Question

bubonic bacteria research activity
apter 14 section 4
class time: 35 minutes
task: researching the organisms that caused the plague
instructions: the bubonic plague spread like wildfire through asia and europe during the 1300’s. many theories circulated regarding the plague’s origins, transmissions and cure, however it is now known that the plague was spread through a multistage process. this process began with yersinia pestis bacteria sitting in the bellies of fleas, which lived on rodents. these rodents then infested human populations and spread as the fleas bit human beings, thus transmitting the bacteria.
more serious forms of bubonic plague include pneumonic plague and septicemic plague. all of these forms co - existed during the middle ages. make use of the world wide web to explore each of the various forms of this disease, it’ pathology, transmission, symptoms and treatment. for full credit on this assignment you must have a minimum of three sentences for each description and a minimum of two sentences for each of the other headings. don’t get sick!!

Explanation:

The Bubonic Plague was a devastating disease in the 1300s. Caused by Yersinia Pestis bacteria in fleas on rodents, it spread to humans. More serious forms like pneumonic and septicemic plague also existed. For description, it was a widespread and deadly epidemic. Pathology and transmission involve the bacteria - flea - rodent - human chain. Symptoms include swollen lymph nodes, fever, and chills. Prognosis was poor historically, but modern antibiotics can treat it.

Answer:

Description: The Bubonic Plague was a highly contagious and deadly disease that swept through Asia and Europe in the 1300s, causing massive mortality and social upheaval. It was one of the most significant pandemics in human history. It led to changes in economic, social, and cultural aspects of the affected regions.
Pathology and Transmission: The disease was caused by the Yersinia Pestis bacteria. Fleas that lived on infected rodents carried the bacteria. When these fleas bit humans, they transmitted the bacteria, thus spreading the plague. Poor sanitation and close - living conditions facilitated its rapid spread.
Symptoms: Victims typically experienced painful and swollen lymph nodes, known as buboes, which gave the disease its name. High fever, chills, weakness, and fatigue were also common. In severe cases, internal bleeding and organ failure could occur.
Prognosis and Treatment: Historically, the prognosis for those infected was very poor, with high mortality rates. However, modern medicine has effective treatments. Antibiotics such as streptomycin and gentamicin can be used to treat the infection if diagnosed early. Isolation of patients and control of rodent and flea populations are also important preventive measures.
