Bacteria could help fight acne
A friendly type of bacteria that oxidizes ammonia in human sweat may be able to help heal skin acne and ulcers, according to research presented at the 5th American Society for Microbiology Conference on Beneficial Microbes in Washington. ny AOBiome.
For the study, the biotech firm AOBiome split a group of 24 volunteers randomly into two groups, and gave one group a solution with Nitrosomonas eutropha–an AOB found in organic soil–and the second group a placebo solution. Before starting the study, the researchers took skin swabs of the volunteers, then instructed them to apply the solutions to their faces and hair for one week. The study lasted three weeks, with volunteers not using any hair products for the first and second week and resuming their regular routine by the third week.
Researchers found that the volunteers who used an ammonia-oxidizing bacteria (AOB) solution showed improvements to their skin with the presence of AOB. In fact, they determined that those improvements in their skin condition correlated with the level of OAB found in swab samples. The placebo group reported no such improvement. Further tests showed that the AOB changed the mix of bacteria in the skin.
The company says it will hold clinical trials to more rigorously test how well AOB works in treating acne and diabetic ulcers in human patients.
