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 ...
Plague, a disease that affects humans and other mammals, is caused by the bacterium Yersinia pestis. The human flea can be a carrier of the plague bacterium, although it is an exceptionally very poor vector of transmission. [4] Plague is infamous for killing millions of people in Eurasia during the Middle Ages. Without prompt treatment, the ...
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 ...

Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
The fleas that transmit the disease only directly infect humans when the rat population in the area is wiped out from a mass infection. [16] Furthermore, in areas with a large population of rats, the animals can harbor low levels of the plague infection without causing human outbreaks. [ 15 ]
It is caused by the bacterium Rickettsia typhi, and is transmitted by the fleas that infest rats. While rat fleas are the most common vectors, cat fleas and mouse fleas are less common modes of transmission. These fleas are not affected by the infection. Human infection occurs because of flea-fecal contamination of the bites on human skin.
A pest is any living thing which humans consider troublesome to themselves, their possessions, or the environment. [1] Pests can cause issues with crops, human or animal health, buildings, and wild areas or larger landscapes. [2] An older usage of the word "pest" is of a deadly epidemic disease, specifically plague.
