bubonic plague
World History
Microbiology
Examples of bubonic plague in the following topics:
-
History of Bacterial Diseases
- From 541 to 750 C.E.., an outbreak of what was likely a bubonic plague (the Plague of Justinian), eliminated one-quarter to one-half of the human population in the eastern Mediterranean region.
- The bubonic plague would strike Europe more than once.
- Bubonic plague struck London hard again in the mid-1600s .
- Although contracting bubonic plague before antibiotics meant almost certain death, the bacterium responds to several types of modern antibiotics; mortality rates from plague are now very low.
- Such was the case with bubonic plague.
-
Plague
- Human Y. pestis infection is manifested in three main forms: pneumonic, septicemic, and the notorious bubonic plagues.
- 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).
- The incubation period of bubonic plague is from 2-6 days, while the bacteria actively replicate.
- Pneumonic plague manifests as a severe lung infection, and is more virulent and rare than bubonic plague.

-
The Black Death
- The Black Death was an infamous pandemic of bubonic plague and one of the most devastating pandemics in human history.
- In the Late Middle Ages (1340–1400) Europe experienced the most deadly disease outbreak in history when the Black Death, the infamous pandemic of bubonic plague, hit in 1347.
- The most infamous symptom of bubonic plague is an infection of the lymph glands, which become swollen and painful and are known as buboes.
- Buboes associated with the bubonic plague are commonly found in the armpits, groin, and neck region.
- Plague brought an eventual end of serfdom in Western Europe.
-
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.
-
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.
-
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.
-
Overcoming Density-Dependent Regulation
- In the fourteenth century, the bubonic plague killed as many as 100 million people: between 30 to 60 percent of Europe's population.
- Today, however, the plague and other infectious diseases have much less of an impact.
-
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.
-
Pisa, Venice, and Milan
- Additionally, the power of the church continued to grow in this period, particularly during the wave of Bubonic Plague that killed as much as a quarter of the population in some cities.
-
Living in Europe
- Additionally, the Black Death caused by the Bubonic Plague killed nearly half the population of Europe through successive waves.
