Step-by-step explanation:
Conditions Resulting in the Formation of a Bubo
A bubo is a swollen, inflamed lymph node that develops as a result of a microbial infection. Among the options provided, bubonic plague is the condition that results in the formation of a bubo. The bacterial pathogen responsible for plague is Yersinia pestis. This noteworthy disease is characterized by the presence of swollen lymph nodes, and it is one of the three forms of plague in humans, the other two being septicemic and pneumonic plague. The bubonic plague has been historically significant, leading to countless deaths during pandemic events, with the most notorious being the Black Death in the 14th century.
The disease is transmitted to humans through the bite of an infected flea, which has typically fed on infected rodents. When an individual is infected with the bubonic plague, the lymph nodes closest to where the bacteria entered the skin become tender and swollen, forming a bubo.
