Abstract
The study is included preparation of aqueous and ethanolic hot extracts for Potamogeton perfoliatus L. and Ceratophyllum demersum L. plants and tested their biological activity against nine isolates bacteria: four isolates a Gram positive Staphylococcus aureus (MRSA), Streptococcus pyogenes, Streptococcus spp. Staphylococcus aureus and five isolates Gram negative Klebsiella pneumonia, Pseudomonas aeroginosa, E. coli, Serretia spp. Proteus mirabilis by using three concentration (250 mg /ml ,125 mg /ml ,62 mg /ml ) for all aqueous and ethanolic extracts as well as the study chemical tests for all plants extracts to identify active compounds. An aqueous and ethanolic extracts plants showed defferent inhibition diameters zone .the highest inhibition diameter zone was (20 mm)in concentrations (250 mg /ml and 125 mg / ml) for alcoholic extract for Ceratophyllum demersum plant while the aqueous extract for Potamogeton perfoliatus plant showed highest inhibition diameter zone (20 mm )in concentration (250 mg /ml)comparative with alcoholic extract. The result showed that all isolates resistant to the following antibiotic (KF,OX,CL,B,CX,ME) except two isolates Klebsiella pneumonia Staphylococcus aureus (MRSA) were sensitive to antibiotic (CL) .
