What term describes organisms that are capable of being transported in blood?

The correct term for organisms that can be transported in blood is "bloodborne." This term specifically refers to pathogens, such as certain viruses and bacteria, that are present in the bloodstream and can be transmitted from one individual to another through blood. Bloodborne pathogens are of significant concern in healthcare and laboratory settings due to their potential to cause infections through needlesticks, blood transfusions, or other means of exposure to contaminated blood.

The other terms refer to different modes of transmission. "Foodborne" refers to pathogens that are transmitted through contaminated food or water. "Vectorborne" describes organisms that are transmitted by vectors, such as insects, which can carry diseases from infected hosts to new hosts. "Waterborne" indicates pathogens that are spread through contaminated water sources. Each of these terms highlights different routes by which infectious agents can be spread, making "bloodborne" the precise choice for organisms transmitted via blood.
