The source of all evil odor.

Sweat odor is caused by various bacteria, especially Aerobic Corynebacterium, in the armpits. These bacteria act on the secretions of the apocrine glands to produce ammonia and short-chain fatty acids that cause odor.

Five odors, including isovaleric acid, which causes sweat odor, and butanedione (2.3-Butanedione), which causes foot odor

When anaerobic bacteria such as ‘Microcosus,’ which hate oxygen, eat away at the calluses, the chemicals produced also cause a foul odor.

Since the secretion of apocrine glands (a type of sweat gland) becomes active after puberty, the number of patients with bromhidrosis is also the highest during this period.
