INTRODUCTION
Black death was the most epidemic disease is the history of human. It was resulted in the
death of 75 to 200 million people. This was occurred in 1346-1353 in Eurasia. There were
various theories developed in identifying the cause of black death but after the final analysis it
was found out that the pathogens which are responsible for black death was Yersinia pestis
bacterium (Greg, 2016). This report contains the bacterial symptoms of black death and the ways
by which this disease got transmitted. This assignment also shows the treatment methods used to
cure the victims.
BLACK DEATH/BUBONIC PLAGUE
This disease was caused by bacterium Yersinia pestis, a bubonic plague which circulates
in the wild rodents. They live in high density and high in numbers. Such kind of places is also
called as plague focus or plague reservoir. Such kind of plague in human arises when the black
rats or rodents became infected. This is exposed after one to seven days. This is majorly spread
by some infected fleas which are from small animals (Bubonic Plague, 2017). This can also be
exposed from getting in contact with the fluid flowing from the deal plague or infected animals.
The bacteria will enter in the body by the bite of any infected flea bite. These bacteria will travel
through lymphatic vessels which will cause it to swell. The diagnosis has been made by finding
the bacteria running in blood, lymph nodes or sputum.
SYMPTOMS
The bubonic plague is very rarely spread through the contact of person to person. The
lymph nodes is getting affected by this plague the most. These nodes are another part of lymph
system. The bacteria will start showing its effects within 3 to 7 days (Charlotte, 2014). The
person will develop some symptoms of flu like headache, fever, weakness, chill tender lymph
glands and swollen. The dying tissue starts appearing black which will cause the bleeding of
tissues and in severe cases it may cause death.
INFLUENCE
The diagnosis of this particular plague is dependent on the identification of organisms in
the sample of blood tissues. There are various anti-biotic available for treating this. Some of
them are ciprofloxacin, streptomycin, gentamicin etc. Those people who are suffering from this
