The brown dog tick is known to transmit diseases to which of the following?

• A. Humans only
• B. Other dogs only
• C. Humans and other dogs
• D. Neither humans nor dogs

Answer: (B)

The brown dog tick is a disease vector that primarily targets dogs. It transmits several pathogens that cause conditions in canines, such as ehrlichiosis, anaplasmosis, babesiosis, and hepatozoonosis. While ticks can bite humans, this particular species is not known as a major source of disease in people; human infections from brown dog ticks are not commonly documented. Because its role as a vector is mainly for dogs, the best answer is that it transmits diseases to other dogs only. In practical terms, controlling ticks on dogs helps prevent these canine diseases and reduces the risk of spreading to other dogs in the same environment.
