Ehrlichia granulosis is zoonotic & carried by which species?

• A. Dog
• B. Cat
• C. Horse
• D. Sheep

Answer: (A)

Ehrlichia species are tick-borne bacteria, and the dog is the host commonly associated with this organism in veterinary medicine. Dogs can carry the bacterium and act as a reservoir; ticks feeding on an infected dog can transmit it to other animals or to humans, making the infection zoonotic. Among the animals listed, the dog is the species most closely linked to harboring this agent. Cats, horses, and sheep are not the typical reservoir hosts for this Ehrlichia; they may be exposed, but the dog is the principal carrier in the usual context. The idea to remember is that the dog serves as the reservoir that enables tick transmission to other hosts, including humans.
