Nematodes infected by MRSA are rescued by natural extracts. (A) Kinetics of the killing of C. elegans by MRSA ATCC33591, S. aureus NCTC-8325-4 and E. coli OP50 in liquid medium. Graph shows the mean ± SD of six replicates (20 worms / replicate) from a representative of three independent experiments. (B) Survival rate of MRSA-infected nematodes upon exposure to selected extracts (200 μg/mL)/compound (200 μM). Graph shows the percentage of survival at 72 hours post-infection when the assay was carried out without any treatment or treatment with different extracts/compound. Results are expressed as mean ± SD from a representative of two individual assays. (**) denotes significant difference in percentage of survival between untreated (no extract) and treated animals (p < 0.005).
