Frequent question: Which describes an organism that carries a pathogen to a susceptible host?

What organisms transmit pathogens?

Common vehicles: Contaminated food, water, blood, or other vehicles may spread pathogens. Microorganisms like E. coli and Salmonella enter the digestive system in this manner. Vectors: Creatures such as fleas, mites, and ticks—called vectors—can also transmit disease.
