Human skin is home to amultitude of microbes , including some that are helpful and some that could potentially be harmful . Now , a pocket-size pilot subject area show that it might be potential to harnessthe good bacteria , put them into a lotion and then spread that app onto the skin to fight off the bad bacteria .
In the bailiwick , researchers adopt bacterial samples from patients ' skin , foot out sealed species and culture them in a research lab , and then put these bacteria into a lotion . They found that , for five patients with a skin experimental condition , the bacteria - rich app protected them against infections by destroying harmfulgerms on their hide .
The findings show that " bacteria have a very important role to play in our immune defense , " Dr. Richard Gallo , chair of the Department of Dermatology at the University of California , San Diego , and one of the field authors , tell Live Science . The study waspublishedFeb . 22 in the diary Science Translational Medicine . [ soundbox hemipteran : 5 Surprising fact About Your Microbiome ]
In the sketch , the researchers looked atpatients with eczema , a stipulation which make fretful , reddish , inflamed skin . In some mass , the precondition is chronic , which mean that it recurs again and again .
Eczema also make affected role more susceptible tostaph infection . ( " Staph " is unretentive for the bacterial group known asStaphylococcus . )
The research worker determine that the patient role who hadpersistent eczematended to be substandard in the friendly bacterium that kill a type of bacteria calledStaphylococcusaureus . In contrast , mass without eczema have an abundance ofthe helpful bacterium , according to the study .
The investigator analyzed the well-disposed breed of bacteria , which are also forms of staphylococcus , but eccentric that do not cause harm . They line up that these bacterium produce two lifelike antibiotic agents , make love as " antimicrobial peptides , " according to the study . The human physical structure also makes these substances , but the young study suggests that the bacteria on the skin do a better problem of producing them , the researchers said .
In experiment using cop skin and mouse , the researchers found thatthe " beneficial " bacteriastrongly inhibited the growth of several harmful staphylococcus air , includingmethicillin - resistantStaphylococcus aureus , or MRSA , a pathogen that is resistant to multiple type of antibiotics .
What ’s more , the animal experimentation showed that even as pathogens were kill off , other colonies of bacteria keep on to boom . Conversely , traditionalantibiotics tend to destroyboth helpful and harmful germs all at once , potentially weaken people ’s immune reaction .
The five patients in the subject field had only bantam amount of money of thegood bacterium on their skin , and all tested positive for the eccentric of staphylococcus that causes infection . The researchers swabbed the patient ' skin , and cultured the few friendly straining of bacteria they could come up . Then , they grew more of these bacteria in the lab , and added the microbes to a program .
To examine whether the dependable bacteria would bolt down harmful bacterium , and avail keep infection , the researchers had the patient apply their own personalized microbe - containing lotion to one arm and even moisturizer to the other . After 24 hour , in all five affected role , only the arms treated with the microbe - containing lotion show up near full improvement , and in two patients , the staphylococcus pathogens were destroyed exclusively .

While the result of this psychometric test were assure , question stay .
First , the study was very little , so the results need to be affirm in big studies . In addition , although the lotion prevented skin infections , it ’s not light whether it would improve the patients ' skin condition , Gallo said .
Researchers also do n’t bed if the affected role were " bring around " of the staphylococcus pathogen , or if they would need to keep reapplying the lotion in the future .
For this study , the bacterium in the software came from the patient role ' own skin , but that ’s already changing .
" The next - point trial that is afoot now is to just utilise one universal nisus and apply it to everyone , " Gallo say .
