uncivilised gorillas in Gabon eat several of the same plants traditional healers in the part exercise , and these plants show antibacterial properties in lab dishes , scientists found .
In a novel study , compounds in the bark of unlike trees showed potence against antibiotic - tolerant strains ofEscherichia coli , which can cause hard - to - treat infections in humans , including pneumonia and bloodstream infections . The researchers behind the work recall these plants from Gorilla gorilla ' diets could lead to predict drug for people , but much more work is needed to develop such medication .
A fromager tree (Ceiba pentandra).
In the report , bring out Wednesday ( Sept. 11 ) in the journalPLOS One , researchers observed westerly lowland gorillas ( Gorilla Gorilla gorilla Gorilla gorilla ) in Gabon ’s Moukalaba - Doudou National Park , recording what plants they ate . They also interviewed people in the nearby village of Doussala , including healers and herbalists , about flora used in their traditional medical specialty .
Past research by the grouphad revealed drug - resistantE. coliamong Gorilla gorilla in the park ; these microbes can potentially get disease in humans , but apes can often carry the bug without symptom . The researcher wanted to interpret how the Gorilla gorilla host pathogenicE. coliwithout suffering serious disease , and they hypothesized that it might have to do with plant gorillas rust that are n’t of the essence to their nutrition — such as Sir Herbert Beerbohm Tree barque .
touch : serious ' poinsettia strain ' are a growing scourge , and antibiotics ca n’t stop their rise . What can ?
A fromager tree (Ceiba pentandra).
The team identified four native plant species were both eat by gorillas and used in traditional medication : the fromager tree ( Ceiba pentandra ) , giant scandalmongering mulberry tree ( Myrianthus arboreus ) , African Tectona grandis ( Milicia excelsa ) , and fig Sir Herbert Beerbohm Tree ( Ficus ) .
" One of the comprehension criteria for the various plant studied in our research was the fact that the selected plant consume by gorilla was also already used in traditional medical specialty , " take authorLeresche Even Doneilly Oyaba Yinda , a bacteriologist at the Interdisciplinary Medical Research Center of Franceville , recite Live Science in an e-mail .
The traditional therapist use the plant life in infusion , descent and salve intended to treat a range of shape , including coughing , stomach ulcers , looseness and fatigue . For gorillas , tree diagram bark is n’t a staple of their diet — they mostly eat fruit — but primatologists consider skin a fallback food for the ape when their preferred foods are less available .
The researchers create barque gunpowder extracts from each tree and then test the bark extract ' effects on bacterium by set them in petri sweetheart with drug - resistantE. coli . These song had previously been sampled from the gorillas , and the researchers observed whether and how well the excerpt inhibited bacterial emergence .
The bark of all four tree had antibacterial power , with each showing some activity against at least one of the 10E. colistrains tested . The fromager tree diagram ’s bark demonstrate the good results at inhibitingE. coligrowth and worked against all 10 strains . However , the researchers did n’t identify which chemical substance within the extract were creditworthy for the effect .
All of the works also check various phenols , alkaloids , flavonoids and proanthocyanidins , which are compounds with anti - inflammatory , anaesthetic and antiviral holding .
These four plants could be promising to treat multidrug - immune bacterial infections in humans , Yinda said . Their antibacterial and antioxidant property may also excuse their use in traditional music , he tot .
The scientist have n’t directly meditate how eating these flora might involve gorillas ' health , or whether dissimilar doses of the plants might have dissimilar effects . That said , other great apes have been jazz to use plants with medicinal properties : chimpanzees periodically use up leavesthat can bring in leech from their gut , and orangutansapply leaves to their injury . Traditional medicine in the region where these primates liveoften utilise the same plantsto treat the great unwashed with various conditions .
Assuming the Sir Herbert Beerbohm Tree bark is good to apes , it might be tempting to take cues from the primates — but it ’s not known how human trunk will respond to the same substances .
" There ’s a sight of hope there , but there ’s a lot of pitfalls too,“Jessica Lodwick , a primatologist free-base at Oregon State University who was not involved in the sketch , tell Live Science . Since we ’re closely related to to peachy apes genetically , it ’s possible , but not sure , that we ’d respond similarly to these plants , Lodwick said . For now , we do n’t yet experience what the plant life do privileged Gorilla gorilla ' bodies either .

" We have not been able-bodied to carry out toxicology and cytotoxicology [ toxicity to prison cell ] work to confirm the absence seizure of side burden , " Yinda say . " [ But ] the fact that these plants have been used since ancient clock time in traditional medicine , and that gorillas go through them , was one of the factor that led us to see them comparatively safe and in force for humans . "
depend to gorillas to interpret plants ' medicinal property could also reveal what plant we need to protect .
" Certain tree species might be take for logging , and if we do n’t sleep with which tree provide awe-inspiring medicative applications … then we ’re just proceed to destruct our pharmacy — nature ’s drugstore , " Lodwick said . " It ’s going to affect us , and it ’s going to touch on the creature that are using it . "
