Effect Of Extracts of Some Edible Fungi on The Growth of Staphylococcus Aureus Bacteria Isolated From Wound Exudateinstr.

Abstract

   The current study included testing the natural bioactivity of aqueous and alcoholic extracts of Morchella elata and Sparassis spathulata to evaluate their ability to inhibit the growth of Staphylococcus aureus bacteria, isolated from wounds in a hospital in Baghdad. The study used the drilling diffusion method. The results showed that the aqueous extracts were more effective in inhibiting bacterial growth than the alcoholic extracts. The highest inhibition rate was recorded at aconcentration of 40 mg/ml, reaching 14.3 and 12.7 mm for Morchella elata and Sparassis spathulata, respectively. This compares to the average inhibition diameters of the alcoholic extracts which reached their maximum at a concentration of 40 mg/ml reaching 10.9 and 9.4 mm for the two fungal extracts respectively. When examining the sensitivity of bacteria to antibiotics the most effective were gentamycin and clindamycin, which reached a growth diameter of 12.9 and 10.5 mm respectively. They were less effective for the rate of inhibition of bacterial diameters using aqueous extracts of Morchella elata and Sparassis spathulata at a concentration of 40 mg/ml.
