Yersinia pestis bubonic plague

Plague is an infectious disease caused by Yersinia pestis, a naturally occurring bacterium found primarily in wild rodents. Plague has been the cause of 3 of the great pandemics of the modern era-in the mid-6th century, the mid-14th century (known as the Black Death), and the early 20th century Bubonic plague is one of three types of plague caused by the plague bacterium (Yersinia pestis). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting, as well as swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. Occasionally, the swollen lymph nodes, known as. Bubonic plague is the most common form of plague and is caused by the bite of an infected flea. Plague bacillus, Y. pestis, enters at the bite and travels through the lymphatic system to the nearest lymph node where it replicates itself. The lymph node then becomes inflamed, tense and painful, and is called a 'bubo'

Plague is a disease that affects humans and other mammals. It is caused by the bacterium, Yersinia pestis. Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with plague. Plague is infamous for killing millions of people in Europe during the Middle Ages Background The plague bacterium (Yersinia pestis) exists in enzootic cycles of rodents and their fleas in the western United States. People are infected with the plague bacterium through flea bites and direct contact with infected animal tissues or fluids. People are also infected by inhalation of droplets coughed by an infected human or animal The bacterium Y. pestis causes deadly plague, whereas the other two closely related enteropathogenic Yersinia species merely cause limited gastrointestinal manifestations. Y. pestis has unique virulence mechanisms that enable it to be a successful flea-borne and highly virulent pathogen

Plague in humans 'twice as old' but didn't begin as flea

The bacteria that cause plague, Yersinia pestis, maintain their existence in a cycle involving rodents and their fleas. Plague occurs in rural and semi-rural areas of the western United States, primarily in semi-arid upland forests and grasslands where many types of rodent species can be involved

  1. Plague or black death is an infection of rodents caused by Yersinia pestis and accidentially transmitted to humans by the bite of infected fleas. The disease follows urban and sylvatic cycles and is manifested in bubonic and pneumonic forms [note: bubo is derived from a Greek word for groin]
  2. 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
  3. Yersinia pestis. Y. pestis is the cause of bubonic, septicemic, and pneumonic plague. Plague is a zoonotic infection with its reservoirs in rodents and other animals. Humans can be considered accidental victims when they are bitten by rodent fleas or handle animal tissues or, rarely, inhale airborne bacteria from coughing patients or from.
  4. Primary pneumonic plague results from inhalation of Y. pestis bacteria and would be the expected form of disease following an aerosol attack with Y. pestis. Secondary pneumonic plague can occur if bubonic or septicemic plague goes untreated and the plague bacteria are allowed to spread to the lungs. • Bubonic plague is the most common form of.
  5. What is the Plague (Yersinia Pestis)? 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
  6. Plague is also transmissible person to person when in its pneumonic form.
