In this study, the ability of two antibiotics daptomycin and pantoyl lactone to inhibit growth of horse originated pathogen Streptococcus equi by disrupting plasma membrane of the bacterium was investigated using agar diffusion and micro tube dilution methods. The results obtained from this study indicated that daptomycin was more effective in inhibiting the growth of the pathogen in vitro than...

We have investigated the antibacterial, antifungal and cytotoxic activities of two flavonoids isolated from Retama raetam flowers using the disc diffusion and micro-dilution broth methods. The cytotoxic activity was tested against Hep-2 cells using the MTT assay. The compounds licoflavone C (1) and derrone (2) were active against Pseudomonas aeruginosa and Escherichia coli (7.81-15.62 μg/mL) an...
