First, bubonic (rhymes with pneumonic but is altogether different) is a local infection sequestered in a lymph node.
The bubonic plague of the 1340s was often blamed on Jews by the Ahmadinejads of the era.
The patient has been described by some reports as having “bubonic” plague and by others as having developed the “pneumonic” form.
"characterized by swelling in the groin," by 1795, from Latin bubo (genitive bubonis) "swelling of lymph glands" (in the groin), from Greek boubon "the groin; swelling in the groin" + -ic. Bubonic plague attested by 1827.
