Yersinia pestis - Bacteria Virulence and Symptoms Essay -- Biology Med

Yersinia pestis - bacteria Virulence and SymptomsYersinia pestis appeared fairly early in history and is still everyday today. humankinds have come in contact with this bacterium in massive outbreaks throughout history, including the most famous sinister Death of the fourteenth century. From the lack of knowledge of the bacteria and its ability to infect populations rapidly, the human speed has suffered immensely. The bacterium is specialized with specific plasmids, Yersinia outer proteins as salutary as other toxins that it uses to disrupt the bodys immune response. Through this, Yersinia pestis avoids harm and effectively infects the circulative system of its host causing three tunes of the plague Bubonic, Pneumonic and Septicemic. separately form of the plague can develop into a case of compulsion as the host experiences painful symptoms, including the large, inflamed bubo.One of the most well known pandemics known to mankind is the plague, also known as the Black Death, which plundered areas from Asia to Western Europe and carried on to the Americas. Though the infection is non the most prevalent compared to many of the worlds other bacterial agents, the plague is unmatchable of the most feared. Normally, Yersinia pestis is a zoological disease, affecting small mammals and their fleas. However, the most important outbreak in humans occurred in the 14th century, primarily caused by the rapid movement of rats carrying an infected rat flea, or Xenopsylla cheopis. The bacterium, Yersinia pestis, transferred quickly from individual to person as the growing population became infected with the contagious form of the plague. And during Europes worst outbreak, the lack of scientific knowledge increased the fatality of the Yersinia pestis bacteria.
