Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores. It is related to pathogens Yersinia enterocolitica, and Yersinia pseudotuberculosis, from which it evolved.

鼠疫（Pestis）是由鼠疫杆菌引起的 自然疫源性 烈性传染病，也叫做 黑死病 。 临床主要表现为 高热 、 淋巴结 肿痛、 出血倾向 、肺部特殊炎症等。 远在2000年前即有记载。

Y. pestis infection may cause five principal forms of plague, including bubonic, septicemic, pneumonic, meningeal, and pharyngeal plague . In addition, Y. pestis may cause skin ulceration at its portal of entry, reported as carbuncles and ulcers, along with pustules, spots, petechiae, bruising, and gangrene .

鼠疫耶爾森菌 [1] （学名： Yersinia pestis ）又稱鼠疫耶氏桿菌 [2] ，俗稱鼠疫桿菌（plague bacillus），是一種桿菌，屬於腸桿菌科 耶爾森菌屬，同時也是腺鼠疫、肺鼠疫和敗血性鼠疫的病原體。

Plague is a potentially life-threatening disease caused by the bacterium, Yersinia pestis. Plague occurs naturally in areas of the western United States, where it circulates among wild rodents and other animals. Plague can be cured with antibiotics, but treatment must be given quickly.

2022年7月7日 · Plague is caused by the bacteria Yersinia pestis, a zoonotic bacteria usually found in small mammals and their fleas. People infected with Y. pestis often develop symptoms after an incubation period of one to seven days. There are two main clinical forms of plague infection: bubonic and pneumonic.

2025年3月25日 · Yersinia pestis, bacterium in the family Yersiniaceae (order Enterobacterales) that causes plague. Yersinia pestis is classified as a Gram-negative coccobacillus, being spherical to cylindrical in shape and having a thin peptidoglycan cell wall surrounded by an outer lipopolysaccharide membrane.

2024年5月21日 · Plague is caused by Yersinia pestis bacteria. It can be a life-threatening infection if not treated promptly. Plague has caused several major epidemics in Europe and Asia over the last 2,000 years. Plague has most famously been called "the Black Death" because it can cause skin sores that form black scabs.

Y. pestis displays a quite unique set of virulence factors that allow successful infection of fleas and subversion of immune responses in mammalian hosts, leading to rapid host death in the absence of adequate treatment. In this article, we review recent advances in plague research, particularly in the fields of evolution, virulence ...
