in almost every environment on Earth. They play essential roles in processes such as digestion and nutrient cycling in ecosystems, but some bacteria can also cause infections and diseases in humans, animals, and plants.

This dual nature of bacteria, being both beneficial and pathogenic, highlights their importance in both health and disease management. Understanding the characteristics of bacteria is crucial in fields like medicine and esthetics, especially when considering hygiene, sanitation, and infection control practices.
