In vitro, the Antimicrobial activity of some medicinal plant extracts on the growth of some bacterial and fungal pathogens

Abstract

This study was done during the period between October to December 2018. The antimicrobial activity of ethanolic extracts of some medicinal plants Daucus carota (seeds), Rheum ribes (roots), Rumex vesicarius (leaves) and Punica granatum (peels) were tested against some clinical isolate of Gram-negative bacteria (Proteus mirabilis, Helicobacter pylori and Klebsiella pneumonia), Gram-positive bacteria (Staphylococcus epidermidis and Streptococcus mutans) and against some pathogenic fungi Trichophyton violaceum and Microsporum audouinii that get from Al-Diwaniyah teaching hospital. The result showed P. granatum have the highest antibacterial activity against all bacterial isolates under study than other extracts, the diameters ranged between (24.4-31.3) mm followed with the D. carota extracts which the diameters ranged between (20.4-28.5) mm, also the result obtained that the most inhibition percentage against fungal isolates was with P. granatum extract which ranged between (64.5-68.6) %, followed with D. carota extract which ranged between (60.7-63.4) %.
