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

Yersinia pestis - Bacteria Virulence and SymptomsYersinia pestis appeared fairly early in record and is still prevailing today. pityings have come in concussion with this bacterium in massive outbreaks throughout history, including the most famous faint Death of the fourteenth century. From the lack of knowledge of the bacteria and its ability to befoul populations rapidly, the human race has suffered immensely. The bacterium is specialized with specific plasmids, Yersinia outer proteins as well as other toxins that it uses to disrupt the bodys immune response. Through this, Yersinia pestis avoids handicap and effectively infects the circulatory system of its host causing three forms of the smite Bubonic, Pneumonic and Septicemic. Each form of the plague can develop into a case of fatality as the host experiences painful symptoms, including the large, inflamed bubo. integrity of the most well cognise pandemics known to mankind is the plague, also known as the Black Death, whi ch plundered areas from Asia to Western Europe and carried on to the Americas. though the infection is not the most prevalent compared to many of the worlds other bacterial agents, the plague is one of the most feared. Normally, Yersinia pestis is a zoological disease, affecting smaller mammals and their fleas. However, the most influential 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 person 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 change magnitude the fatality of the Yersinia pestis bacteria.
