Rickettsia pathogens are a group of bacteria that cause a set of illnesses known as rickettsioses. These organisms are obligate intracellular bacteria, meaning they must live inside host cells to reproduce. They’re typically spread by arthropod vectors such as ticks, lice, or fleas. Because the diseases are caused by bacteria, not viruses or protozoa, the most precise way to describe the agents is to name the genus Rickettsia. So these diseases are caused by Rickettsia bacteria, with examples like Rocky Mountain spotted fever and typhus.
