plague

Examples of plague in the following topics:

• Plague

  • The plague is an infectious disease caused by the Gram-negative rod-shaped bacteria Yersinia pestis.
  • The plague is an infectious disease caused by the Gram-negative rod-shaped bacteria Yersinia pestis .
  • The plague also has a detrimental effect on non-human mammals.
  • Although bubonic plague is often used synonymously with plague, it refers specifically to an infection that enters through the skin and travels through the lymph nodes (buboes).
  • Pneumonic plague manifests as a severe lung infection, and is more virulent and rare than bubonic plague.

• Arthropods as Vectors

  • The human flea, Pulex irritans, and the Oriental rat flea , Xenopsylla cheopis, are responsible for the transmission of the bubonic plague, murine typhus, and tapeworms.
  • The oriental rat flea is an example of an arthropod vector as it is the primary vector of plague.
  • This vector has been the cause of large plague epidemics in Asia, Africa, and South America.

• Ecology, Epidemiology, and Evolution of Pathogens

  • The Black Death (plague) of the 14th century reduced the world population from an estimated 450 million to 350 - 375 million .
  • An animation of the plague that spread through the world during the pandemic in the 14th century.

• Tularemia

  • Tularemia (also known as Pahvant Valley plague, rabbit fever, deer fly fever, and Ohara's fever) is a serious infectious disease caused by the bacterium Francisella tularensis.
  • Inflammation spreads to the lymph nodes, which enlarge and may suppurate (mimicking bubonic plague), accompanied by a high fever.

• Disease Reservoirs and Epidemics

  • Bubonic plague: marmots, black rats, prairie dogs, chipmunks, and squirrels for bubonic plague
  • The migrations of certain animals, such as rats, are in some cases responsible for the spread of plague, from which these animals die in great numbers.

• Gammaproteobacteria

  • (enteritis and typhoid fever), Yersinia pestis (plague), Vibrio cholerae (cholera), Pseudomonas aeruginosa (lung infections in hospitalized or cystic fibrosis patients), and Escherichia coli (food poisoning).

• Bacterial Pneumonias

  • Pneumonia caused by Yersinia pestis is usually called pneumonic plague.

• Defining Microbes

  • The organisms involved include pathogenic bacteria, which are the cause of diseases such as plague, tuberculosis and anthrax.

• Koch and Pure Culture

  • By using his methods, Koch's pupils found the organisms responsible for diphtheria, typhoid, pneumonia, gonorrhoea, cerebrospinal meningitis, leprosy, bubonic plague, tetanus, and syphilis.

• Babesiosis

  • The more severe cases are plagued with high fevers, shaking chills, and severe anemia, similar to symptoms seen in individuals infected with malaria.
