Scabies is a very painful disease, it is caused by many other diseases, some skin diseases and some internal diseases.
Scabies is often caused by dry skin, it is common in older people as the skin becomes drier with age, if the scabies are mild, it is possible and easy to treat, if it becomes severe, it is something to live with. But now scientists have discovered the reasons behind this itch for the first time.
Scientists have discovered that only bacteria can be the direct cause of itching, as previous research has shown that microbes, or ‘microbes’ that normally exist naturally on the skin, can cause diseases such as eczema. cause
A study published in the journal Cell found that a common bacterium called ‘Staphylococcus aureus’ causes itch by constantly sending itch signals to the brain.
This is the first time scientists have found that bacteria alone can be the direct cause of scabies, with previous research showing that microbes or ‘microbes’ that normally occur naturally on the skin. , cause diseases like eczema.
However, new research has now revealed that the bacteria release an enzyme that activates a protein in the skin that sends itchy signals from the skin to the brain. The presence of the bacteria Staphylococcus aureus and the resulting release of enzymes can disrupt the natural balance of microbes on the skin.
To restore this balance, the sensation of itching continues until the skin microbial balance is restored, and patients continue to scratch their skin for relief, resulting in skin irritation and damage. can reach
“We’ve found a new reason why people feel itchy, the bacterium called staph aureus, which causes atopic dermatitis,” said Dr. Isaac Chiu, an associate professor of immunology at Harvard Medical School and co-author of the study. are present in patients with This finding suggests that skin bacteria and inflammation from medical conditions are linked.
“When we started the study, it wasn’t clear whether the itch was a result of inflammation,” said author Dr. Levin Deng.
He said that our research has shown that itching and inflammation are two separate conditions, inflammation is not always required to cause itching but inflammation can worsen due to itching.
