malignant edema; malignant oedema
Veterinary medical term for a rapidly spreading, often fatal soft tissue infection caused by Clostridium bacteria, primarily in livestock.
When cattle develop malignant edema, symptoms worsen rapidly.
Malignant edema is caused by bacteria of the genus Clostridium.
気腫疽 (blackleg) is also a clostridial infection in livestock, but typically affects muscle with gas production, while 悪性水腫 is characterized by severe edema without prominent gas formation.
Compound of 悪性 (malignant) and 水腫 (edema, dropsy). The term is a direct calque from Western medical terminology.
