US scientists said they took samples of thousands of microbes and bacteria found in the saliva of a "brown bear" living in eastern Siberia's nature, and used a technology that rapidly assesses the types of microbes that can be developed to eradicate the most dangerous bacteria that highly resist the available antibiotics.
The bacteria and the microbiota of animals are active in fighting exotic microbes, so they have features that qualify them to be used as compounds of antibiotics.
Scientists from the Rutgers University, who published their findings in the Proceedings of the National Academy of Sciences journal, said that they placed a bacterium from a wild animal's mouth in an oil droplet to see if it inhibits harmful bacteria, such as Staphylococcus aureus. New types of staphylococcus aureus that resist antibiotics have recently emerged, most notably methicillin-resistant staphylococcus aureus.
Konstantin Severinov, one of the study authors, said that "it is tedious to look for bacteria that produce antibiotics by testing them on Petri dishes. We managed to swiftly detect useful types of bacteria found in the bears' saliva."
After studying hundreds of thousands of oil droplets containing bears' microbes, scientists found that one of the studied bacteria killed the Staphylococcus aureus.
