Objective:To evaluate the possible in vitro interaction between ethanolic extracts of Rhus coriaria[***)(seed),Sacropoterium spinosum(***)(seed),Rosa damascena(R. damascene)(flower) and certain known antimicrobial drugs including oxytetracycline HCl, penicillin C,cephalexin,sulfadimethoxine as sodium,and enr of *** synergy study was carried out against 3 clinical strains of multidrug-resistant Pseudomonas aeruginosa (***).Methods:Evaluation of synergy interaction between plant extracts and antimicrobial agents was carried out using microdilution ***:The results of this study showed that there is a decrease in the MIC in case of combination of ethanolic plant extracts and test antimicrobial *** most interesting result was that the combination between R. coriaria and these antibiotics,showed a high decrease in minimum inhibitory concentration(MIC), and a strong bactericidal activity against these ***:These results may indicate that combinations between *** extract and these antibiotics could be useful in fighting emerging drug-resistance ***,which may due to that *** extract contain natural inhibitors working by different mechanisms or inhibiting efflux *** we have experiments underway leading to the identification of the active molecules present in ***,in vivo experiments are needed to confirm pseudomonal protection.

Objective:This study was conducted to update the prevalence of methicillin-resistant Staphylococcus aureus(MRSA) isolates among human clinical *** isolates recovered from Northern Palestine,to evaluate the possible presence of vancomycin-Resistant ***(VRSA) and vancomycin- intermediate resistant *** strains(VISA) and to determine the antimicrobial susceptibilities of these clinical ***:The in vitro activities of 11 antibiotics against 204 non-duplicate *** isolates from clinical samples in North of Palestine were determined by the diskdiffusion *** samples were isolated between June 2006 and December *** minimum inhibitory concentration (MIC) of vancomycin for 115 methicillin resistant Staphylococcus aureus(MRSA) strains was carried out using the agar dilution ***:One hundred and fifteen(56.4%) of these isolates were MRSA and according to their antibiotic profile these are multidrug resistant(resistant to three or more non-p-lactam antibiotics). Ninety nine(43.6%) isolates were methicillin sensitive ***(MSSA),forty four of MSSA isolates(44.4%) were multidrug resistant,while forty five(45.6%) were non multidrug *** results showed that the most common resistance(95.6%) was to *** strains of MRSA have shown to be vancomycin- intermediate resistant,had MIC of 4μg/rnL and 8μg/mL and these vancomycin- intermediate resistant *** strains(VISA) are resistant to all antibiotics ***:According to our information this is the first study report about VISA in Palestine.
