Murine Typhus is transmitted by which type of flea?

Murine Typhus is primarily transmitted by the Oriental rat flea. This flea typically infests rats and can also bite humans, serving as the vector for the disease. When a flea bites an infected rat and then bites a human, it can transmit the Rickettsia typhi bacterium responsible for Murine Typhus. The Oriental rat flea has a close association with rodents, which are crucial reservoirs for the bacteria.

Other flea types listed do not significantly contribute to the transmission of Murine Typhus. For example, the dog flea primarily infests dogs and is not a known vector for this disease. Similarly, the horse flea and human flea do not play a significant role in the epidemiology of Murine Typhus. Therefore, understanding the ecological and behavioral characteristics of the Oriental rat flea enhances the comprehension of vector control and prevention strategies for the disease.
