Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. [1] They are caused by infection with a variety of pathogens , including rickettsia and other types of bacteria , viruses , and protozoa . [ 2 ]
The tick-borne encephalitis virus is known to infect a range of hosts including ruminants, birds, rodents, carnivores, horses, and humans. The disease can also be spread from animals to humans, with ruminants and dogs providing the principal source of infection for humans. [4]
Fleas are vectors for viral, bacterial and rickettsial diseases of humans and other animals, as well as of protozoan and helminth parasites. [35] Bacterial diseases carried by fleas include murine or endemic typhus [34]: 124 and bubonic plague. [36] Fleas can transmit Rickettsia typhi, Rickettsia felis, Bartonella henselae, and the myxomatosis ...
The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis. The plague, fevers, tularemia: The diseases fleas can carry and how to ...

Lyme disease is an infection caused by spiral-shaped bacteria known as spirochete, ... resulting in arthritis, bone and joint pain, additional rashes, inflammation of the brain and spinal cord and ...
Ticks and lice form another large group of invertebrate vectors. The bacterium Borrelia burgdorferi, which causes Lyme Disease, is transmitted by ticks and members of the bacterial genus Rickettsia are transmitted by lice. For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus.
These bacteria are typically transmitted to humans through the bites of infected arthropods, such as ticks, fleas, and lice. Rickettsial diseases are characterized by a range of symptoms, which can vary depending on the specific type of rickettsial infection but often include fever, headache, rash, and muscle aches.
