Abstract EN
The antimicrobial activity of plant extract of Peganum harmala, a medicinal plant has been studied already.
However, knowledge about bacterial diversity associated with different parts of host plant antagonistic to different human pathogenic bacteria is limited.
In this study, bacteria were isolated from root, leaf and fruit of plant.
Among 188 bacterial isolates isolated from different parts of the plant only 24 were found to be active against different pathogenic bacteria i.e.
Escherichia coli, Methicillin-resistant Staphylococcus aureus (MRSA), Enterococcus faecium, Enterococcus faecalis and Pseudomonas aeruginosa.
These active bacterial isolates were identified on the basis of 16S rRNA gene analysis.
Total population of bacteria isolated from plant was high in root, following leaf and fruit.
Antagonistic bacteria were also more abundant in root as compared to leaf and fruit.
Two isolates (EA5 and EA18) exhibited antagonistic activity against most of the targeted pathogenic bacteria mentioned above.
Some isolates showed strong inhibition for one targeted pathogenic bacterium while weak or no inhibition for others.
Most of the antagonistic isolates were active against MRSA, following E.
faecium, P.
aeruginosa, E.
coli and E.
faecalis.
Taken together, our results show that medicinal plants are good source of antagonistic bacteria having inhibitory effect against clinical bacterial pathogens.
