bubo-, bubon- +
(Greek > Latin: groin, swollen gland)
Antibubonic vaccine, a sterilized bouillon culture of the plague bacillus; antibubonic measures.
A feature of a number of infectious diseases including gonorrhea, syphilis, tuberculosis, and the plague; hence, the bubonic plague. The odd word bubo comes from the Greek boubon; meaning, "groin" or "swollen groin".
Bubonic plague usually starts one to five days after infection with a fever, shivering, and a severe headache.
Sometimes, septicemia (blood poisoning) is an early complication and it may cause death before other signs of the disease appear.
The plague may have three clinical forms: bubonic, pneumonic (pneumonia), or septicemic (blood poisoning). The misleading use of the word bubonic (which means that it is characterized by buboes, or inflammatory swellings of lymph nodes) has developed into the mistaken idea that the real plague is necessarily bubonic and that non-bubonic types are a different disease altogether.
The mild forms of plague infections are bubonic while the other forms are severe and almost always fatal, unless properly treated; and the bubonic plague consists of about three-fourths of the total kinds of plague cases.
2. An inguinal hernia; especially, one in which the protrusion of the intestine is limited to the region of the groin.
3. A femoral or inguinal hernia; especially, an incomplete variety in which the hernial pouch descends only as far as the groin, forming a swelling there like a bubo.
Chancroid is a sexually transmitted disease caused by the bacteria haemophilus ducreyi. It causes multiple painful ulcers on the penis and the vulva often associated with tender and enlarged inguinal (groin) lymph nodes.
