Our skin is filled with bacteria from head to toe. Arecent study suggests that the bacteria living on our skin may actually influence how quickly a wound may heal. These new discoveries may help treat patients with chronic wounds (cuts or lesions that just never seem to heal), which affect about 1 in 20 elderly people. Researchers from the University of Manchester Healing Foundation Center says “It’s our hope that these insights could help lead to better treatments to promote wound healing that are based on sound biology”. Chronic wounds are a serious problem because they may even lead to diabetes, poor blood circulation or even result in a person being confined to a bed or wheelchair.
The findings of bacteria in the gut have made it clear that not all bacteria cause harm and diseases, some bacteria are very beneficial to our health. In their recent study, the researchers compared the skin bacteria from people who heal and don't heal with chronic wounds. The results showed many different bacterial families, which suggests that there must be a bacteria that causes wounds to refuse to heal. The researchers also conducted a series of studies on mice to figure out why some wounds heal while others do not. They found that mice who lacked a single gene had a completely different array of skin microbiota. This made some bacteria harmful and slowed the mice's healing process. Researchers conclude that "Presumably, the mice's defect in the ability to identify bacteria means that they aren't able to mount the right type of response".
After these studies, the researchers concluded that there has to be link between skin microbiome and how we heal. This may help discover more treatments for people with chronic wounds.
