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.

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 ...
The foregut of this flea is blocked by a Y. pestis biofilm; when the flea attempts to feed on an uninfected host, Y. pestis from the foregut is regurgitated into the wound, causing infection. The bubonic plague is an infection of the lymphatic system, usually resulting from the bite of an infected flea, Xenopsylla cheopis (the Oriental rat flea ...
The pests affecting trees are predominantly insects, and many of these have also been introduced inadvertently and lack natural enemies, and some have transmitted novel fungal diseases with devastating results. Humans have traditionally performed pest control in agriculture and forestry by the use of pesticides; however, other methods exist ...
Sylvatic plague is an infectious bacterial disease caused by the plague bacterium (Yersinia pestis) that primarily affects rodents, such as prairie dogs. It is the same bacterium that causes bubonic and pneumonic plague in humans. Sylvatic, or sylvan, means 'occurring in woodland,' and refers specifically to the form of plague in rural wildlife.
