Bacteria are microscopic organisms that can exist in various environments and have a wide range of effects on human health. They are unicellular, meaning they consist of a single cell, and many species can cause infections in humans, animals, and plants. Understanding bacteria is crucial in the context of tattooing, as proper sanitation and sterilization practices are essential to prevent bacterial infections that can arise from the tattooing process. Awareness of how bacteria function and their potential impact on skin integrity helps ensure the safety and health of clients receiving tattoos.
