What is Yersinia Pastis?
Yersinia Pastis is an alternative spelling yersinia pestis, and refers to the tribe of bacteria. These bacteria were associated with black plague and remain active in the modern world, although it is generally limited to a limited number of animal tanks. yersinia pastis is anaerobic and gram-negative. Infection with this microbe, although very serious, can be successfully treated with modern antibiotics, although some strains seem to develop antibiotic resistance.
This microbe was first identified and connected with the plague at the end of the 19th century, a connection that has since been convincingly proven by DNA testing. The discovery of yersinia pastis allowed scientists to combine a complete understanding of the typical cycle of the disease in black plague. Bacteria are usually carried by a host species of a small mammal, usually rats, marmots or similar animals. The fleas then transfer the microb to manasts. Play transmission to humans is also possible, but is generally a secondary form of transmission.
Three forms of infection yersinia pastis are generally seen in humans. The most common diversity of infection, directly transmitted by fleas, leads to bubonic plague, the most common form of plague that creates a painful swelling in the lymph nodes and many general systemic symptoms. The septicemic plague occurs when the microbe is able to directly infect the bloodstream and is a very dangerous form of the disease, especially when it is not treated. Pneumonic plague is a lung infection and also extremely serious, last but not least because it produces an arc cough that allows the microbe to infect new hosts through air transmission.
Yersinia Pastis is endemic in many areas of the world, including Southeast Asia and the American Southwest. The head of plague has been rare in the modern world and has not occurred in the United States since the 1920s. However, this microbe remains a threat, infectedE 1,000 to 2,000 people per year and kills about one of the seven of them.
Antibiotics are currently highly effective in dealing with yersinia pastis , but recent research suggests that resistance can increase. Bacteria are often able to exchange DNA elements in the wild and it seems that yersinia pastis has been able to obtain genes that produce antibiotic resistance with other, more common bacteria. These bacteria developed a drug resistance in response to widespread use, frequent excessive use and abuse of antibiotics.
