Bubo (inflammed lymph node): remembering the plague

• The term comes from Greek:βoυβớν = boubon = swelling of the inguinal gland

• In other words it is an adenopathy of inguinal lymph mode – also called bubon.

• Today the term is less and less used probably because Hippocrates (of Kos) described it for thé plague, which was prevalent in Ancient Times.
• The bubo is the most prevalent manifestation in the plague: it appears 2-5 days after the bacteria (Yersinia Pestis) is inoculated by bites from fleas living on rodents (rats).
• Alexander Yersin (student of Louis Pasteur) discovered the responsible agent in 1894 in Indochina by examining tissue from the bubo. At the same time a Japanese Baron and physician Kitasato Shibasaburō (北里 柴三郎) was unable to find the agent when examining internal organs and blood.

• The term bubo is/was also used in sexually transmitted conditions such as syphilis, chancroid, lymphogranuloma venereum (Nicolas-Favre disease) and tuberculosis (scrofuloderma)
