Purpose: Recently, the unconscious use of antibiotics and the gain of resistance of pathogenic microorganisms lead to new antibiotic searches. In this study, it was aimed at researching the antimicrobial activity of curl extract (Quercus hartwıssıana Steven) against bacterial and fungal pathogens. Tools and Methods: The extraction of the strawberries is carried out with ethanol, formaldehyde, acetone, ethyl acetate and methanol solvents. After absorbing 50μl of these extracts into the sterile discs, the discs are dried in a sterile environment for 24 hours in order not to affect the result of the solvents found in the extracts. The method of disque diffusion is Pseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, Salmonella spp. Methylococcus aureus (MRSA), methylococcus aureus (MSSA), Staphylococcus epidermidis, Enterococcus spp., Candida albicans, Candida glabrata and Candida tropicalis species have been studied antimicrobial activity: In the study, ethanole prepared the extractive extractive zone diameter Enterococcus spp.(8 mm) and S. epidermidis (8 mm); extracts prepared with formaldehyde and ethyl acetate, extracts prepared with E. coli (16 mm, 28 mm); extracts prepared with acetate, extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts prepared with the extracts. In the shell (21 mm); it is determined that the extract prepared for methanole forms the isegenius zone diameter in the MSSA shell (28 mm). In May, the extracts of the ethanol are prepared by the diameter of the zone C. In glabrata swallow (12 mm); the diameter of the extractive extractive zone prepared with formaldehyde was found in C. albicans (28 mm) and C. tropicalis (28 mm) swallow; the diameter of the extractive zone prepared with acetone, ethyl acetate and metanole was found in C. albicans swallow (19 mm, 30 mm, 22 mm). The result: The extract obtained by ethyl acetate is found to be a wider sensitivity zone diameter in the studies obtained in comparison to the extract obtained by other solvent. Since the speculative zone diameter is formed in the E.coli, S.aureus and C.albicans species, it is considered important to conduct in vivo antimicrobial studies on the inhibitory effect of naturally grown strawberries in our country.
