What kind of diseases do these parasites introduce? Tapeworms are the main threat that fleas bring. Ticks carry Lyme Disease, Rocky Mountain Spotted Fever, Babesia, Ehrlichia and several other infectious diseases. In addition, both of these parasites can lead to anemia, especially in very young or very old animals.
Fleas have been associated with humans and other animals for thousands of years. A bacterium (Yersinia pestis) spread by fleas killed 25 million people, more than a quarter of the European population, in 14 th century Europe. This was the âblack plague.â Epidemics also occurred in Egypt, Africa, China, India and even the U.S., before the discovery of antibiotics.
