They are gram -ve, capsulated, catalase +ve, oxidase -ve, indole -ve, non-motile rod shape organism Author Summary Inhalation of the bacterium Yersinia pestis results in primary pneumonic plague, a severe necrotizing pneumonia with mortality rates approaching 100% in the absence of timely antibiotic administration. Despite the notoriety of Y. pestis as a potential biological weapon and its well-established pandemic potential, very little is known regarding early host-pathogen interactions. Yersinia pestis (formerly Pasteurella pestis) is a Gram-negative rod-shaped bacterium.It is a facultative anaerobe that can infect humans and other animals. Human Y. pestis infection takes three main forms: pneumonic, septicemic, and the notorious bubonic plagues.  All three forms are widely believed to have been responsible for a number of high-mortality epidemics throughout human.
Sometimes referred to as the black plague, the disease is caused by a bacterial strain called Yersinia pestis. This bacterium is found in animals throughout the world and is usually. With the first of those mutations, ancient strains of plague bacteria (Yersinia pestis) gained the ability to cause pneumonic plague — a respiratory form of the disease that spreads easily when. Plague is a severe infection caused by the gram-negative bacteria Yersinia pestis and often involving the lymph nodes and/or lungs. The bacteria are spread mainly by the rat flea.

Three Yersinia species are known to be pathogenic to humans: Yersinia enterocolitis, Y. pseudotuberculosis, and Y. pestis.Y. enterocolitis and Y. pseudotuberculosis are enteropathogenic bacteria causing enteritis, ileitis, and mesenteric lymphadenitis, whereas Y. pestis is the causative agent of bubonic plague, among the most deadly human infectious disease in history Infection with Yersinia pestis starts with flu-like symptoms but then rapidly progresses in serious illness, which differs according to the route of infection. Bubonic plague, the most common, has an incubation of 2-6 days, and is characterised by regional lymphadenopathy resulting from cutaneous or mucous membrane exposure
Yersinia pestis is a gram negative, rod-shaped, facultative anaerobic bacterium, known for causing the plague.Y. pestis was first discovered by a French-born Swiss bacteriologist named Alexander Yersin in 1894. Yersin stumbled upon this bacterium while in China studying a plague epidemic there. However, before then, Y. pestis has been wreaking havoc throughout human history Plague is a disease caused by Yersinia pestis that affects rodents (e.g., squirrels, prairie dogs, or mice), other mammals (e.g., rabbits or hares), and humans. These bacteria are found in many areas of the world, including the western United States. There are three forms of plague: bubonic (lymph node infection), pneumonic (lung infection) and. Plague is a vector-borne infectious disease caused by the bacteria known as Yersinia pestis. Plague has a high fatality rate, and people have described outbreaks of the bacterial infection for centuries. In the Middle Ages, plague was known as the Black Death. It caused the death of 60% of the population of Europe during a pandemic (an. Introduction. Yersinia pestis, the causative agent of plague, usually harbours three plasmids (pPCP1, pMT1 and pCD1) that are necessary for the complete virulence of the pathogen; two of them, pPCP1 and pMT1, are species-specific while pCD1 is conserved among three human pathogenic yersiniae: Y. pestis, Yersinia pseudotuberculosis and Yersinia enterocolitica
Yersinia Pestis. The Plague was originated from a gram- negative bacterium, that is rod-shaped by the name of yersinia pestis. The bacterium comes in three different forms: bubonic, septicemic, and pneumonic.

Biology & Genetics of Yersinia pestis. NIAID-supported investigators sequenced the genome of the strain of Yersinia pestis that was associated with the second pandemic of plague, including the Black Death. This will provide a valuable research resource to scientists for identifying new targets for vaccines, drugs, and diagnostics for this. Treatment consists of taking antibiotics for at least 7 days. How quickly would someone get sick if exposed to plague bacteria through the air? Someone exposed to Yersinia pestis through the air—either from an intentional aerosol release or from close and direct exposure to someone with plague pneumonia—would become ill within 1 to 6 days The genus Yersinia includes pestis (cause of plague), enterocolitica and pseudotuberculosis. Each can produce severe and potentially life-threatening disease if you become infected. Generally the latter two produce gastroenteritic infections and can mimic appendicitis
Yersinia enterocolitica is a type of gram-negative bacteria which most commonly infects young children. However, numerous studies have linked this pathogen with some people who have Graves' Disease.
