Plague pestis

Bacterial agents, such as Bacillus anthracis (the causative agent for anthrax), or Yersinia pestis (the causative agent for plague). 

Plague is an infectious disease that affects animals and humans. It is caused by the bacterium Yersinia pestis. This bacterium is found in rodents and their fleas and occurs in many areas of the world, including the United States. 

Bubonic plague is the most common form of plague. This occurs when an infected flea bites a person or when materials contaminated with Y. pestis enter through a break in a person s skin. Patients develop swollen, tender lymph glands (called buboes) and fever, headache, chills, and weakness. Bubonic plague does not spread from person to person. 

A member of the Aryan Nations neo-Nazi organization was arrested in Ohio on charges of mail and wire fraud. He allegedly misrepresented himself when ordering three vials of freeze-dried Yersinia pestis, a bacterium that causes plague, from a Maryland biological laboratory. 

Second, we have to compare the rate of scientific progress in the AIDS epidemic with other epidemics that have had great impacts on society for example, the Black Death (plague) caused by Yersinia pestis. Plague caused a major epidemic in the fifth century and a second major epidemic in the fourteenth century. The infectious agent Yersina pestis was isolated in 1908. Effective therapy against the disease had to wait for the development of classical antibiotics in the 1940s. 

Tapeworm infections are caused by Taenia solium. Tinea pedis causes the fungal infection known os athlete s foot. Yersinia pestis is implicated in plague, Candida albicans is responsible for candidiasis while Chlamydia frachomifis causes eye infections.

Plague is caused by Yersinia pestis, bacteria that are carried through infected flea bites, direct contact, and by inhalation of infective materials. Bubonic plague is the most common form of plague and is derived from the bite of a flea that fed previously on infected animals. Pneumonic plague causes the greatest amount of mortality and is transmitted by aerosol. It...

During World War II, the Japanese dropped fleas infected with plague (Yersinia pestis) on Chinese cities, killing hundreds and possibly thousands. Thousands of documents captured from the Japanese following the war further attest to the Japanese use of anthrax, typhoid, and plague on Manchurian towns and cities. This information proved to be a stimulus for the United States to seriously begin to study the area of germ warfare. 

Skurnik, M., Peippo, A., Ervela, E. Characterization of the O-antigen gene clusters of Yersinia pseudotuberculosis and the cryptic O-antigen gene cluster of Yersinia pestis shows that the plague bacillus is most closely related to and has evolved from Y. pseudotuberculosis serotype O lb. Mol Microbiol 37 (2000) 316-330.
