The effect of some plant extracts on the resistance Staphylococcus spp

Abstract

Staphylococci spp ubiquitous, including a different species as normal flora. The most virulent and resistant to antibiotic are Staphylococcus aureus and mutans, species which colonizes epithelial surfaces and causes dangerous humans infections. The objectives of this study is studying and Using the agar agar weal diffusion process, researchers tested the The degree of susceptibility of bacteria from one type of plant extract to another varies for six different concentrations using several methods (50, 100, 200, 300, 400, 500 mg/ml) of each Aqueous and alcoholic plant extracted were used then evaluated. The alcoholic Ziziphus In this study, we see that the strongest activity of the extract against the tested bacterium Ziziphus. this analysis. Turmeric, alcoholic, and aqueous extracts, on the other hand, had comparable antimicrobial activity but at higher concentrations. However, against S. aureus and S. mutans, the aqueous extract of cuminum cyminum had no inhibitory action. The S. aureus isolates seemed to be resistant to the extracts of Ziziphus and Tumeric. The S. mutans isolate, on the other hand, was more susceptible to cuminum cyminum, but only at low concentrations
