Biological Effect of Some Plant Extracts on Germ Isolated Staphylococcus aureus from Different Skin Infections

This study included the isolation and identification of Staphylococcus aureus (S.aureus )from different cutaneous infections including secondary pyoderma(wound and burn ) infections , Impetigo contagiosa, Folliculitis and Boils (Furuncles) . These patient were under treatment in the emergency unit, and out patients of dermatology clinic<br />both within the Mosul Medical City.(24 ?)samples were collected, (155) of them were of (S. aureus ) by a ratio of ( 62.7%) . The highest rate S.aureus infection (76.1 %) was isolated in impetigo while the lowest<br />rate ( 37.5%). There was different percentage of bacterial infection according sex and age. The alcoholic and aquatic extracts were prepared. The inhibitory effect of the extracts of Lillium Candidum flowers ,<br />Hedra helix leaves , Carduus Benedictus and Portulaca Oleracea leaves was studied against all the isolated bacteria using disk diffusion method comparing with standard method and turbidity. In addition, the Minimum Inhibitory Concentration ( MIC ) and the Minimum Bactericidal Concentration (MBC) was determined for these extracts against the bacterial isolates under study.<br />The results showed that the Alcoholic extract of Portulaca Oleracea leaves had the best effect on bacteria.
