transmission system of the Plague to HumansAbstractYersinia pestis is a bacterium that has been well know to mankind for centuries. Its mechanisms of survival in wide assortment of species are extraordinary. The former of this bacterium is dependent on its manipulation of the immune arranging of its innkeepers. Its means of survival in the flea and its use of the flea as a vector to other desirable hosts portray this bacteriums true capability. This flea is the of import cause of the bacterium to other animals, especially humans. However, the bacterium does not respectable stop here it uses its coded proteins to inhibit the hosts immune system and the hosts cellular functions to aid in its survival in the organism.One of the most deadly diseases to strike mankind is the pesterer. The plague has survived for centuries and has claimed the lives of millions passim the years. The plague is caused by a gram-negative bacterium known as Yersinia pestis.

At times, transmission can also occur from infected rodents, cats or other animals finished bites and scratches (Phillips, 2004). The bacterias key for survival lies in its vast variety of hosts.

However, the process that the bacteria must go through in order to infect a human relie... ...berlain/Website/lectures/lecture/plague.htm2.
