Antibiotic resistance differentiates Echinacea purpurea endophytic bacterial communities with respect to plant organs.


PMID 25283726

Abstract

Recent findings have shown that antibiotic resistance is widespread in multiple environments and multicellular organisms, as plants, harboring rich and complex bacterial communities, could be hot spot for emergence of antibiotic resistances as a response to bioactive molecules production by members of the same community. Here, we investigated a panel of 137 bacterial isolates present in different organs of the medicinal plant Echinacea purpurea, aiming to evaluate if different plant organs harbor strains with different antibiotic resistance profiles, implying then the presence of different biological interactions in the communities inhabiting different plant organs. Data obtained showed a large antibiotic resistance variability among strains, which was strongly related to the different plant organs (26% of total variance, Pxa0
