Great importance as they carry bubonic plague and murine typhus from rats and those that transmit plague among wild rodents and occasionally to humans. * Fleas cause insidious attacks on man and domestic animals, causing irritation, loss of blood, and extreme discomfort. Serve as intermediate hosts for some species of dog and rodent tapeworms that occasionally infest man, and they may act as intermediate hosts of a filarial worm of dogs. * Fleas may possibly be involved as vectors of Salmonella bacteriacausing diarrhea and dysentery and of the bacteria causing tularemia.

Answer 15
