What are pathogenic microorganisms present in human blood referred to as?

Pathogenic microorganisms present in human blood are referred to as bloodborne pathogens. This term specifically denotes those infectious agents that can be transmitted through blood and other bodily fluids. Bloodborne pathogens include viruses, bacteria, and other microorganisms that are capable of causing diseases such as HIV, Hepatitis B, and Hepatitis C.

Understanding this terminology is crucial in environments like tattoo parlors, where the risk of exposure to blood and bodily fluids is higher. Proper training and safety protocols are essential to protect artists and clients from potential infections and to ensure that all materials and procedures handled are suitable to minimize risks associated with these pathogens.

The other terms listed do not specifically pertain to microorganisms in blood. Infectious agents, for example, is a broader category that can include pathogens not just from blood but from various sources. Hazardous materials refer to substances that can cause harm but are not limited to biological agents. Carcinogenic substances refer specifically to agents that can cause cancer, which is unrelated to the transmission of pathogens through blood.
