What bacteria causes armpit odor? Uncovering the microbial culprits that cause odors
Underarm odor is a common problem that plagues many people, and its root cause is closely related to the proliferation of specific bacteria. This article will combine hot topics and scientific data from the entire Internet in the past 10 days to provide an in-depth analysis of the types of bacteria that cause armpit odor, their mechanisms of action, and how to deal with them.
1. Main types of bacteria causing armpit odor
Research shows that armpit odor is mainly produced by the following three types of bacteria decomposing sweat:
| Bacteria type | Proportion | Metabolites | Characteristic odor |
|---|---|---|---|
| Staphylococcus aureus | about 60% | short chain fatty acids | sour smell |
| Corynebacterium | about 30% | Sulfide/ammonia | Onion/sweat odor |
| Micrococcus | about 10% | isovaleric acid | Cheese sourness |
2. The scientific mechanism of bacteria causing odor
These bacteria produce odor through the following steps:
1.Sweat breaks down: Proteins and lipids secreted by apocrine glands are broken down by bacterial enzymes
2.Metabolic transformation: Bacteria convert odorless precursors into volatile organic compounds
3.Odor release: Small molecular substances such as sulfides and short-chain fatty acids volatilize through pores
3. Key factors affecting bacterial reproduction
| Influencing factors | Mechanism of action | Data support |
|---|---|---|
| Humidity | Create a breeding ground for bacteria | When humidity is >70%, bacterial colonies grow by 300% |
| pH value | alter microbial communities | pH6.5-7.5 is the most suitable for pathogenic bacteria |
| genetic factors | Determines the secretion of apocrine glands | Asians have a 30% lower incidence rate |
4. Latest research hot spots and solutions
1.microbiome therapy: Adjust the balance of armpit flora through probiotics
2.Targeted antibacterial technology: Development of antimicrobial peptides that specifically inhibit Corynebacterium
3.Sweat gland regulation:Clinical study on botulinum toxin injection reducing apocrine secretion
5. Daily prevention and control suggestions
• Choose aTriclosanortea tree essential oilantibacterial products
• dressbreathable cottonClothing to keep underarms dry
• Diet controlspicy foodandred meatingest
• Use regularlyWeakly acidicCleansing Products Adjust Skin pH
The latest research shows that by precisely regulating the microbial community under the armpits, odor can be reduced by more than 80%. In the future, with the development of microbiomics, personalized treatment plans for armpit odor will become possible.
